PREFACE

Dear Colleagues of Universal Corrosion Community,

We are honored to host the KORSEM’18-The XVth International Corrosion Symposium in Turkey.

On behalf of the Organization Committee, it is my privilege to extend our regards to all our invited

lecturers and the participants which shared their special scientific findings and high academic knowledge,

in the ever expanding world of corrosion.

I would like to commence by quoting some specific numbers to give a broad picture of the status of

the KORSEM’18. The number of abstracts submitted was about 115; approximately 90 oral presentations

have been scheduled, together with 25 posters.

We had the opportunity to listen to about three Invited and Pleanary Talks in this meeting, including

our world-renowned Plenary and Invited Speakers: Prof. Dr. Ali Fuat Cakır (Istanbul Technical

University), Prof. Dr. Kemal Nisancioglu (Department of Materials Technology, Norwegian University of

Science and Technology/Norway), Prof. Dr. Nazan Savas (Hatay Mustafa Kemal University)

KORSEM’18 has received the support of many people and companies. Their support to the

symposium as a whole is duly appreciated. Particularly, we would like to thank Borçelik Çelik Sanayii

Ticaret A.Ş, TUBITAK (The Scientific and Technological Research Council of Turkey), Hatay

Metropolitan Municipality and Hatay Mustafa Kemal University Rectorate for their great support.

The organizing committee, the scientific committee and the board members of the Corrosion

Association participated in the scientific meetings and presented oral and poster presentations. On the

other hand, we are happy to turn KORSEM’18 into a worldwide event. I would also like to express my

gratitude and gratitude to all my colleagues who have contributed to this organization.

I wish KORSEM’18 will give you an efficient experience. I hope that KORSEM’18 will offer a

versatile platform for formal and informal discussions to both academic colleagues and industry

stakeholders and will encourage new collaborative views.

On the Behalf of Organizing Committee

Prof. Dr. Ali Tuncay OZYILMAZ

President of Symposium

TOWARDS UNDERSTANDING ATMOSPHERIC AND AQUEOUS LOCALISED

CORROSION OF AA6063-T5 ALUMINIUM ALLOY – A COMPREHENSIVE

STUDY USING TIME-LAPSE SKPFM, IN-SITU AFM AND CONVENTIONAL

ELECTROCHEMISTRY

Aluminum alloy AA6063 has been widely used as structural and functional materials and found

versatile usage in various industries. Exposure to indoor and outdoor can lead to various corrosion

scenarios, requiring the need for a thorough understanding of the corrosion behaviour in aqueous as well

as atmospheric conditions. The corrosion resistance under immersed, aqueous conditions have been well

studied, but exposures to humid-air, atmospheric conditions remained by far less studied and understood.

Localised corrosion under aqueous conditions can lead to totally different corrosion degradation scenarios

as contrasted to atmospheric exposures and may even not be compared with each other, necessitating the

examination of the material with scrutiny.

Localised corrosion of aluminium alloys is highly complex and has remained less understood due to

multi-scale structural and chemical heterogeneities in the microstructure. The latter is due to galvanic

inter-coupling among microstructural constituents, often leading to intergranular or pitting corrosion. It

has vital importance to know which sites in the microstructure have most susceptibility to localised

corrosion in order to assess the structural integrity of the alloy. There is further need to know the

corrosion process to understand if there is a corrosion (reiterative) sequence existing among

microstructural constituents which may be impeded or slowed down by countermeasures.

In this work, the susceptibility to localised corrosion of a commercial aluminium alloy AA6063-T5

has been studied under both immersed aqueous and atmospheric thin-film electrolyte exposure conditions.

The aqueous corrosion behaviour was studied by conventional electrochemistry and in-situ atomic force

microscopy (AFM) using exposure to chloride-containing solutions. Atmospheric corrosion

measurements were carried out by the contamination of chloride producing corrosive electrolytes at

elevated humidities at room temperature.

The scanning Kelvin probe force microscopy (SKPFM) was used to characterise the microstructure

for local susceptible sites to corrosion in both dry and humid environments with and without the presence

of chloride. In-situ AFM was used to monitor the onset and propagation of localised corrosion.

Comprehensive microstructure characterisation using scanning electron microscopy (SEM) and X-ray

diffraction (XRD) enabled, hence, understanding of susceptible sites to corrosion. SKPFM revealed large

and multi-scale Volta potential heterogeneities associated with sensitised regions next to intermetallic

phases, indicating enhanced electrochemical susceptibility. SKPFM further demonstrated nobility

inversion of microstructural components during exposure to corrosion, changing the localised corrosion

scenario. Dissolution was found to initiate around interphase boundaries adjacent to cathodic

intermetallics on anodic phases, being influenced by the local electrochemical conditions, being in good

correlation with SKPFM data. Post-corrosion SEM/EDX analysis revealed de-alloying of corrosion-

active sites. The results are discussed in light of better understanding localised corrosion behaviour of

6xxx-series aluminium alloys.

The quality of passive films on metals determine their corrosion resistance, and therefore it has

paramount importance to understand the reasons for local breakdown in corrosive environments. The

passive film on duplex stainless steels is complex due to locally varying chemical and structural

heterogeneities. The nature of the passive film on austenitic and ferritic grains remained less understood,

and little is known about its interaction with corrosive electrolytes. Monitoring the passive film behaviour

during corrosion reactions in real time would be beneficial in order to understand structural and chemical

changes of the surface to associate with degradation mechanisms.

This work presents new findings about the passive film formed on super duplex stainless steel in

ambient air and corrosive environments, studied by synchrotron grazing-incidence X-ray diffraction

(GIXRD), X-ray reflectivity (XRR), and X-ray fluorescence (XRF). The passive film, formed in air, was

seen to be a nano-crystalline mixed-oxide. Electrochemical polarisation to the passive region in aqueous 1

M NaCl at room temperature resulted in an increase of the passive film thickness, de-alloying of Fe, and

partial loss of crystallinity. The thickness of the passive film reaches maximum prior to the onset of the

transition to the transpassive state of the steel, whereas a reduction of its density occurred due to the

generation of defects mainly caused by de-alloying phenomena. The passive film thickness as well as

density were seen to decrease during transpassive corrosion, with the extent increasing with the time and

magnitude of anodic polarisation. After termination of polarization to the transpassive regime,

reformation of the mixed-oxides was observed, showing a thicker, semi-crystalline, and more defective

nature with further new oxides/hydroxides. The onset of corrosion was seen to begin with dissolution of

Fe with its compounds, followed by Cr, Mo, and Ni. The alloy surface layer beneath the passive film was

seen to increase in thickness and density, suggesting enrichment of Ni and Mo during transpassive

corrosion. The passive film evolution in corrosive environment is discussed in light of better

understanding localised corrosion of super duplex stainless steel.

ZAMAK-2 ALLOY PREPARED by POWDER METALLURGY and

INVESTIGATION of CORROSION BEHAVIOR in 3.5% NACI

Mehmet Burak Koca*1, Rasiha Nefise Mutlu1, Gülfeza Kardaş1, Birgül Yazıcı1 1Çukurova Üniversitesi, Kimya Bölümü, Sarıçam / ADANA / TÜRKİYE

Powder metallurgy (PM) is a technique for making metal and metal alloy melt-free, with help of

pressure and temperature. Powder metallurgy technology includes various operations after the production

of metal powders, mixing of powders, shaping by pressing in the mold and sintering. The main purpose of

PM is; to obtain the metals as powders and to produce the machine parts by sintering them in the furnaces

after pressing these powders. Pressing is usually done at room temperature, sometimes at high

temperatures. The sintering heat treatment maintains the position of the melt and is carried out at a

temperature [1-3].

The ZAMAK obtained by powder metallurgy is a base metal zinc and an alloy with aluminum,

magnesium and copper alloy elements and is given in Table 1. Since 1991, zinc and its alloys have been

widely used in automotive components such as engine, gearbox systems.

The purpose of this work is to investigate the corrosion behavior of pressed, sintered zinc-based

material that ZAMAK-2 with the addition of titanium and iron. The homogenized powder mixtures were

pressed under high pressure and then sintered at 350 oC under nitrogen atmosphere for 2 hours. Corrosion

behavior of sintered and non-sintered alloys was investigated with electrochemical impedance

spectroscopy (EIS), anodic and cathodic polarization curves, linear polarization resistance (LPR) in 3.5%

NaCl solution. Materials prepared for this purpose was connected as anode and measurements were taken

with three electrode technique. The Pt plate and Ag/AgCl electrode were used as counter electrode and

reference electrode respectively. The surface morphology and chemical composition of the electrodes

were investigated by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX)

and X-ray powder diffraction (XRD) techniques.

NANO YAPILI İMPLANT YÜZEYLERİNİN KOROZYON DAVRANIŞLARI

Ahmet ÇAKIR*1

1Dokuz Eylül Üniversitesi, Müh. Fakültesi, Metalurji ve Malzeme Müh. Bölümü, İZMİR / TÜRKİYE

Nanometre seviyesindeki yüzeylerin yapısı, medikal teknoloji alanındaki ileri düzey uygulamalarda,

malzemelerin fiziksel ve kimyasal özelliklerini geliştirmek için önemli bir potansiyele sahiptir.

Biyomalzemelerin biyolojik ortamlarla etkileşimi büyük ölçüde yüzey özelliklerine bağlıdır. Yeni

dokuların vücuda yerleştirilen implant yüzeyi ile bağlantısı hücresel ve moleküler seviyede

gerçekleşeceği için nanometre boyutundaki yüzey özelliklerinin ayrı bir önemi vardır. Bu öneme binaen

implantın iyileşmesinde kararlı bir kemik-implant teması büyük bir öneme sahiptir ve nano yapılı

yüzeyler özellikle iyi bir osseointegrasyon, protein ve hücre bağlanması için son derece uygundur. Nano

parçacıkların özgül yüzey alanının çok büyük olması sebebiyle bu tip yüzeyler çok büyük bir kimyasal

reaktiviteye sahiptir. Bu artan yüzey aktivitesi, fizyolojik ortamlarda yeni kalsiyum fosfat tabakasını

oluşturmak için değerlendirilebilir.

Yüksek yüzey aktivitesi biyomalzemelerin tanıtıldıkları fizyolojik ortamlarda kolayca

bütünleşmesine sebep olur. Bunun yanında inflamasyona bağlı olarak fizyolojik ortamlarda meydana

gelen değişiklikler sonucu implant yüzeyini koruyan pasif filmler tahrip olabilirler. Pasif filmlerdeki bu

tahribat aşırı yükleme, yorulma ve tribolojik etkilerle de ortaya çıkabilir. İmplatın sağlığı açısından bu

tahribatın kısa zamanda giderilmesi gerekir. Aksi halde protez ömrünün kısalması veya sonlanması söz

konusu olabileceği gibi, aktif hale gelen yüzey gerek vücuda metalik iyon salınımı gerekse korozyon

bakımından faal hale gelecektir. Bunun için de implant yüzeyindeki pasif filmin kısa zamanda kendini

yenileyebilmesi, yüzeyin yeniden pasif hale gelmesi (repassivation) son derece önemlidir. Bu çalışmada

özellikle metalik biyomalzemelerde yüzeyin gerek nano boyuttaki kaplamalarla gerekse malzemenin ana

yapısının nano mikroyapılı olarak üretilmesi ile korozyon davranışlarında sağlanan gelişmeler kapsamlı

olarak ele alınacaktır.

Anahtar Kelimeler: Biyomalzeme, Nanoyapılı kaplamalar, kimasal yüzey aktivitesi, Pasif film, Yeniden

pasifleşme.

INVESTIGATION OF ATTRITION-CORROSION BEHAVIOUR OF NANO-

FILLED DENTAL COMPOSITE MATERIALS

Efe Çetin YILMAZ*1

1Department of Technical Science of Pasinler Vocational School Ataturk University/ ERZURUM /

TURKEY

The aim of this work is to investigation of attrition-corrosion wear behaviour of nano- structured

dental composite materials under in vitro chewing tests. In the conditions recommended by the

manufacturer 10 pieces (12 mm diameter X 2 mm height) were produced from each composite material

(n=5). All test specimens were kept in distill water for 1 week and determined Vicker’s hardness and

surface roughness values before attrition-corrosion wear tests. Then attrition-corrosion wear tests were

performed using a dual-axis computer-controlled chewing simulation (50N, 360.000 chewing cycles 1.0

Hz frequency and 37 °C temperature). For each attrition-corrosion wear test, Al2O3 ball with a diameter

of 6 mm was used as antagonist material. Half of the specimens of each test group were immersed distill

water (about pH=7) and citric acid solution (about pH=3.2). The mean volume loss of all specimens after

the attrition-corrosion wear tests was determined with use non-contact 3D profilometer. In addition to a

random specimen was selected from each test group and Scanning Electron Microscope (SEM) images

were taken for analysis of wear tracks. The surface morphology of both composite material was severely

damaged in immersed citric acid solution under chewing tests. This can be explained by the more damage

to the organic matrix structure of the composite material in citric acid solution than immersed distill

water. Among the composite materials used in this study suggested correlations between Vickers

hardness and attrition-corrosion wear resistance are not significant. The results obtained in this study will

help to understand the effect of the pH value of the third abrasive surface on the composite material in the

three-body wear mechanism.

Key Words: attrition-corrosion wear, composite biomaterial, chewing simulation, hardness.

EFFECT OF THERMAL CYCLING ON CONTACT-WEAR BEHAVIOUR OF

COMPOSITE MATERIALS IN CHEMICAL CORROSION ENVIRONMENT

Efe Çetin YILMAZ*1 1Department of Technical Science of Pasinler Vocational School Ataturk University/ ERZURUM /

TURKEY

The aim of this work is to effect of thermal cycling on contact-wear behaviour of different

composite materials in chemical corrosion environment under in vitro chewing tests. Five specimens of

each composite materials were exposed contact-wear tests using a computer-controlled chewing simulator

(1.2 Hz 50 N bite force loads, 120.000 mechanical cycles, constantly 37 °C temperature and thermal

cycling between 5 and 55°C 5min/cycle 3000 cycles) immersed in artificial saliva. Steatite balls of 6 mm

in diameter were used for each chewing test. All test samples were kept in distill water for 1 week and

determined Vicker’s hardness before contact wear tests. Half of the specimens of each test group were

loaded with a thermal cycle, the other half remaining without thermal cycle loading (n=5). The mean

volume loss of all specimens after the contact-wear tests was determined with use 3D profilometer. In

addition to a random specimen was selected from each test group and Scanning Electron Microscope

(SEM) images were taken for analysis of wear tracks. In this study, all composite materials showed

significantly more volume loss when occurred thermal cycle loading than without thermal cycle contact

wear tests. The result of this study is that the content of the monomer and harder glass structure contained

in the composite material caused more volume loss of the material under in vitro chewing tests.

Key Words: thermal cycle, artificial saliva, chemical corrosion, composite biomaterial, chewing simulation.

INVESTIGATION OF THE CORROSION BEHAVİOURS OF DLC COATINGS

PRODUCED BY PVD TECHNIQUE

Şengül DANIŞMAN1, Tuba DEMİREL*1 1Department of Mechanical Engineering, Engineering Faculty, Erciyes University, KAYSERİ / TURKEY

The biomedical materials used in the body are in contact with living tissues in the human body. In liquid

media in the body, corrosive effects can occur on biomedical material. For this reason, it is necessary to

improve the corrosion properties of biomedical materials such as prostheses and implants used in the

health field and to increase the life expectancy of biomedical materials in the body. Diamond-like carbon

(DLC) coatings used in coating implants and prostheses have gained an important place in other types of

coated materials used in the healthcare sector in recent years. DLC coatings have been found to have high

corrosion resistance, low friction coefficient and good wear resistance. It is important for such coatings

that the coating adheres to the base material.

In this study, properties of DLC coatings obtained by PVD (Physical Vapor Deposition) method

were investigated and corrosion behavior was investigated. The greatest advantage of DLC coatings is

that they are not affected by corrosion and are in harmony with living tissue.

Key Wods: Diamond like coatings (DLC), Corrosion, Adhesion, Biocompatibility, PVD method, Biomedical

materials.

The household drug-related waste and pharmaceutical waste drugs amounted to about 362,000

tones in Green Pharmacist Coop.’s 2017 Turkey report [1]. According to report, a large part of the gross

national income goes to waste. Therefore, the recovery of waste medicines has crucial importance for not

only economy but also for environment. Most of the waste drugs are antibiotics. In order to reduce the

waste disposal-cost indirectly, the compatibility of antibiotic drugs as corrosion inhibitor was studied.

The inhibition effect of antibiotic drug which is entitled “Amoklavin” on the corrosion behavior of mild

steel (MS) was investigated in acidic medium. Amoklavin includes amoxicillin trihydrate

(C16H19N3O5S.3H2O), (AM) and potassium clavulanate (C8H8NO5K) (PC) as a main ingredient. Each

vial contains 1000 mg amoxicillin and 200 mg potassium clavulanate. In this study 5, 10, 25 and 50 ppm

“total AM - PC” concentrations were used.

In order to determine corrosion behavior of MS in absence and presence of AM – PC,

electrochemical impedance spectroscopy and polarization measurements were obtained. Surface

morphology was monitored by scanning electron microscope (SEM). The quantum chemical calculations

were achieved via DFT with the B3LYP/6-311++G (d, p) basis set. The results showed that; inhibition

efficiency (η) increased with increasing concentration. After 1 h immersion, η values were 85.4, 93.5,

95.5 and 96.1% in 0.5 M HCl in the presence of 5, 10, 25 and 50 ppm AM – PC, respectively. The η

decreased with increasing immersion time, for 50 ppm AM – PC, values were 92.9, 92.3, 80.2 and 62.6%

after 24, 72, 120 and 168 hours respectively. Adsorption mechanism of AM – PC molecules on MS

surface obeyed the Langmuir isotherm. According to polarization measurements, AM-PC retard both

anodic and cathodic reactions. The EHOMO and ELUMO were -0.048 and 0.025 eV for AM, -5.025 and

0.107 eV for PC. The higher negative NBO charges were located on N (amine subs.) and S atoms.

Therefore, adsorption may be occurred on amine, and/or S terminal of molecules.

Key Words: Green inhibitor, mild steel, corrosion.

AZ91 Mg ALAŞIMLARINDA Fe TOLERANS LİMİT DEĞERLERİNİN

ARAŞTIRILMASI

Magnezyum (Mg) günümüzde kullanılan metalik malzemeler içinde en hafif olanıdır. Ancak, saf

Mg’un dayanımının düşük olması nedeniyle kullanım alanındaki sınırlamalar değişik alaşımların

üretilmesine yol açmıştır. Mg’un önemli alaşım grupları Mg-Al, Mg-Zn ve Mg-toprak alkali metalleri

(RE) olarak gruplandırılır. Diğer Mg alaşımlar ile karşılaştırıldığında, AZ serisi (Al ve Zn ile

alaşımlandırılan grup) özellikle AZ91 Mg alaşımı (Mg-%9Al-%1Zn) sahip olduğu iyi döküm ve yüksek

mekanik özellikleri sayesinde öne çıkmaktadır.

Magnezyum alaşımlarının korozyon dayanımını olumsuz etkileyen Fe, Si, Cu ve Ni gibi empürite

elementleri her zaman bulunur [1,2]. Fe empürite elementi, küçük bir miktar bile olsa, Mg alaşımlarının

korozyon direncini önemli ölçüde azaltabilir [1]. Özellikle, endüstriyel uygulamalar için Fe’nin tolerans

limit değerlerinin bilinmesi maliyet/kalite oranı açısından son derece önemlidir. Literatürde Fe’nin

olumsuz etkisi ile ilgili tolerans limit değerleri saf Mg için bulunmasına rağmen [3,4], AZ91 alaşımları

için bu bilgi sınırlıdır [5]. Diğer taraftan, alaşım elementlerinin [6-8] yanısıra katılaşma hızının [9-11] ve

üretim yöntemlerinin [12] de mikroyapıyı önemli ölçüde etkilediği ve bunlara bağlı alaşımın korozyon

davranışları üzerinde ciddi etkiler yaptığı bilinmektedir .

Bu çalışmada, aynı şartlarda üretilmiş (benzer katılaşma hızı ve benzer kimyasal bileşimde) farklı

Fe içeriğine sahip AZ91 alaşımlarının korozyon davranışları - Fe tolerans limit değeri arasındaki ilişki

değerlendirilmiştir. Korozyon davranışları %3,5 NaCl çözeltisinde, ağırlık kaybı ve potansiyodinamik

polarizasyon test yöntemleri kullanılarak değerlendirilmiştir. Sonuçlar, AZ91 alaşımı Fe limit değerinin

% 0,05 olduğunu bu değerden sonra korozyon kaybının eksponansiyel olarak arttığını göstermiştir.

Anahtar Kelimeler: AZ91Mg alaşımı, Mikroyapı, Korozyon.

AZ91 Mg ALAŞIMININ KOROZYONUNDA Fe’nin ZARARLI ETKİSİNİN

AZALTILMASINDA YENİ BİR YAKLAŞIM

Şennur CANDAN, Serdar ÇİM, Seren EMİR, Ercan CANDAN*

Bilecik Şeyh Edebali Üniversitesi, Makine Mühendisliği Bölümü, BİLECİK / TÜRKİYE

Magnezyumun (Mg) sahip olduğu en önemli özelliği ağırlık olarak alüminyumdan %35 ve

demirden %75 daha hafif olmasıdır. Ancak, saf Mg’un dayanımının düşük olması nedeniyle kullanım

alanındaki sınırlamalar değişik alaşımların üretilmesine yol açmıştır. Mg’un önemli alaşım grupları Mg-

Al, Mg-Zn ve Mg-toprak alkali metalleri (RE) olarak gruplandırılır. Diğer Mg alaşımlar ile

karşılaştırıldığında, AZ serisi (Al ve Zn ile alaşımlandırılan grup) özellikle AZ91 Mg alaşımı (Mg-%9Al-

%1Zn) sahip olduğu iyi döküm ve yüksek mekanik özellikleri sayesinde öne çıkmaktadır. Özgül

mukavemet değerlerinin yüksek olmasından dolayı AZ serisi Mg alaşımları otomotiv endüstrisinden

elektronik ve uzay endüstrisi gibi birçok mühendislik alanında kullanım alanlarına sahip olmakla birlikte

düşük toksik özelliği nedeniyle biyo-uyumlu ve biyo-bozunur bir metalik biyomalzeme olarak, ortopedik

implant uygulamalarında plaka ve vida yapımında potansiyel implant malzemeler olarak kullanılması da

son yıllarda ilgi çekmektedir [1-10].

Mg alaşımlarının korozyon direnci, Fe empürite oranınına oldukça duyarlıdır [11-15]. Çok küçük

değerler dahi alaşımın korozyon direncini azaltmaktadır [11,15]. Literatür araştırmaları [16-19] AZ serisi

Mg alaşımına Ti ilavesi ile alaşımın mekanik dayanım ve korozyon direncinin etkin bir biçimde

artırdığını göstermiştir. Mekanik dayanım ve korozyon direncindeki artış, mikroyapıdaki β fazının Ti

ilavesi ile parçalı ayrışmış ötektikten tam ayrışmış ötektiğe dönüşmesine dayandırılmıştır [16,17]. Ancak,

Fe’nin AZ91 Mg alaşımlarının korozyonu üzerindeki zararlı etkisini azaltmada Ti’un rolü ile ilgili

çalışma bulunmamaktadır.

Bu çalışmada farklı Fe içeriğine sahip Ti ile mikro alaşımlandırılmış AZ91 alaşımlarının korozyon

dayanımlarında Ti’nin rolü araştırılmıştır. Korozyon davranışları %3.5 NaCl çözeltisinde, ağırlık kaybı ve

potansiyodinamik polarizasyon test yöntemleri kullanılarak değerlendirilmiştir. Sonuçlar, Ti’nin AZ91

alaşımlarında çok yüksek Fe empürite oranlarında (% 0.1 Fe) dahi korozyon direncini kayda değer oranda

arttırdığını göstermiştir.

Anahtar Kelimeler: AZ91 Mg alaşımı, Mikroyapı, Korozyon.

Recently, Pipeline corrosion is a major problem facing many oil and gas industries today because of

the enormous downtime associated with corrosion related failures. In this study, the effect of tempering

temperature (200, 400 and 500 °C) on the corrosion behavior of American Petroleum Institute (API) N80

steel in albian water at different gradient temperatures (0, 3, 9 and 16 °C) were investigated using X-ray

diffraction (XRD), the electrochemical measurements combined with hardness test. XRD patterns have

shown that the API N80 steel samples crystallize in ferrite type structure with a strong (110) orientation.

We remarked that all samples the N80 are a nanometric grain size, the values of grain sizes given in the

range from 211 to 450 Å. Corrosion rates of samples are correlated with structural changes (grain size,

strain) in samples with increasing tempering temperature. Steel N80 with higher tempering temperature

exhibited excellent corrosion resistance with lower corrosion current density. The distinction of corrosion

resistance can be attributed to increased grain sizes and decreased residual stress and hardness.

Key Words: API N80, residual stresses, tempering temperature, corrosion, hardness

Recently, magnesium alloys become very attractive biomaterials as using biodegradable stent [1].

However, the corrosion rapid of magnesium limit their function [2-4]. In this study, AZ91 alloy was

cryogenic treated at -196oC for 48h and corrosion performance was evaluated versus AZ91 untreated. The

samples were immerged in 0.9% NaCl solution (simulating a human body fluid) and were tested by

electrochemical methods such as the open circuit potential measurement (OCP), the potentiodynamic

polarization, the electrochemical impedance spectroscopy (EIS) and the cyclic voltammetry (CV). In

general, the results obtained for the electrochemical studies shows that the cryogenic treated AZ91 sample

hold superior corrosion resistance when compared to the former sample. After 2 hours of OCP test,

treated AZ91 was slightly more noble than untreated AZ91 (figure 1). The slopes at the passivation zones

were steeper for the cryogenic treated sample and the corrosion potential of the cryogenic sample was

also lower than that of the former sample as determined by using the polarization method. A more aced

loop was displayed for the cryogenic treated sample when the EIS was carried out at a higher frequency,

also indicating that the later sample possess higher corrosion resistance compared to the former sample.

İyi bilindiği üzere; magnezyum (Mg) ve alaşımlarının günümüz mühendislik uygulamalarında

yaygın olarak kullanılamamasının başlıca iki sebebi bulunmaktadır. Bunlar; pek çok durumda arzu edilen

mekanik özellikleri karşılayamaması ve korozyona karşı yüksek duyarlılıklarıdır. Mekanik özelliklerin

artımı için Mg’nin seramik partiküller ile takviye edilmesi günümüzde en sık kullanılan yöntemlerin

başında gelmektedir. Ancak, özellikle üretimde çoğu zaman döküm tekniklerinin tercih edilmesi nedeni

ile bileşenlerin maruz kaldığı yüksek sıcaklıklar istenmeyen arayüzey reaksiyonlarının oluşmasına ve sert

seramik takviyeler nedeniyle de sünekliliğin arzu edilen seviyelerin altında kalmasına neden olmuştur. Bu

problemlerin üstesinden gelmek için alternatif olarak TiNi alaşımının kullanılması dikkat çekicidir [1].

Yapılan çalışmalar Mg’un üretim yöntemine, metalürjik ve alaşım yapısına bağlı olarak tane boyutunun

ve faz dağılımının korozyon özelliklerini büyük ölçüde değiştirdiğini göstermiştir [2], [3]. Bu çalışmada;

hacimce %5-25 arası değişik oranlarda TiNi ile takviye edilmiş saf Mg matrisli kompozitler sıcak

presleme tekniği ile başarılı bir şekilde üretilmişlerdir. Özellikle otomotiv endüstrisi için aday bu yeni

malzemelerde yukarıda sayılan sebeplerden dolayı korozyon davranışının bilinmesi büyük önem arz

etmektedir. Bu amaçla, üretilen kompozitlerin korozyon duyarlılıkları üzerine takviye fazı hacim oranının

etkisi %3.5 NaCl çözeltisi içerisinde potansiyodinamik polarizasyon (PDS) tekniği ile araştırılmıştır.

Elektrokimyasal değerlendirmeler ise Tafel ekstrapolasyon yöntemi ile yapılmıştır. Kompozitlerin

korozyon öncesi/sonrası metalografik incelemeleri, taramalı elektron mikroskobu (SEM) ve optik

mikroskop (OM) kullanılarak gerçekleştirilmiştir. Elde edilen bulgular karşılaştırmalı ve sistematik bir

yaklaşımla bildiri detaylarında irdelenmiştir.

Magnezyum ve alaşımlarının otomotiv endüstrisindeki kullanımı her geçen gün artmaktadır. Taşıt

ağırlığının önemli bir kısmını oluşturan motor bloğu, silindir kapağı, vites kutusu ve diferansiyel kutusu

gibi güç aktarma organlarında önemli miktarda kullanım alanı bulacağı bileşenleri olacağı

öngörülmektedir [1]. Fakat magnezyum ve alaşımlarının yüksek sıcaklık mekanik özelliklerinin ve

korozyon dayanımlarının düşük olması bu alanlardaki kullanımlarını sınırlamaktadır. Seramik partikül ve

fiberler ile güçlendirilmiş magnezyum matrisli kompozitlerde mukavemette belirgin bir artış gözlemlense

de matris takviye ara yüzeyinde kimyasal reaksiyonlar sonucu oluşan ikincil fazlar ve yetersiz

ıslatılabilirlik sünekliğin önemli oranda düşmesine neden olmaktadır [2]. Bu olumsuzluklardan dolayı

magnezyum ile benzer fiziksel özelliklere sahip metalik malzemeler takviye materyali olarak

kullanılmaktadır. Bunlar arasında TiNi alaşımları sahip oldukları üstün özellikler nedeniyle ön plana

çıkmaktadır. Bu çalışmada AZ91D magnezyum alaşımı TiNi ile farklı oranlarda takviye edilerek belirli

süre ve sıcaklıklarda sinterlendi (tek eksenli sıcak presleme tekniği kullanıldı). Üretilen kompozitlerin

korozyon davranışı % 3.5 NaCl çözeltisi içerisinde potansiyodinamik polarizasyon (PDS) yöntemi ile

belirlendi. Korozyon akımı ve potansiyeli Tafel ekstrapolasyonu metodu ile tespit edildi. Kompozit

malzemelerin elektrokimyasal deneyler sonucu elde edilen korozif özellikleri korozyon öncesi ve sonrası

yapılan taramalı elektron mikroskobu (SEM) ve optik mikroskop (OM) görüntüleri ile desteklendi.

Anahtar Kelimeler: Magnezyum, Kompozit malzemeler, TiNi şekil bellekli alaşımlar, Toz metalürjisi, Korozyon.

In this study, quality of the yarns against the drum corrosion behavior was studied. Drum is a

machine element in the ring spinning unit.

In ring spinning machines operating at high speeds of production, corrosion between machine parts

and the fiber-yarn is inevitable. Regarding this reason, some problems arised at the quality values of

produced yarns such as low strength values, hairiness and yarn unevenness.

Unevenness, hairiness and strength tests of these yarns were performed. It was found that the

unevenness, strength and hairiness test values of the yarns that are produced with new drums were higher

than the yarns that are produced with corroded drums.

In addition, the changes of the physical corrosion on the drums in these machines were examined

morphologically at scanning electron microscope. Qualitative and quantitative analysis were carried out

on an EDX spectrometer. When the new drum and the corroded drum were examined by Scanning

Electron Microscope, it was seen that the structures are similar and contain carbon, nickel, oxygen and

phosphorus but at the corroded parts of the drums, nickel-plated structures were turned to iron.

Key Words: Ringspinning, friction, abrasion, corrosion, SEM-EDX, yarn quality parameters.

/ TÜRKİYE

Endüstriyel uygulamalarda yaygın olarak kullanılan östenit çeliklerin yüksek korozyon dayanımı

sulu çözeltilerde yüzeyinde oluşan pasif oksit filmine bağlıdır. Yüksek kararlılığa sahip oksitler ve oksi-,

hidroksit bileşikleri pasif filmin en dış yüzeyinde yer alırlar. Pasif filmin direnci paslanmaz çeliğin maruz

kaldığı ortamlara ve çeliğin bileşimine göre değişmektedir. Klorür gibi agresif iyonlar, bölgesel olarak

pasif tabakaya zarar vererek çukurcuk korozyonuna neden olmakta ve korozyonu hızlandırmaktadırlar.

Yaygın olarak kullanılan azol ve tiol gibi organik inhibitörler metal yüzeyinde film oluşturarak korozyonu

yavaşlatmaktadırlar. Ayrıca molibdat, tungstat gibi anodik inhibitörler, pasif filmin hasar görmesi ile

oluşan metasatable çukurcukların süratle onarılmasını sağlarlar.

Bu çalışmada 3-Amino-5-metiltiyo-1H-1,2,4-triazol (AMTA) organik bileşiğinin, sodyum molibdat

ile uygun kombinasyonu yapılarak %3 NaCl çözeltisi içinde 304 çeliğinin korozyonuna karşı inhibisyon

etkinlikleri incelenmiştir. Triazol türevlerinin metal üzerinde oluşturduğu adsorpsiyon tabakası agresif

iyonların yüzeye ulaşmasını önlerken, molibdat katkısı başlangıç aşamasındaki çukurcukların tamir

edilmesini sağlamaktadır. Metal yüzeyinde oluşan koruyucu tabakanın dayanımı elektrokimyasal

teknikler ve yüzey analiz yöntemleriyle araştırılmıştır.

Anahtar Kelimeler: 304 çelik, çukurcuk korozyonu, sodyum molibdat, 3-Amino-5-metiltiyo-1H-1,2,4-triazol.

Titanyum ve alaşımları sahip oldukları mükemmel mekanik özelliklerden dolayı sanayi ve

endüstrinin hemen hemen tüm alalarında kullanılmaktadır. Biyomalzeme olarak ise vücut içerisinde

implante edilebilmektedir. Ancak yüzeylerinde bulunan pasif oksit tabakası aşırı agrasif ortamlarda bu

malzemeyi koruyamaz ve hızla korozyona uğramasına sebep olmaktadır. Bu dezavantajının minimize

edilmesi adına yüzey işlemleri uygulanabilmektedir. Son yıllarda özellikle hafif malzemeler üzerine

Mikro ark oksidasyon (MAO) yöntemiyle büyütülen oksit tabakalar bu malzemeler üzerinde de

büyütülmekte ve onları korozyon, aşınma ve bu iki mekanizmanın sinerjisi olan tribokorozyon

mekanizmasına karşı korumaktadır. Bu çalışmada Ti6Al4V alaşımı üzerine MAO yöntemiyle büyütülen

oksit tabakasının vücut sıvıları içerisindeki tribokorozyon özellikleri incelenmiş ve büyütülen kaplamanın

etkisi vurgulanmıştır.

Anahtar Kelimeler: Biyomalzeme, MAO yöntemi, Korozyon, Tribokorozyon ve Aşınma.

Titanyum ve alaşımlarının, sahip oldukları düşük ağırlık ve yüksek mukavemet onların gerek

endüstriyel alanda gerekse dekoratif uygulamalar gibi birçok alanda kullanımını giderek artırmaktadır.

Bununla birlikte bu alaşımların aşınma ve korozyona karşı zayıf yüzey özellikleri göstermeleri onların

agresif alanlardaki kullanımını sınırlandırmaktadır.

Günümüz şartları ve teknolojisinin bir gereksinimi olarak; ağır şartlar altında çalışan makine

elemanlarının sürtünme ve aşınmaya dirençlerini daha da artırılması ihtiyacı duyulmuştur. Bu bağlamda

ise DLC (elmas benzeri karbon) gibi yeni tür kaplamaların gelişmesi ve sanayide uygulamaya girmesi söz

konusu olmuştur.

Bu çalışmada ise Ti6Al4V alaşımı üzerine CFUBMS (kapalı alan manyetik alanda sıçratma)

yöntemi ile Ti-DLC kaplaması büyütülmüştür. DLC kaplanmış Ti6Al4V alaşımlarının yapısal, mekanik,

aşınma, korozyon ve tribokorozyon davranışları SEM, XRD, Pin-on-Disk, potansiyostat ve çizme test

cihazları kullanılarak analiz edilmiştir.

Anahtar Kelimeler: DLC kaplamalar, Ti 6Al4V alaşımı, tribokorozyon.

Birçok yerde geniş kullanım alanına sahip olan paslanmaz çeliklerin yüzeylerinin ıslanabilme

özelliklerini değiştirerek onlara fonksiyonel özellik kazandırmak, son yıllarda çok yaygınlaşmıştır.

Özellikle implant malzemelerde, doku-protez arayüz stabilitesinde yüzey topografisinin önemli

olduğunun belirlenmesi, bu konudaki çalışmaları arttırmıştır. Yüzey topografisini istenilen yönde

değiştirerek ortamdaki mikroorganizmaların yüzeye yapışma ve yapışamama kabiliyetleri de

geliştirilmektedir. Lazer yüzey tekstürleme, yüzey ıslanabilirliğinin modifikasyonu için yeni kullanılmaya

başlayan bir teknik olup, farklı mikro/nano ölçekli yüzey yapılarının oluşturulmasına olanak

sağlamaktadır.

630 kalite paslanmaz çelikler, cerrahi makas üretiminde kullanılmaktadır. Cerrahi operasyonlar

sırasında, uzun süre vücut sıvılarıyla temas halinde bulunan kontamine tıbbi cihazlar ve/veya cerrahi

aletler ile bu materyallerin yüzeylerine tutunan mikroorganizmalar arasındaki etkileşimler, bireyler için

ciddi enfeksiyon riski taşımaktadırlar. Cerrahi operasyonlarda kullanılan cihaz ve aletlerin yüzeylerinin

kontaminasyonunda yaygın olarak rapor edilen bakterilerden Escherichia coli, insan vücudu veya

hayvanlar için her zaman zararlı olmasa da, virülans faktörleri sebebiyle çeşitli enfeksiyonlara yol

açabilmektedir [1, 2]. Bu nedenledir ki son yıllarda, cerrahi aletlerde tutunmayı engelleyici anti-bakteriyel

yüzey özelliklerine sahip metallerin kullanımına odaklanan çalışmalar artmıştır. Yapılan araştırmalar,

mikron, mikronaltı ve nano özellikler ile yapılandırılan yüzeylerin, aynı ortamdaki pürüzsüz yüzeyi ile

karşılaştırıldığında %90'a varan oranlarda bakteri yapışmasını önemli ölçüde azalttığı bildirilmiştir [3].

Bu çalışmada, lazer ile desen kazandırılmış 630 kalite paslanmaz çeliğin yüzeyine (LY), E. coli

bakterisinin tutunma yeteneği incelenmiş ve lazerle işlem görmemiş düz yüzey (DY) ile karşılaştırması

yapılmıştır. LY’nin ıslatma açısı sesil damla yöntemi ile ölçülmüş ve taramalı elektron mikroskobu

(SEM) ile incelenmiştir. Bakterinin yüzeylerle ilişkilerinin araştırılması amacıyla, hem LY hem de DY

kuponlar laboratuvar ölçekli bir test sisteminde 48 saat boyunca E. coli kültürüne maruz bırakılmıştır. LY

ve DY kuponlardan elde edilen biyofilm tabakalarından E. coli sayımı yapılmış ve hücre dışı polimerik

madde (EPS) içeriğindeki toplam karbonhidrat miktarı değerlendirilmiştir. LY ve DY kuponların

yüzeylerindeki biyofilm oluşumlarındaki farklılıklar SEM ile araştırılmıştır. Ayrıca, metalin korozyon

davranışı potansiyodinamik eğriler ile incelenmiştir.

Deney sonucunda E. coli’nin, LY kuponlarına, DY kuponlarından daha geç tutunduğu ve sesil

bakteri sayısının daha düşük olduğu belirlenmiştir. Ayrıca, LY kuponlarındaki karbonhidrat miktarının

DY kuponlarından anlamlı derecede daha yüksek olduğu saptanmıştır (p <0.01). Aynı zamanda SEM

mikrograflarında, LY kuponların yüzeyinde daha farklı bir tabakalaşmanın olduğu gözlenmiştir. Bu

veriler, bakterinin hidrofobik yüzeye tutunabilmek için daha fazla EPS salgıladığının ve strese bağlı

olarak tabakalaştığının bir göstergesi olarak değerlendirilebilmektedir.

MICROBIOLOGICALLY INDUCED CORROSION BEHAVIOR OF N-80 STEEL

BY GRAVIMETRIC METHOD

Several microbial communities with diverse metabolic activities have been found to live

underground, including a large number of petroleum deposits. Microorganisms found in petroleum

reservoirs can cause microbiologically induced corrosion (MIC) by inducing localized changes in

aqueous media (such as changing electrolyte concentration, components, pH and oxygen concentration).

MIC is known to cause corrosion of oil pipelines and storage tanks leading to serious economic loses. It

has been reported that about 20% of all corrosion problems in the oil and gas industry are formed by

microorganisms.

It was aimed to detect microbiological corrosion behavior of N80 steel, which is often used as

tubing material in oil wells, in produced water by weight loss method. In order to detect MIC, two

separate laboratory scale systems were established, one for testing and the other for control. In the test

system, N80 steel coupons were exposed to the produced water taken from Adıyaman oil field over 120 d.

The control system was established with sterile produced water simultaneously with the test system. Both

of the systems were set up in duplicate. For the weight loss measurement, the coupons were removed

from the systems at specific time intervals and the weight loss was calculated. The surface of coupons

was investigated by scanning electron microscopy (SEM).

The results indicate that N-80 steel was microbiologically corroded. As matter of fact, SEM

photographs validated the presence of microorganisms among the corrosion products.

Key Words: N80 mild steel, Microbiologically induced corrosion (MIC), Weight loss measurements.

Mild steel is an illustrious material used in different industries and highly predisposed to corrosion

in acid medium. As a result the biggest problem that we face in using of these kinds of materials is

corrosion. Inhibitor application is both economical method and one of the most practical ways [1-4].

Electrochemical measurements were performed in 0.5 mol L-1 HCI solution in the inhibitor free

and in the presence of various 2,4-Diamino-6- Phenyl-1,3,5 triazine (DPT) concentrations. The different

concentrations of inhibitor were obtained by diluting the correct amounts of this solution to obtain 10.0,

5.0, 1.0, and 0.5 mmol L-1 solutions. Corrosion tests were performed in a three-electrode cell closed to air

under stagnant conditions at 25○C, which was controlled by a thermostat. An Ag/AgCl electrode was

used as a reference electrode, along with a platinum sheet as a counter electrode.

In the present work, the corrosion inhibition efficiency of a newly DPT, on the mild steel in

hydrochloric acid solution was investigated utilizing linear polarization resistance, electrochemical

techniques and SEM method. DPT exhibits good inhibitive properties for mild steel corrosion in 0.5 M

HCl solution and the efficiency of inhibition increased with increasing inhibitor concentration. The results

indicated that DPT had good inhibition efficiency.

Stainless steel (AISI 304) is easily accessible, easily shaped and easy to produce. These advantages

allow the AISI 304 steel to be used in a wide variety of applications. For this reason, it is the most

commonly used type of stainless steel in the world. From the food industry to the petroleum industry,

from kitchenware to heat exchangers, it has many uses. However, like other stainless steels, it is

inevitable to experience corrosion in AISI 304 stainless steel. There are many methods for corrosion

prevention studies. However, the electrochemical coating method is very highly preferred method of all

of them in recent years, since the desired coating thickness can be achieved and the monomer solutions

can be prepared in desired amounts and in a rapid manner. Polymers prepared by this method are used in

many areas from corrosion protection to rechargeable batteries to prevent corrosion [1].

In this study, poly (indole-co-methyl acrylate) was coated on AISI 304 stainless steel by cyclic

voltammetry technique. Copolymer was synthesized on stainless steel electrode surface in 0.1 M

monomer containing LiClO4-acetonitrile. The copolymer films were characterized by FT-IR, SEM and

EDX. Corrosion performance studies of the electrodes were made in 3.5% NaCl solution.

Corrosion is one of the main problems of industrial process which used acid solution such as the

pickling and industrial acid cleaning. Corrosion leads to great losses as financial losses and environmental

pollution [1]. Protection of metals such as mild steel (MS) against the corrosion is important for

economic, security and resource conservation. It is impossible to completely prevent corrosion although it

is possible to reduce losses significantly. One of the simplest methods is inhibitors for protection of metal

against the corrosive media. Inhibitors can slow down the reaction between metal and corrosive

environment [2].

Adsorption of an inhibitor on the metal surface can be explained with the different ways. First of

them is defined as electrostatic force that consist of between ionic charges on the adsorbed species and the

electric charge at metal/ solution interface. Others can be indicated as interaction of unshared electron

pairs in the molecule with the metal, interaction π-electrons with the metal and combination of

electrostatic force and interaction of π-electrons with the metal [3, 4].

In this study, the effect of Sulfanilamide was studied on the MS corrosion in 0.5 M HCl by

electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic

polarization measurements. The electrochemical measurements showed that the inhibitor compounds

form a good protective film on the mild steel surface.

Corrosion is known as a serious and challenging problem faced by various industries. The organic

inhibitors are widely used for prevention of acid corrosion in various industrial processes such as

pickling, descaling, oil well acidizing, and cleaning, etc. Most well-known acid inhibitors are organic

compounds containing nitrogen (N-heterocyclic) ‚ sulfur‚ oxygen atoms, long carbon chain or aromatic

groups. Using of organic inhibitor is an economical and practical method to prevent the metal corrosion

[1-4].

In this study, effect of 4,6-diamino-2-hydroxy-1,3,5-triazine (DHT) on mild steel corrosion was

studied in 0.5 M HCI solution by means of linear polarization resistance, electrochemical impedance

spectroscopy (EIS) and polarization measurements. The surface morphology of mild steel was examined

with scanning electron microscopy (SEM) in the absence and presence inhibitor. DHT exhibits good

inhibitive properties for mild steel corrosion in 0.5 M HCl solution and the efficiency of inhibition

increased with increasing inhibitor concentration. The adsorption of DHT on the mild steel surface obeys

the Langmuir isotherm.

Betonarme yapı sistemi, çok farklı çevresel etkiler altında kullanılabilmesi ile birlikte, beton ve

donatı açısından önemli dayanıklılık sorunlarını da beraberinde getirmektedir. Gerek betonun bozulma

sürecinin, gerekse içindeki donatının korozyon sürecinin doğru bir şekilde değerlendirilmesi, yapıların

emniyetli servis ömürleri açısından büyük önem arz etmektedir [1].

Korozyon çelik konstrüksiyonlu tüm yapılarda kaçınılmazdır. Ancak etkileri ve korozyon sonucu

oluşan maddi kayıplar önceden alınacak tedbirlerle en aza indirilebilir. Yatırım maliyetini artıran bu

tedbirler, yapının işletme ömrünü artırarak ve bakım aralığını azaltır ve uzun vadede yapının ekonomik

olmasını sağlar. Korozyondan korunmak için korozyonu tanımak önemlidir. Etkin bir koruma sağlayarak

korozyon kayıplarını mümkün olduğu kadar azaltmak için; mühendislerin korozyonu tanıması,

nedenlerini incelemesi, mevcut denetim tekniklerini bilmesi gerekir [2].

korozyon davranışı incelenmiştir. Bu inceleme 3 elektrot yöntemi kullanılarak elektrokimyasal ölçümlerle

yapılmıştır. Bu ölçümler ile yumuşak çelik numunenin açık devre potansiyelleri, Nyquist eğrileri ve Tafel

eğrileri elde edilerek incelenmiş ve sonuçları oransal olarak kıyaslanmıştır.

Corrosion, is one of the most important factor to achieve in completing the service life of reinforced

concrete structures, also cause significant losses in energy damping capacities of structures. This loss is

related with corrosion level of structure. Depending on the level of corrosion, cracks in the concrete cause

significant reductions in concrete strength and the adherence between concrete and reinforcement.

Therefore, it is very important to detect the loss in the strength and stiffness of the structures for the

structure close to end of its services life. In this study, the reinforced concrete column designed in ½

geometrical scale was subjected to accelerated corrosion test for 26.5 days under 1 ampere constant

current (Figure 1). As a result of the experiment, weight loss and strength reductions was obtained. Loss

of strength in reinforcement due to corrosion damage was obtained with experimental procedure. Loss of

cross section and reduction of compressive strength of concrete were obtained with empirical formulas in

the literature [1]. Thanks to this data, 3 different scenarios applied on a sample building in Hatay

province. Static pushover analyzes of the sample building designed in accordance with the regulations

were carried out with Sap 2000 program under the specified corrosion scenarios . The load-displacement

curves obtained by the scenarios are compared with the curves of the reference building. As a result of the

comparisons, it was observed that corrosion damage caused significant loss in horizontal load carrying

capacity of the building (Figure 2). The corrosion scenarios show that corrosion in columns or beams

changes collapse modes of the structure.

SURFACE CORROSION OF AUSTENITIC STAINLESS STEEL IN THE

CONTAMINATED PHOSPHORIC ACID

Y. Kerroum*1, A. Guenbour1, A. Bellaouchou1, M. Tabyaoui1 1Mohammed V University, Chemistry Department, Rabat / Rabat / MOROCCO

The phosphoric acid manufacturing is an essential industry for many application domains. The

stainless steels are widely used in this industry for their good properties against the destructive

environment, but the presence of various impurities as halides increase the corrosion of the material [1-2].

In this sense, the investigation of austenitic stainless steel corrosion behavior was evaluated in the

presence of the fluoride ions.

This research is carried out by the use of stationary and transient electrochemical methods, and

Mott-Schottky analysis. The electrochemical methods revealed a change in the anodic parameters and the

protection of the material was provided by the formation of inner and outer layers become less protecting.

The curves of the Mott-Schottky analysis explained that in the presence of fluoride ions, the

semiconductor of the barrier film consists of an n-type (Figure 1).

Figure 1. The Mott-Schottky plots of passive films formed on stainless steel in polluted phosphoric acid solution

without and with the fluoride ions.

Regarding the Mott-Schottky diagram, the addition of 2 % of fluoride ions decreases the

capacitance values and exhibits a disappearance of p-type capacitance response.

Key Words: Corrosion, phosphoric acid, stainless steels, fluoride ions, semiconductor film.

CORROSION BEHAVIOR OF DUAL-PHASE 600 AND 800 STEELS IN %3.5

NaCl ENVİRONMENT

Nuri SEN1, Hüsnü GERENGI1, İlyas UYGUR*1, Ertuğrul KAYA1 1Düzce University, Engineering Faculty, Corrosion Research Laboratory, DUZCE / TURKEY

Improved engine efficiency, weight reduction, minimized frictional losses and renewable energy

use in the automotive and transport industries can have a significant effect on CO2 and NOx emissions.

One way of achieving a lighter vehicle by using Ultra High Strength Steels (UHSS) in vehicle body

structures there are lower in thickness or by using lightweight materials such as aluminium, magnesium

or polymer matrix composites. Some UHSS steels like DP 600 and DP 800 are often used for car bodies,

LPG tanks, door beams, reinforcement components, crash structures and longitudinal cross members as

well as for light weight seat structures in cars and trains [1-3].

In this study, corrosion properties of dual-phase 600 and 800 steels in a 3.5% NaCl environment

were evaluated using Electrochemical Impedance Spectroscopy (EIS) and weight loss methods. Although

the samples were quite similar to each other in their compositions it was observed that the very small

differences had changed the corrosion mechanism. For this reason, the calculated charge transfer

resistance (Rct) of the DP 800 in 3.5% NaCl environment was 51% greater than that of the DP 600

sample. This finding was confirmed by weight loss method results and SEM-EDAX analysis.

FARKLI HALAT TİPLERİNİN KOROZYON HIZLARININ TAFEL

EKSTRAPOLASYON YÖNTEMİ İLE DENEYSEL OLARAK ELDE EDİLMESİ

Haşim Fırat KARASU*1, Mine DEMİRSOY1 1Dokuz Eylül Üniversitesi, Makine Mühendisliği Bölümü, Buca / İZMİR / TÜRKİYE

Çelik tel halatlar, yüksek neme ve deniz tuzuna maruz kalan limanlardaki krenlerde, gemilerde, açık

denizlerdeki petrol platformlarında sıklıkla kullanılmaktadır. Eğer bu ortamlarda oluşan korozyonun halat

üzerindeki etkisi göz ardı edilirse yüksek yük taşıma kapasitelerindeki bu elemanlar için ciddi derecede

bir risk faktörü ortaya çıkmaktadır. Bunun önlenmesi için öncelikle korozyonun halatta meydana getirdiği

etkileri iyi bir şekilde gözlemlemek gerekmektedir.

Literatür incelendiğinde yük taşıma halatlarının korozyon davranışlarının incelenmesinde korozyon

sonucunda malzemedeki kayba veya çaptaki azalmaya bakıldığı gibi mekanik deneylere, elektrokimyasal

yöntemlere veya yüzey karakterizasyonuna başvurulmuştur. Bu çalışmada bunlardan elektrokimyasal bir

yöntem olan Tafel eksrapolasyon yöntemi incelenmiştir.

Tafel ekstrapolasyon yönteminde amaç, malzemelerin korozyon hızının gerçeğe en yakın şekilde

belirlenmesidir. Elektrokimyasal korozyon deneyleri için liman ve gemilerde sıklıkla kullanılan Standart,

Seale ve Warrington Seale tipleri belirlenmiş ve bunlar kendir ve çelik özlü olmak üzere ayrı ayrı

incelenmiştir. Solüsyon olarak %3,5 NaCl çözeltisi ve üçlü elektrot sistemi kullanılarak hazırlanan

deneyler sonucunda 6 farklı halatın Tafel eğrileri bulunarak buradan korozyon akım yoğunluğu (Icorr),

korozyon potansiyeli (Ecorr) ve korozyon hızı değerleri tespit edilmiştir.

Yapılan çalışma ile halatların korozyon hızı değerlerine bağlı olarak korozyon dayanımları

karşılaştırılmıştır. Sonuç olarak, korozyon potansiyelinin yüksek olduğu açık deniz, deniz kenarları gibi

yerlerde kullanılan yük taşıma sistemlerinde kendir ve çelik özlü olarak kullanılması uygun olan halatlar

belirlenmiştir.

Anahtar Kelimeler: yük taşıma halatları, tafel ekstrapolasyon yöntemi, korozyon hızı, üçlü elektrot sistemi.

MICROBIALLY INDUCED CORROSION BY MANGANESE OXIDIZING

BACTERIA

Manganese (Mn) is an abundant transition metal that can be readily transformed into different forms

under physical-chemical conditions and plays important roles in elemental biogeochemical cycles. The

oxidized form of Mn, manganese oxidies, are some of the strongest oxidants naturally found in the

environment. Bacteria and some fungi are known to enzymatically catalyze the oxidation of soluble Mn

to Mn oxide minerals faster than abiotic Mn-oxidization in nature [1]. Recently, gaps in literature on

manganese oxidizing bacteria (MOB), their manganese oxidation mechanisms and the potential corrosion

risk on metalic materials have gained in importance. It was suggested that Mn oxides produced by MOB

promote pitting and crevice corrosion through a combination of electrochemical effects caused by

galvanic coupling between Mn oxide deposits and the metallic surface in industrial water systems such as

water distribution systems of refining plants, cooling water lines of sewage treatment plants and

hydroelectric power plants. It was reported that the most common corrosion issues for hydroelectric

power plants have been seen in the components such as turbine blades, runner rings and wicket gates [2].

As a matter of fact, it was informed that there was severe corrosion problem in wicket gates made

of martenzitic stainless steel in a hydroelectic power plant located in Elazığ/Turkey. Also it was claimed

that MOB were the main reason of this corrosion formation. To validate this prediction, biofilm from

wicket gates` surface and water samples from spiral casing and lake were taken from the hdyroelectic

power plant and, the presence and density of MOB were investigated in the samples.

MOB were detected in all samples which were obtained. The number of the MOB in biofilm and

the water samples from spiral casing and lake were determinated as 5.5x105 cfu/cm2, 5.5x103 cfu/ml and

2.2x103 cfu/ml, respectively. In fact, presence of MOB and detecting them in high number may not be the

evidence of that MOB is the only responsible bacterial group from the present corrosion. As a matter of

fact, during sampling procedure, morphologically dissimilar corrosion products that can belong to other

bacterial groups responsible from corrosion were also observed. Therefore, corrosion effect of MOB on

martensitic stainless steel needs to be detected under standart laboratory conditions.

It is well known that surfaces immersed in natural seawater become colonized by microorganisms

and cause biofilm formation that leads to the modification of local chemistry at the metal interface [1]. It

causes corrosion termed as Microbiologically Influenced Corrosion (MIC) [2], particularly local

corrosion such as pitting corrosion, crevice corrosion and de-alloying corrosion [3].

It has been reported that besides Sulfate Reducing Bacteria (SRB) which are the most bacterial

group involved in Marine Microbiologically Influenced Corrosion (MMIC), sulphur-oxidising bacteria,

iron-oxidising/reducing bacteria, manganese-oxidising bacteria and bacteria secreting organic acids and

exopolymers are also associated with metal corrosion in marine environment using complicated

mechanisms [4].

Thus, this paper provides an overview of the literature that examines the relationships between

these bacterial groups and electrochemical reactions occurring at the metal-environment interface and

implicated in the MMIC processes. Furthermore, as the seawater is considered to be one of the most

complex chemical system, the physico-chemical parameters of seawater ( temperature, dissolved oxygen

content, salinity, water chemistry, pH, time of wetness, high atmospheric contaminants, pollution and

fluid velocity) that are involved in MIMC mechanisms and influence corrosion severity in marine

environment [5] will also be touched upon.

The aim of this study was to investigate the effect of the growth rate and heat treatment on the

corrosion behavior of directionally solidified Al–13wt.%Mg2Si pseudo eutectic alloy. The composition of

Al–13wt.%Mg2Si pseudo eutectic alloy was chosen to be Al–8.25wt.%Mg–4.756wt.%Si to the Mg2Si

solid phase within an aluminum matrix (-Al) from its melts. Al–13wt.%Mg2Si pseudo eutectic alloy was

directionally solidified at a constant temperature gradient with different growth rates, 8.3 and 175.0 µm s-

1 by using a Bridgman-type furnace.

The Samples of Al–13wt.%Mg2Si pseudo eutectic alloy were treated at 540oC for 2 h for heat

treatment, followed by quenching in cold water and subsequently aged at 180oC for 4 h (T6 heat

treatment).

The directionally solidified and heat treated samples were removed from the graphite crucible and

typically cut into lengths of 80 mm. After moulded each sample, it was sanded and polished. The polished

samples were etched with 2ml of hydrofluoric acid, 3ml of hydrochloric acid and 5ml of nitric acid in 190

ml of distilled water for 25-30 s in order to reveal their microstructures. The microstructure of the

samples was photographed by a ZEISS Gemini 500 model field emission scanning electron microscopy

(FE-SEM).

The corrosion studies of the samples were investigated by Tafel polarization curves and

electrochemical impedance spectroscopy (EIS) techniques. The all measurements were carried out using

an electrochemical workstation system (Gamry, Interface 1000), and a conventional three-electrode cell

in 3.5% NaCl solution at 25 °C.

Key Word: Aluminum Alloy; Heat Treatment; Corrosion Test; Electrochemical impedance spectroscopy; Tafel

Corrosion processes are responsible for considerable costs. Among the various techniques to stop or

prevent destruction or degradation of metal surface and alloys, the corrosion inhibitor is one of the best

known options of corrosion protection and the most useful in the industry [1,2].The environmental

toxicity of organic and inorganic corrosion inhibitors have encouraged researchers for green corrosion

inhibitors with the economic benefits as they are low cost, biodegradable, without heavy metals [2, 3]. In

addition, they are ecofriendly, ecologically acceptable and renewable source [5]. The present work

proposes the study of the cuminaldehyde as a green inhibitor extracted from the essential oil of cumin

against the corrosion of steel in 1M HCl. This inhibitor has been investigated by using potentiodynamic

polarization and Electrochemical impedance spectroscopy (EIS) techniques with the intention of

determining the corrosion inhibition efficiency. The thermodynamic studies show that the adsorption of

inhibitor on steel was mixed adsorption and exothermic in nature. The adsorption process shows that the

inhibitor follows Langmuir isotherm. The morphological analysis of steel was checked before and after

adding inhibitor by Fourier transform infrared (FTIR) and the changes of contact angles were determined,

scanning electron microscopy (SEM) and the surface composition was analyzed using energy dispersive

X-ray (EDX). This study was completed with theoretical studies using DFT and QSAR..

Steel and aluminum alloys are the two most popular materials used in industries. Each material has

a defined and distinct set of characteristics that make it the right material for the right application.

However, cost and price are not the only characteristics that industrials take into consideration. In fact,

corrosion resistance is one of the most important properties. Therefore, a comparative study on the

corrosion behavior of mild steel and aluminum in hydrochloric acid will be presented in this work. In

order to minimize corrosion rate of those metals in HCL medium, plant extract, as ecofriendly way, is

used in this study to avoid toxicity of organic compounds.[1-2].

Moreover, corrosion inhibition effect of Lavandula marocanna extract was also investigated using

electrochemical measurements. LM Extract was added to the acidic medium in different concentrations

50,100,200,400 ppm.

The main electrochemical method that has been used is electrochemical impedance spectroscopy

method was investigated at 35°C using a potentiostat device controlled by a software. The high inhibition

efficiency is 89% for mild steel in 1M HCl using 400ppm of LM extract. For aluminum alloy used in this

study, the high inhibition efficiency reached 65%. Weight loss method was used to evaluate the

concentration effect and adsorption isotherm of this green inhibitor on the corrosion behavior of both

aluminum and mild steel metal. LM aqueous extract is used as green inhibitor for mild steel and

aluminum corrosion

SUSCEPTIBILITY OF ALUMINUM ALLOYS PRODUCED BY DIFFERENT

CASTING TECHNIQUES TO LOCALIZED CORROSION STUDIED BY

ELECTROCHEMICAL NOISE MEASUREMENTS

Levent ORGAN*, Öykü G. ZALOĞLU, Berk H. GAZIOĞLU

Yeditepe University, Chemical Engineering Department, ISTANBUL / TURKEY

Aluminum alloy sheets, AA1050 and AA5005, produced by direct-chill casting (DCC) and hot-

rolling process and the same alloy sheets produced by the twin-roll casting (TRC) are compared for their

susceptibility to localized corrosion by means of electrochemical noise measurements. As a result of

faster solidification, absence of homogenization and significantly less hot working, alloy sheets produced

by the TRC route are known to have structures different than their DCC counterparts [1], [2]. DCC alloys

usually have a more uniform microstructure [3], while the intermetallic particles in the TRC alloys are

generally smaller than those in DCC alloys [2]. Since localized corrosion in aluminum alloys are

generally associated with intermetallic particles [4], the present study was conducted to determine any

differences in susceptibility to localized corrosion of AA1050 and AA5005 produced by the TRC and

DCC.

To determine any differences between the localized corrosion susceptibility of the DCC and TRC

alloys of the same type, electrochemical noise experiments were conducted in naturally aerated 0.1 M and

0.01 M NaCl solutions. Instrumental noise of the measurement set-up was checked as described in the

literature [5]. Electrochemical noise measurements were conducted by the ZRA technique. The galvanic

current between two nominally-identical electrodes were measured. The measurements were done 10

minutes after the immersion for 3 hours to see the differences in the initial corrosion behavior. ZRA

measurements were also performed after 24 hours of immersion of all alloys. The electrochemical noise

data were analyzed with various frequency and time-series analysis methods. The electrochemical noise

measurements revealed differences between TRC and DCC alloys at different exposure times. Key Words: Aluminum Alloy, Localized Corrosion, Electrochemical Noise, Twin-roll Casting, DC casting

SICAK DALDIRMA YÖNTEMİ İLE ALÜMİNYUM KAPLANMIŞ YAPI

ÇELİKLERİNİN KOROZYON ÖZELLİKLERİNİN İNCELENMESİ

Furkan KALAN1, Fadime AKPINAR1, T. Çağrı ŞENOCAK1, K. Vefa EZİRMİK*1 1Atatürk Üniversitesi, Metalurji ve Malzeme Mühendisliği Bölümü, Yakutiye / ERZURUM / TÜRKİYE

Günümüzde korozyon, çelik malzemelerde oluşan en önemli bozunma proseslerinin başında gelmektedir.

Fakat korozyonun çelik üzerinde bırakacağı etkiler ve yol açacağı maddi zararlar önceden alınacak olan

önlemlerle minimuma indirgenebilir. Çelik konstrüksiyonlarda meydana gelen korozyonu ortadan

kaldırmak amacıyla bir takım kaplama prosesleri uygulanmaktadır [1]. Bu prosesler arasında çevresel

koruma, ekonomiklik ve seri üretim için uygunluk faktörleri ve üstün korozyon direnci dikkate

alındığında, sıcak daldırma ile alüminyum kaplama işlemi oldukça pratik ve elverişli bir yöntem olarak

dikkatleri üzerine çekmektedir [2].

Bu çalışmada, düşük korozyon direncine sahip olan genel yapı çeliklerinin yüzeylerine sıcak daldırma

metodu kullanılarak 1XXX, 2XXX ve 5XXX serisi alüminyumla kaplanmıştır. Yüzeyleri hazırlanmış

olan yapı çelikleri, Al/Al alaşımı banyosuna 1,3 ve 5 dakika sürelerde daldırılarak kaplama işlemi

gerçekleştirilmiştir. Kaplama sonucunda çelik yüzeyi ile kaplama arasında intermetalik yapıların oluştuğu

gözlemlenmiştir. Özellikle 1XXX serisi alüminyum kaplamalarda intermetalik yapının kalınlığını ve buna

bağlı olarak kırılganlığını azaltmak amacıyla sıvı alüminyum banyosu içerisine değişen oranlarda metalik

silisyum (Si) ilavesi yapılmıştır. Alüminyumun ve içerisinde ihtiva ettiği alaşım elementlerinin çelik

yüzeyinde oluşturduğu difüzyon tabakasının morfolojisi optik ve taramalı elektron mikroskobu (SEM) ve

X-ışını kırınımı (XRD) cihazları ile incelenmiştir. Alüminyum kaplanmış ve kaplanmamış çelik

numuneler tuzlu su ortamında korozyon testine tabi tutulmuştur. Test sonucunda numunelerin kütle

değişimleri ve metalografik incelemeleri yapılmıştır. Alüminyum kaplanmış çelik numunelerdeki ağırlık

değişimleri ölçülmüş ve önemli bir değişiklik olmadığı belirlenmiştir. Alüminyum kaplanmış çelik

numunelerin tuzlu su ortamında kaplama yapılmamış çeliklere göre korozyona karşı daha yüksek direnç

gösterdiği tespit edilmiştir.

Anahtar Kelimeler: Alüminyum, yapı çeliği, sıcak daldırma, korozyon dayanımı.

In industries numbers of corrosion problems mainly arise due to the use of hydrochloric acid (HCl)

for pickling, rescaling and cleaning processes of mild steel surface[1]. No absolute method have been

designed up till now for complete removal of corrosion, but we can take protective measures in order to

control the effect of corrosion. Thus among various methods that have been used for slowing and

monitoring acid corrosion the use of organic inhibitor is the most experienced one [2]. Among these

organic inhibitors, the literature shows that Schiff bases are found to be an as active corrosive inhibitor

for several metals and alloys in acidic media[3]. In the present work, a new sulfur containing Schiff base

(5-(4-(diethylamino)benzylidene)amino)-1,3,4-thiadiazole-2-thiol) (5-DAT) was synthesized. Corrosion

inhibition of S5-DBATT was studied against mild steel in 1.0 M HCl solution using sophisticated

Analytical methods like potentiodynamic polarization, electrochemical impedance spectroscopy, and

linear polarization resistance. Electrochemical impedance spectroscopy results show highest inhibition

efficiency (η%) of 91.8% for 3mM 5-DAT.

Beton normal halde betonarme demirleri için hem kimyasal, hem de fiziksel olarak iyi bir koruyucu

ortam oluşturur. Çimento + su reaksiyonu sonucu kalsiyum hidroksit oluşur ve beton oldukça yüksek bir

alkali özellik kazanır. Beton pH derecesinin yüksek oluşu betonarme demiri yüzeylerinde pasif bir oksit

filmi oluşmasına neden olur. Diğer taraftan betonun geçirgenliğinin düşük oluşu, korozyona neden olan

bileşenlerin beton içine girmesini ve betonarme demirleri yüzeyine kadar ulaşmasını güçleştirir. Bir

elektrolit olarak betonun iyonik iletkenliği çok düşüktür. İletkenliğin düşük oluşu betonarme demirleri

yüzeyinde korozyon hücrelerinin gelişmesini güçleştirici bir etki gösterir. Betonarme demirlerinin

korozyonuna genellikle deniz suyu veya deniz atmosferi etkisinde kalan beton yapılarda, klorür tuzlarının

kullanıldığı bazı kimyasal fabrikalarda, karayolu köprüleri ve viyadüklerde rastlanmaktadır [1].

Bu çalışmada, sepiyolit kili katkısının çimento harç özellikleri ve betonarme çeliği korozyonu

üzerine etkileri incelendi. Eskişehir ili Sivrihisar ilçesinde yüzeylenen tabakalardan alınan sepiyolit

kilinin fiziksel ve kimyasal özellikleri araştırıldı. Sepiyolit kili katkısı, CEM I 42,5 R Portland

çimentosuyla ağırlıkça %0, %2.5, %5, %7.5, %10, %12.5 ve %15 oranlarında yer değiştirilmek üzere

kullanılarak silindirik Ø50*100 ebatlarında harç numuneleri üretildi ve üretilen harç numuneleri %3.5

NaCl konsantrasyonuyla hazırlanan suda olgunlaştırıldı.

Harç numuneleri içine gömülü donatı çeliğinin elektrokimyasal korozyon parametrelerinin

belirlenmesinde üç elektrotlu ölçüm yöntemi kullanılmıştır ve voltametrik ölçümler CHI604e programı

ile bilgisayar kontrollü CH Instruments (600E) model potansiyostat cihazı kullanılarak yapılmıştır. Bu

yönteme göre çalışma elektrotu olarak korozyonu ölçülecek betonarme çeliği, karşıt elektrot olarak platin

ve karşılaştırma elektrodu olarak da doygun kalomel elektrot (SCE) kullanıldı. Donatı gömülü harç

numunelere önce korozif ortamdaki bekleme sürelerine bağlı kronoamperometrik ölçümler, polarizasyon

direnci (Rp) gibi tahribatsız elektrokimyasal testler uygulanmıştır.

Bu deneyler sonucunda elde edilen bulgulara ait çeşitli elektrokimyasal parametreler grafik ve

çizelgeler halinde düzenlenerek malzeme korozyon özellikleri karşılaştırılmış ve korozyon mekanizmaları

belirlenmiştir.

145 gün korozif ortamda kalan numunelerden çeşitli günlerde ölçümler alınmış ve bu günlere ait

polarizasyon dirençleri ve korozyon akımları birlikte değerlendirildiğinde %5 sepiyolit ikamesiyle

oluşturulan çimento harç numunesinin korozyona en dirençli koşulları sağladığı görülmüştür. Anahtar Kelimeler: Çimento, Korozyon, Sepiyolit.

NiPd ELEKTROKATALİZÖRLERİN ELEKTROLİZ KOŞULLARINDAKİ

KOROZYON DAVRANIŞLARI

Ramazan SOLMAZ*

Bingöl Üniversitesi, Sağlık Bilimleri Fakültesi, İş Sağlığı ve Güvenliği Bölümü, 12000, BİNGÖL / TÜRKİYE

Dünya genelinde kullanılan enerji kaynaklarının büyük çoğunluğunu fosil yakıtlar oluşturmaktadır.

Ancak, rezervlerinin giderek tükenmesi, fiyatlarının sürekli arması, insan ve çevreye olumsuz etkileri gibi

nedenlerle çalışmalar alternatif enerji kaynakları üzerinde yoğunlaşmıştır. Bunların içerisinde hidrojen

gazı geleceğin enerji taşıyıcısı olarak kabul edilen en önemli yakıtlardan biridir. Birçok üretim yöntemi

olmakla birlikte çok miktarda ve en saf hidrojen gazı suyun elektrolizi ile yapılabilmektedir. Hidrojen

üretim reaksiyonunu en iyi katalizleyen metaller Pt, Pd, Ir gibi Pt-grubu metallerdir [1, 2]. Ancak bu

metallerin pahalı olması maliyeti arttırmakta ve pratikte kullanımlarını sınırlamaktadır. Bu

dezavantajların giderilmesi için diğer ucuz geçiş metalleri ile alaşımlarının oluşturularak kullanılmaları

yaygın yöntemlerden bir tanesidir. Bu tür elektrokatalizörlerin geniş yüzey alanına sahip altlıklara

tutturularak kullanılması bir diğer önemli yöntemdir. Daha önceki çalışmalarımızda oldukça hafif, ucuz

ve geniş yüzey alanına sahip karbon keçenin (C) katot yapımında kullanılabileceği önerilmiştir [3].

Bununla birlikte, enerji ve elektroliz sistemlerinde korozyon ile ilgili yeterli çalışmaların yapılmaması son

derece büyük bir eksikliktir. Çünkü oldukça pahalı metallerin korozyona uğramaları verimlerini

düşürmekte ve ömürlerini azaltmaktadır.

Bu çalışmada enerji sistemlerinde elektrot malzemesi olarak kullanılabilecek önceden Ni modifiye

edilmiş C/Ni üzerine çok az miktarda ikili NiPd çöktürülmüş C/Ni-NiPd elektrokatalizörlerin elektroliz

sistemindeki (1 M KOH çözeltisi) korozyon davranışı incelenmiştir. Elektrokatalizörler taramalı elektron

mikroskopu, enerji dağılımlı X ışını spektrospkopisi ve X Işını kırınımı ile karakterize edilmiştir. Bu

amaçla, çok sayıda elektrokimyasal teknik kullanılmıştır. Elde edilen bulgular, elektrokatalizörlerin

özellikle kısa süreli de olsa elektrik kesintilerinin elektroliz sisteminde korozyon dayanımlarının

değiştiğini ve bunun da elektrotun performansına etki edeceğini göstermiştir. Anahtar Kelimeler: Enerji sistemleri, korozyon, elektrokatalizörler.

Kendi kendine biriken tek tabakalı filmler (SAM) oldukça yoğun, sıkı, iyi düzenlenmiş, ultra ince

organik filmlerdir. Metal yüzeyinde film oluşturma teknikleri arasında sahip oldukları özellikler dolayısı

ile son derece önemli avantajları vardır. Filmlerin çok yaygın kullanılma potansiyelleri olup en

yaygınlarından biri korozyondan korunmadır. Ancak, bu amaçla kullanılan maddelerin çoğu çok pahalı

veya toksittir. İnsan ve çevreye olumsuz etkileri olmayan, sağlıklı yeni filmlerin bu amaçla geliştirilmesi

son derece önemlidir. Rodanin ve türevleri oldukça sağlıklı bileşikler olup antibakteriyel, antiviral,

antimikrobiyal özellikler sahip olup çok sayıda biyokimyasal uygulamaları mevcuttur. Metilrodanin

(MRh) SAM filminin bakırın korozyonuna inhibisyon etkisinin iyi olduğu, ancak film kusurları olduğu

rapor edilmiştir. Filmlerin kalitesinin arttırılması için ilave yöntemler gerekmektedir.

Bu çalışmada etanol içerisinde bakır yüzeyinde MRh-SAM filmleri hazırlanmış ve yüzeyleri metal

çöktürülerek daha da iyileştirilmiştir. Metal modifiye işlemleri elektrokimyasal olarak özel hazırlanmış

kaplama banyolarında elektrokimyasal olarak gerçekleştirilmiştir. Hazırlanan filmler çok sayıda

spektroskopik, mikroskobik ve elektrokimyasal teknik ile karakterize edilmiştir. Filmlerin bakırın

korozyonuna inhibisyon etkileri %3,5 NaCl çözeltisinde elektrokimyasal impedans spektroskopisi, açık

devre potansiyelinin zamanla değişimi, akım-potansiyel eğrileri ve lineer polarizasyon direnci teknikler

ile incelenmiştir. Elektrokimyasal kararlılıkları dönüşümlü voltametri ve kronoamperometri ile

incelenmiştir.

Anahtar Kelimeler: Kendi kendine biriken tek tabakalı filmler, bakır, korozyon, metal çöktürme.

CORROSION BEHAVIOR OF SNO2-COATED MILD STEEL IN

HYDROCHLORIC ACID SOLUTION

Sevgi ATEŞ*1, Evrim BARAN2, Birgül YAZICI1 1Çukurova University, Chemistry Department, Balcalı / ADANA / TURKEY

The mild steel is an attractive structural material due to its low cost, recyclability, high thermal

conductivity and excellent mechanical strength. But, the corrosion resistance of this material is the most

significant problem [1]. One of the most common methods for extending the life of this material is the

application of protective coatings. SnO2 is one of the most promising metal oxide applied in anti-

corrosion coatings. In this study, SnO2 was synthesized by the sol-gel technique and coated on mild steel

at different coating time (0,15,35 and 45 minutes) by dip-coating method , in order to protect mild steel

against corrosion. The corrosion performances of the uncoated mild steel (Yç) and SnO2 coated mild steel

(Yç-SnO2) were investigated in 0.5 M HCl solution at periodic intervals (2-96 h) by electrochemical

impedance spectroscopy (EIS) and potentiodynamic measurements. The structure and morphology of

electrodes were characterized by field emission scanning electron microscope (FE-SEM), energy-

dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and the contact angle measurements. The

FE-SEM results showed that SnO2 protects the surface against corrosion by forming a protective film on

the surface. The data obtained from the EIS measurements showed that the corrosion resistance of SnO2

coated mild steel increased over time. All parameters reveal that the SnO2 effectively protected on mild

steel against corrosion and reduced its corrosion rate in 0.5 M HCl solution.

Figure 1. The EIS results and SEM images of Yç (a) and Yç-SnO2 (b) obtained in 0.5 M HCl solution after 96 h immersion

time.

Gelişen ürün ağı ile birlikte kompozit malzemelerle ilgilenen araştırmacılar hasarlarının çoğunluğu

bağlantı yani eklem bölgelerinden kaynaklı olduğu gözlemlemiştir. Sonuç olarak da çalışma güvenliği

araştırmacıların ilgisini çeken konulardan olmuştur. Geleneksel yöntemlerden uzaklaşıp uygulama

kolaylığı sunan, düşük maliyetli ve hafif olmalarından kaynaklı yapıştırma bağlantıları kullanımı

yaygınlaşmıştır. Epoksi yapıştırıcıların popülerliği mekanik özelliklerinin gelişmesine yol açarak; nano-

kauçuk parçacıkları, karbon nanotüpler, grafen ve gümüş nanoteller, nano-kil, alümina ve silika

nanopartiküller gibi nanoparçacık takviyelerinin uygulamalarının yapılmasını sağlanmıştır.

Çalışma, saf su ortamında şartlandırılmış yapıştırma bağlantılarında N6.6 ile modifiye edilmiş

epoksi yapıştırıcının tek taraflı bindirme bağlantıları hazırlanmış ve eksenel darbe testinin numuneler

üzerindeki etkileri incelenmiştir. Tek taraflı bindirme yoluyla yapıştırılmış bağlantıların eksenel darbe

sonrası etkileşimlerin değerlendirilmesi, mevcut deneysel çalışmanın temel amacı olmuştur. Yapıştırma

işlemlerinin uygulandığı malzemeler; yapıştırılan olarak seçilen Al levha, karşı tarafında karbon elyaf

takviyeli kompozit levha seçilmiştir. Farklı sürelerde saf suda korozif şartlandırılmış numunelere çeşitli

enerji yüklerine sahip eksenel darbeler uygulanmıştır. Böylece numunelerin eksenel darbe sonrası ani

yüklemeye karşı taşıdığı yük incelenmiştir. Modifiye için gerekli naylon 6,6 nano elyaflar elektro-spin

metodu ile üretilmiş ve tek taraflı bindirme bağlantılarının üretiminde kullanılmıştır. Bağlantı yapılmış

numunelerin üretimi tamamlandıktan sonra 0, 1, 7, 14 ve 21 gün süreler ile saf suda şartlandırma

yapılmıştır ve etkileri farklı yükleme koşulları altında eksenel darbe testi yapılarak incelenmiştir. Naylon

6,6 takviyeli yapıştırıcının mekanik özelliklerinin gözlemlenmesi için tek taraflı bindirme bağlantısı

ASTM D1002-10 standardizasyonunda hazırlanmıştır. Epoksi yapıştırıcının özelliklerinin

güçlendirilmesinde kullanılan naylon 6,6 nano elyafların nitelik özellikleri taramalı elektron mikroskopu

(SEM) yardımı ile incelenmiştir.

YÜKSEK KARBONLU ÇELİK TELİN SOĞUK DEFORMASYONU SIRASINDA

ÇİNKO FOSFAT KAPLAMA İŞLEMİNE ALTERNATİF YENİ NESİL

KAPLAMA YÖNTEMİ

Elvan ARAZ*1, Erkan KARAYİĞİT1 1Güney Çelik Hasır ve Demir Mam. San.Tic. A.Ş / ADANA / TÜRKİYE

Metal yüzeyleri kaplama işlemine tabi tutulmadan önce ön hazırlık basamaklarından geçirilir. Bu

basamaklardan bir tanesi de çinko fosfat kaplamadır. Mevcut proses; basamak sayısının fazla olması,

oluşan çamurlaşmanın bertarafının zor ve yüksek maliyet içermesi, çevreci bir yaklaşım olmaması gibi

dezavantajlara sahiptir. Yapılan çalışma ile çinko fosfat kaplamaya alternatif kaplama olarak

planladığımız bu çalışmada çevreye duyarlı olması açısından stearatlar ile çalışılarak tel üzerindeki

etkileri incelenmiştir. Daldırma yöntemi uygulanarak, farklı pH, süre, sıcaklık ve derişimler de yapılan

çalışmalar sonucu elde edilen kaplamanın çinko fosfat kaplama ile kıyaslaması yapılmıştır. Alternatif

kaplama ile kaplama süresi azaltılabilmektedir. Kaplama prosesi; yüzey temizleme ile birlikte 7

kademede sonlandırılırken, alternatif kaplama yöntemi ile 3 kademede tamamlanabilmektedir. Ayrıca

alternatif kaplama ile korozyon direncinin arttığı, maliyetin %70-80 arası azaldığı görülmüştür. Böylece

alternatif kaplamanın çinko fosfat kaplamaya üstünlük sağlayan bir kaplama türü olduğu anlaşılmıştır.

Anahtar Kelimeler: korozyon, kaplama, çelik, çinko fosfat,

The corrosion behaviour of copper in 3.5% NaCl solution (pH=3.5) with the absence and presence

of phenol red has been investigated by electrochemical techniques such as potentiodynamic polarization

and electrochemical impedance spectroscopy (EIS). The optimum concentration of the studied inhibitors

showing highest inhibition efficiency was also evaluated at constant temperature (298 K). The inhibition

efficiency was found to increase with increase in concentration of phenol red. Thermodynamic parameter

for the adsorption process were determined. Scanning electron microscopy (SEM) observations of the

mild steel surface confirmed the existence of such an adsorbed film.

The corrosion behavior of reinforcing steel was investigated in chloride solutions, in the presence of

0.5% polycarboxylate based superplasticizer of cement weight. Electrochemical impedance spectroscopy

(EIS) and potentiodynamic polarization measurements were used for this purpose. The pH of the solution

was adjusted to 8.0 at constant temperature (298 °K). The polycarboxylate based superplasticizer could be

inhibited anodic dissolution of reinforcing steel in aggressive chloride media. Due to the chloride

penetration is reduced with polycarboxylate based super plasticizer. The inhibition effect of

polycarboxylate based superplasticizer was resulted from complex formations (between polycarboxylate

plasticizer and corrosion products).

PANI/NiO ve PANI/TiO2 KOMPOZİTLERİN ELEKTROKİMYASAL OLARAK

L304 ÇELİK YÜZEYİNE KAPLANMASI VE KOROZYON DAVRANIŞLARININ

İNCELENMESİ

İletken polimerler, çok yönlü ve kullanışlı karakteristik özelikleri içermesinden dolayı, geniş bir

uygulama potansiyeline sahiptir. Bu uygulama alanlarından biri de, metal korozyonunun önlenmesinde

organik kaplama malzemesi olarak kullanılmasıdır. Ancak iletken polimerlerin antikorozif kaplamaları

sırasındaki temel sorun, gözenekli yapıda su tutulmasına bağlı olarak dayanıklılığın azalmasıdır. Bu

amaçla, polimerik kaplamaların uzun süre dayanımını arttırmak için, yarı iletken karakterli (TiO2, ZnO,

Sb2O3 gibi) metal nano oksit katkı maddesi olarak kullanılmaktadır [1]. Bu amaçla çalışmamızda, 0,5 M

okzalik asit ve 0,2 M anilin içeren elektrolit çözeltisi içerisine farklı miktarlardaki (0,1 g ,0,3 g , 0,5 g)

NiO , TiO2 inorganik nano metal oksit içeren ve içermeyen ortamlarda dönüşümlü voltametri yöntemi ile

elektrokimyasal olarak L304 çelik elektrot yüzeyine polimerik kompozit (PANI, PANI/nano metal oksit)

kaplama yapılmıştır. Elektrokimyasal polimerizasyon yöntemiyle kaplanmış olan L304 Çeliğin klorür

içeren çözeltilerdeki korozyona karşı dayanıklılığı, Tafel polarizasyon ve empedans spektroskopi

yöntemleri kullanılarak araştırılmıştır. Metal yüzeyine kaplanan polimerik kompozitlerin yapı

karakterizasyonları Taramalı elektron mikroskobu (SEM), Fourier dönüşümlü kızılötesi (FTIR) ile termal

davranışları ise Diferensiyel tarama kalorimetrisi DSC analizleriyle karakterize edilmiştir. PANI ve

PANI/nanometal oksit (NiO, TiO2) ile kaplanan çeliğin 2,0 M NaCl çözeltisindeki korozyon davranışı

Tafel polarizasyon ve empedans spektroskopisi ölçümleri ile belirlenmiştir. Kaplamanın zamana bağlı

etkisi, kaplanmış çelik plakaların 7 gün içerisinde 2,0 M NaCl çözeltisinde bekletilerek SEM

görüntüleriyle incelenmiştir. Çalışma sonunda, L304 Çeliğin korozyonunu önlemede, sade PANI’nin

nano metal oksit içeren PANI’ ye göre fazla etkili olmadığı belirlenmiştir. Polimerik nano metal oksit

kompozitlerinden de 0,5 gr nano metal oksit (NiO, TiO2) içeren polimerik kompozitin metal yüzeyi

üzerinde diğerlerine kıyasla daha etkili olduğu belirlenmiştir.

Anahtar Kelimeler: elektrokimyasal polimerizasyon, PANI/nanometal oksit, iletken polimer.

CORROSION BEHAVIOR OF PANI/EPOXY/NANO SnO2 POLYMERIC

NANOCOMPOSITE COATED STAINLESS STEEL IN 3.5 % NaCl

Sibel ZOR, Nargiz ILMIEVA*

Kocaeli University Science-Art Faculty Chemistry Department, Kocaeli/TURKEY

Epoxy resin materials have been used as a matrix of anticorrosive coatings of polymeric nanocomposites

obtained by chemical polymerization due to outstanding processability, good electrical insulating properties of the

final material even at high temperatures [1], strong adhesion, high mechanical strength and good thermal properties

[2], excellent chemical resistance, better design flexibility and ease of application [3].

The present paper reports an approach to develop anticorrosion performance of PANI and

PANI/Epoxy/metal oxide polymeric nanocomposites on the surface of stainless steel L304. For this purpose, at

first, polyaniline nanocomposites containing metal oxide nanoparticles such as SnO2 with different ratios (0.1 g,

0.25 g, 0.5 g, and 1.0 g) were successfully synthesized by in-situ polymerization for improving the corrosion

efficiency of polyaniline. The synthesized polymeric nanocomposites have been characterized by Fourier transform

infrared (FTIR) spectroscopy, X-ray diffraction pattern (XRD), scanning electron microscopy (SEM), thermal

gravimetric analysis (TGA) and differential scanning calorimetry (DSC) analysis techniques. At the same time, to

enhance the mechanical and barrier properties of PANI matrix, polyaniline nanocomposites in the presence of

metal oxide nanoparticles were mixed with epoxy resin such as polyvinyl butyral (PVB) through a solution mixing

method and applied as additives in the polyaniline matrix. PANI/epoxy/metal oxide polymeric nanocomposites

were prepared as a thin layer coating and applied on polished AISI 304 stainless steel substrates and its corrosion

protection efficiency was investigated by potentiodynamic polarization and electrochemical impedance

spectroscopy (EIS) in 3.5 wt% NaCl as aggressive media. The surface morphology and the structure of the film

were evaluated by scanning electron microscopy (SEM). Finally, the obtained results revealed that

PANI/epoxy/SnO2 metal oxide nanocomposite coatings provided a significant protection against corrosive

environment.

TÜRKİYE

Alüminyum ve alaşımları, en yaygın olarak kullanılan demir dışı metal gurubudur. Yaygın

kullanımındaki üstünlüğünü onlarca yıldır devam ettirmesinin nedeni sahip olduğu hafiflik, uygun

koşullarda yapılan ısıl işlem ile elde edilen yüksek mukavemet ve yüksek korozyon direnci gibi

özellikleridir. Yüzey özelliklerinde yapılan iyileştirmeler, alüminyum ve alaşımlarının mevcut

avantajlarına yeni avantajlar ilave etmektedir.

Bu çalışmada, bor nitrür takviyeli akımsız nikel kompozit kaplamalar, anodize 1050 Al numunesine

uygulanmıştır. Al numuneler, önce sülfürik asit (H2SO4) çözeltisinde 5 dk süreyle anodize edilmiş, daha

sonra nikel florür çözeltisi kullanılarak aktifleştirilmiştir. Aktifleştirilmiş anodize yüzeye sahip olan

numuneler, standart akımsız nikel-fosfor (Ni-P) banyosunda (pH: 4.4-4.8), 85°C sıcaklıkta, farklı

miktarlarda (1, 5 ve 10 g/l) 0.5 µm boyutlu hekzagonal bor nitrür (h-BN) ilave edilerek kaplanmıştır.

Parçacık yüzeylerini aktifleştirmek ve toplanmalarını önlemek için kompozit kaplama çözeltisine yüzey

aktifleştirici madde olarak sodyum dodesil sülfat (SDS) ilave edilmiştir. Yapılan inceleme ve

hesaplamaların sonucunda kaplama içerisine giren hacimce h-BN miktarları, 1 g/l h-BN ilave edilen

numune için %0.94, 5 g/l numune için %4.34 ve 10 g/l numune için ise %7.56 bulunmuştur.

Kompozit kaplamanın yüzey morfolojisinin, klasik akımsız nikel kaplama yüzey morfolojisi olan

nodüler karnabahar yapısında olduğu yapılan mikroskobik incelemelerle tespit edilmiştir. Kompozit

kaplamalara 400°C’de kontrollü atmosferde (%100 Ar) 1 sa süreyle ısıl işlem yapılmıştır. XRD (X Işını

Kırınım Ölçer) analizi, amorf yapıdaki nikel matrisin ısıl işlem ile kristalin yapıya dönüştüğünü

göstermiştir. Isıl işlem ile ayrıca sertlik değerleri artmış ve en yüksek sertlik değerine 10 g/l ilaveli

numunede (1015 HV0,05) ulaşılmıştır.

Isıl işlemsiz ve işlemli akımsız nikel kompozit kaplamaların korozyon deneyleri %3.5 sodyum

AN ELECTROCHEMICAL STUDY EXAMINING THE EFFECT OF A NEWLY

SYNTHESIZED AROMATIC TYPE OF A SCHIFF BASE ON THE BEHAVIOUR

OF THE TEMPERATURE OF MILD STEEL IN HCl SOLUTION

Demet ÖZKIR*1 1Nigde Ömer Halisdemir University, Faculty of Arts & Sciences, Department of Chemistry, NIĞDE / TURKEY

Corrosion is one of the most important and up-to-date issues in both chemistry and engineering that

need to be carefully considered because of direct and indirect damages to the environment. For this

reason, almost half of the mild steel production in the industry is degraded due to corrosion and leads to

wasting. [1]. Recently, substitutional Schiff bases containing aromatic rings and heteroatoms have been

generally used to prevent metal corrosion [2,3]. In this study, the inhibitory effect of new aromatic type

Schiff base (DFMF) synthesized from the condensation reaction of 2,5-dichloroaniline and 2-

hydroxybenzaldehyde to mild steel corrosion in 1.0 M HCl solution was evaluated at 298 K and 328 K

temperatures using the potentiodynamic polarization method. This measurement indicate that DFMF

behaves as a cathodic controlled mixed-type inhibitor in acidic medium and prevents the corrosion of

mild steel even at higher temperature. Different isotherms have been tried to understand the adsorption of

DFMF molecules on the metal surface, and the most compatible of these adsorption isotherms is the

Langmuir isotherm. Temperature-dependent adsorption parameters such as adsorption equilibrium

constant (Kads), adsorption free energy (Gads) and activation energy (Ea) for the two temperatures were

calculated. As a result, the adsorption has come to be that it is spontaneous and strong on the metal

surface. The 3D surface images of the electrodes after 120 h immersion times in 1.0 M HCl were studied

with atomic force microscope (AFM) to obtain more detailed information on how the DFMF protected

the metal surface and the surface roughness. Thus, the result that DFMF is a good inhibitor for mild steel

in acidic medium is supported. Key Words: Aromatic Schiff base, adsorption, Tafel extrapolation, AFM.

DISENTANGLING THE RELATIONSHIP BETWEEN INHIBITION EFFECT

AND STRUCTURE OF TWO DRUGS: A THEORETICAL STUDY

Gökhan GECE*1, Semra BİLGİÇ2 1Bursa Technical University, Chemistry Department, Yıldırım / BURSA / TURKEY

Although the compact oxide film on aluminum surface is generally stable in the solutions of pH

ranges of about 4.5 to 8.5, it is subject to dissolution particularly in strong acidic or alkaline solutions [1].

To date, a number of different drugs has been investigated in several corrosive media for aluminum

surfaces, and successful results were obtained [2]. In a very new experimental study by Nathiya et al. [3],

two expired drugs, i.e., moxifloxacin and betamethasone (Figure 1), which are widely used for the

systemic treatment of bacterial infections and inflammation respectively, were considered as effective

corrosion inhibitors for aluminum in sulfuric acid solution. However, very little is known about the

interaction of these compounds with the aluminum surface and a description of inhibition mechanism at

the atomic level.

(a)

(b)

Figure 12. Optimized structures of (a) moxifloxacin and (b) betamethasone

In respect to this, quantum chemical calculations have been used in this study for a better

understanding of the inhibition effects of these drugs on the corrosion of aluminum in acidic media. For

this purpose, the structures and the ground-state energies of two drugs under investigation have been

analyzed employing density functional theory (DFT) as implemented in the Gaussian09 program. The

exchange-correlation functional, M06-2X was selected due to its good performance on ionization

potentials and electron affinities; dispersion-like interactions are also well characterized by this

functional. In addition, the double-zeta basis set, DGDZVP, was applied in order to include an all-

electron description of the different atoms present in the studied compounds. The reported optimized

geometries, molecular properties such as highest occupied molecular orbital energy (EHOMO), the

lowest unoccupied molecular orbital energy (ELUMO) and HOMO–LUMO energy gap (ΔE) as well as

essential global reactivity parameters have also been used to understand the inhibition efficiency of

moxifloxacin and betamethasone. Key Words: corrosion inhibitor, betamethasone, moxifloxacin, DFT.

ETİLEN GLİKOLÜN KOROZYON İNHİBİTÖRÜ OLARAK %3.5 NaCl

ORTAMINDA AA7075 ALAŞIMI İÇİN KULLANILABİLME POTANSİYELİNİN

ARAŞTIRILMASI

Hüsnü GERENGİ1, Ertuğrul KAYA*1, Fatima Erman BAĞCI1 1Düzce Üniversitesi, Mühendislik Fakültesi, Korozyon Araştırma Laboratuvarı, DÜZCE / TÜRKİYE

Alüminyumun üstün korozyon direncinin doğada kendiliğinden oluşan oksit tabakasından

kaynaklandığı bilinmektedir [1]. Alüminyum ve alaşımları yüzeyinde bulunan bu oksit tabaka asidik,

alkali çözeltiler ve özellikle klorür içeren çözeltilere maruz kaldığında tahrip olarak metali korozyona

uğratmaktadır [2]. Saf alüminyum metali dış ortamlara karşı zayıflık gösterdiği için kullanımı sınırlıdır.

Alüminyum metalinin özelliklerini ve kullanım alanını arttırmak için alaşımlama yapılmaktadır [3]. Bir

alüminyum alaşımı olan AA7075 metali alaşım olarak Zn, Mg ve Cu içermektedir. Bu alaşımın en dikkat

çekici özelliği yüksek mukavemet, mükemmel süneklik, tokluk ve yüksek yorgunluk özelliğidir. Bu

yüzden havacılık, otomobil, uzay ve inşaat gibi sektörlerde oldukça yaygın olarak kullanılmaktadır [4].

Diğer metallere göre avantajları nedeniyle AA7075 alaşımları etilen glikol/su transferi bulunan güneş

enerjisi, termal kolektör sistemleri ve otomobil radyatörlerinde kullanılan hafif, yüksek ısı iletkenliği olan

bir malzemedir [5,6]. Etilen glikolün araba radyatörlerinde kaynama sıcaklığını düşürmek için soğutma

sıvısı olarak kullanıldığı bilinmektedir [7]. Yapılan bu çalışmada AA7075 alaşımının %3.5 NaCl

çözeltisine hacimsel olarak %10, %20, %30, %40 ve %50 oranında ilave edilen etilen glikol içerisindeki

korozyon mekanizması; Tafel Ekstrapolarizasyon (TP) ve Dinamik Elektrokimyasal Empedans

Spektroskopisi (DEIS) yöntemleri kullanılarak araştırılmıştır. Kullanılan elektrokimyasal yöntemlerden

elde edilen sonuçların birbirleriyle uyumlu olduğu ve % 3.5 NaCl çözeltisine ilave edilen etilen glikol

miktarındaki artışa bağlı olarak AA7075 alaşımının daha az korozyona uğradığı tespit edilmiştir. Metal

yüzeyinin incelenmesinde kullanılan SEM, EDAX ve AFM analizleri etilen glikolün metal yüzeyinde

tutunarak metali korozyona karşı koruduğunu göstermektedir.

Düşük karbon çeliği (St37), mekanik özelliklerinin iyi olması, kolay işlenebilirliği ve uygun

maliyetli olması nedeniyle cıvata, somun, makine parça imalatı, yapı ve inşaat sektöründe en çok

kullanılan metaldir. Hidroklorik ve sülfürik asit gibi mineral asitler, ısıtıcı ve kazanların temizliği, pas ve

istenmeyen maddelerin arındırılması işlemlerinde sıklıkla kullanılmaktadır [1]. Bu uygulamalar, korozyon

sürecinin kontrol edilmemesi durumunda metal korozyonuna ve arızaya neden olmaktadır. Malzemeleri

korozyona karşı korumak için ortama korozyon inhibitörlerinin katılmasıyla, metalin yüzey kimyasının

değişmesi sonucunda korozyon olayı yavaşlamakta ve kontrol altına alınmaktadır [2]. Ancak inhibitör

seçimi yapılırken inhibitör mekanizması ve etkin konsantrasyonların değerlendirmesi dikkate alınmalıdır.

İnhibitör olarak kromat, nitrat, nitrit ve fosfat esaslı inorganik ve genellikle yapılarında N, O, S, P ve /

SEMI-CROWN ETHER LINKED SYMMETRIC CATIONIC GEMINI

SURFACTANTS, SYNTHESIS AND THEIR CORROSION INHIBITION

EFFECTS ON CARBON STEEL IN 1 M HCL SOLUTION

Serkan ÖZTÜRK*, Ayhan YILDIRIM

Bursa Uludağ University, Department of Chemistry, Görükle – Nilüfer / BURSA / TURKEY

Gemini cationic surfactants are compounds which are composed of two hydrophilic head groups

and two hydrophobic tails linked by a rigid or flexible spacer at the head groups or closed to them. The

spacer group may be hydrophobic or hydrophilic [1]. Gemini surfactants have higher efficiency and

effectiveness than their corresponding monomer counterparts. Compared to their corresponding monomer

counterparts, gemini surfactants have much lower critical micelle concentration (cmc) values, much

higher tendency to adsorb at interfaces, closer packing of the hydrophobic groups and higher solubility in

water. These unique properties of gemini surfactants make them useful on the applications as emulsifiers

[2], dispersants [3], coating agents [4] and corrosion inhibitors [5].

In this study, two novel cationic gemini surfactants with hydrophilic oligo-oxyethylene spacer

group were synthesized and were characterized using spectroscobic methods (IR, and NMR). Critical

micelle concentrations and surface tension values were determined for the cationic gemini surfactants.

Corrosion inhibition tests were performed using the weight loss method at room temperature for 24 h on

carbon steel coupons in 1 M HCl. After result of the corrosion tests which were done using a low carbon

steel, fairly good inhibition efficiencies (over than 95 %) were obtained at different inhibitor

concentrations. To support the corrosion inhibition test results, surface images were obtained using

scanning electron microscopy (SEM) analysis.

Key Words: Synthesis, Cationic gemini surfactants, Corrosion, Carbon steel, HCl.

MOTT SCHOTTKY ANALYSIS AND CHRONOAMPEROMETRIC

MEASUREMENTS FOR THE PASSIVATION OF THE AISI 321 STAINLESS

STEEL

AISI 321 stainless steel is a very corrosion resistant, and widely used structural material in several

industrial applications. Although it’s satisfactory performance in most acidic industrial environments, the

stability of its protective passive film formed on the surface depends mainly on the concentration of the

chloride ions in the solution where the stainless steel is placed. The aim of the present investigation is to

study the corrosion behavior of the AISI 321 stainless steel in the sulfuric acid, for this purpose, the

processes of the passivation and the breakdown of the passive film were studied. The semiconductor

properties of the passive films have a crucial utility in understanding the resistance of the stainless steel

[1]. The mott schottky analysis were performed at different passive film formation potentials, the donor

acceptor densities were determined as well as the semiconductor character. It was found that the donor

density decreases with increasing the formation potential. Besides that, the effect of the applied potential

on the kinetic parameters of the growth and the pitting of the passive film was studied. The obtained

chronoamperograms reveal that the applied potential affects mainly the rate of growth as well as the

nucleation-growth of the pits. The analysis of the anodic polarization curves for different concentrations

of chloride ions in sulfuric acid have clearly shown that the critical potential of stainless steel pitting

decreases with increasing the amount of the chloride ions. The obtained findings were corroborated by

using the surface examination.

Key Words: Stainless steel, passivation, pitting, mott schottky, chronoamperometry.

INVESTIGATION of HOT CORROSION BEHAVIOUR

Rasiha Nefise MUTLU*, Mehmet Burak KOCA, Gülfeza KARDAŞ, Birgül YAZICI

ÇukurovaUniversity, Chemistry Department, Balcalı / ADANA / TURKEY

Nickel-based superalloys have experienced extensive development and found enormous attractions

over the past four decades. Especially, Inconel Ni–Cr–Fe superalloys, has been widely employed in many

applications such as turbine blades, combustion chambers and nuclear reactors owing to its excellent

creep properties, oxidation resistance and hot corrosion resistance[1].

In this study, by mixing micrometric metal powders at certain ratios, it is aimed to produce a new

material by powder metallurgy method.For this purpose, the powdery alloy was prepared to take into

account the compositions of cast alloys with high corrosion resistance and pressed to a high pressure to

obtain palletized metals.After this process, the obtained samples were subjected to the sintering process

under the N2(g) atmosphere.The samples were heated to 900◦C as a speed of 10 ◦C dk-1. It was kept at 900 ◦Cfor 45 minutes. It was then allowed to stand for 15 minutes in a 1000 ° C heated oven and then cooled

by the speed of 10 ◦C dk-1. Hot corrosion test with molten salt of the samples before and after sintering

process was carried out. For this experiment, the surface of the sample was covered with NaCl: Na2SO4

salts. Subsequently, molten salt was formed at 900 ◦C, and mass exchange with time at this temperature

was observed.Scanning electron microscope (SEM), X-Ray diffraction (XRD) and Energy dispersion

spectrometry (EDS)measurements of samples before and after hot corrosion were taken. Furthermore,the

contact angles of the samples were measured.

ZnNiMo ALAŞIM KAPLI BAKIR YÜZEYİNDE POLİPİROL FİLM SENTEZİ

İÇİN YANIT YÜZEY YÖNTEMİNİN UYGULAMASI

Hatay Mustafa Kemal Üniversitesi, Kimya Bölümü, Antakya, HATAY / TÜRKİYE

Metal ve alaşım kaplamalar korozyon koruması için etkili yöntemler olsa da, metallerin

oksitlenebilir yapısı nedeniyle uzun vade de farklı koruma teknikleri gereklidir. Son yıllarda yapılan

araştırmalar, yüzeyde elektrokimyasal yollarla kaplanabilen iletken polimerlerin, malzemeyi korozyondan

korumak için kullanılabileceğini göstermiştir [1-3]. Polipirolün (PPy) elektronik iletkenliğinin diğer

polimerlere oranla daha yüksek olması, elektrokimyasal ya da kimyasal yolla kolayca sentezlenebilir ve

elde edilen ürünün termal kararlılığının ayrıca mekanik özelliklerinin oldukça iyi olması Ppy’yi

literatürün oldukça aranan polimeri haline getirmiştir.[4]

Geçtiğimiz yıllarda literatürde Ppy'nin sentezi üzerine yapılan bir dizi çalışma ortaya çıkmıştır. Bu

çalışmaların ortak özelliği, dikkatli bir elektrokimyasal parametre seçimi talep etmeleridir. Bu nedenle,

araştırmacılar elektropolimerizasyon koşulları, uygulanan teknik, elektrolit çözeltisi ve pH değeri,

potansiyel aralık ve tarama hızı gibi parametreleri araştırmıştır [3-6]. Fakat bu çalışmaların çoğu klasik

yollarla gerçekleştirilmiştir. Bu çalışmalar tek parametre değişikliğinin aynı anda sonuca etkisini

incelemiştir. Fakat bu durum parametrelerin birbiriyle etkileşimini açıklamak için yetersizdir. Ancak,

Yanıt Yüzey Yöntemi (YYY), aynı anda birçok parametrenin sonuçlarındaki değişimi incelemek için

kullanılabilecek ve literatürdeki birçok disiplinde kullanılan matematiksel yöntemlerden biridir. [7-8]

Bu çalışmada, bakır elektrotun yüzeyi belli bir kalınlığa sahip çinko-nikel-molibden (ZnNiMo)

alaşımı ile kaplanmış ve sulu nötr ortamda molibdat iyonları varlığında Ppy filmi, yüzey üzerine

sentezlenmiştir. Sentez parametreleri Box-Behnken deney tasarımı ile modellenmiştir ve değişken sentez

parametrelerinin yüzey üzerindeki istatistiki etkilerinin incelenmesi ve yanıt yüzey grafikleri

oluşturulması amaçlanmıştır.

Anahtar Kelimeler: korozyon, cinko-nikel-molibdat, polipirol, yanıt yüzey yöntemi.

Paslanmaz çelikler (SS), mekanik mukavemet, korozyon direnci, biyouyumluluk, vb. nedeniyle

endüstrilerde ve günlük hayatta yaygın olarak kullanılmaktadır [1-4]. Yüzeydeki koruyucu pasif film

olarak Cr oksit ve / veya hidroksitler içerir [5,6]. Fakat paslanmaz çelikler klorür veya sülfat iyonu içeren

ortamlarda korozyona uğrayabilir [7]. Paslanmaz çeliklerde daha fazla koruyucu arayüz oluşturmak için

organik ve inorganik kaplamaların veya organik ve inorganik inhibitörlerin, kompozit materyal

kaplamanın, nano-kaplamanın ve plazma kaplamalarının veya iletken polimer kaplamaların kullanımı gibi

çeşitli stratejiler geliştirilmiştir. Bu bağlamda, polimerler, önemli ölçüde ilgi çekmeye devam ediyor.

Korozyona dayanıklı kaplamalar ve kapsamlı çalışma iletken polimerlerin kullanımı üzerinde

gerçekleştirilmiştir[8-10]. Paslanmaz çeliğin korozyondan korunumu için polianilin (PANİ) ve türevleri

ile ilgili kapsamlı çalışma yapılmıştır. Literatürde PANİ ve türevlerinin polimer filmlerin çeşitli

özelliklerini (kararlılık, iletkenlik, gözeneklilik) iyileştirdiği gözlenmiştir. Literatürde organik madde olan

C14H11NO3 (ANMA) henüz kullanılmamıştır. Polimer sentez ortamına eklenen organik bileşiğin

korozyon hızına etkisi bu çalışma ile araştırılmıştır.

Bu çalışmada poli(N-etil anilin) sentezi ortamına eklenen C14H11NO3 (ANMA)’nın korozyon

direncine etkisi araştırılmıştır. Bu amaçla, 2,5 mM konsantrasyonunda ANMA, 0,10 M (C4H9)4N(ClO4)

OF COATINGS

Mustafa Kaptanoglu*

Firat University, Engineering Faculty, Metallurgy and Materials Engineering, ELAZIĞ / TURKEY

In this study, effect of welding current change on wear and hardness properties of the coatings

obtained by using submerged arc welding (SAW) technique and submerged arc welding powders

containing %16 ferrochromium were investigated. In this direction; welding tests were performed using

current values in the range of 400 - 550 A. After the welding tests, the test specimens from welded

samples were subjected to macro hardness, micro hardness and wear tests. Macro hardness measurements

were made using the Rockwell measurement method and micro hardness measurements were made using

the Vickers measurement method. Wear tests were carried out on a wear loss basis using a method similar

to the pin-on-disk method. For all weld tests, experimental work was done using the same sizing and

samples with the same technical specifications. 12 x 10 x 10 specimens were cut from the test specimens,

and these specimens were used for both the hardness measurements and the wear tests. At the end of the

study, it was determined that the amount of chromium and carbon that was obtained by coating was

increased by increasing the current value used during welding tests and by constantly setting other

machine parameters. As the amounts of chromium and carbon passing through the coating increased,

there were an increase in macro hardness results and a partial fluctuation in micro hardness results were

determined. The highest hardness values were obtained the coating as 53 HRC using with 550 A, while

the lowest hardness values were obtained the coating as 37 HRC using with 400 A. In parallel with the

hardness results, the wear losses of the coating also decreased, in other words the abrasion resistances

also increased. In the worn surface analyzes, the wear surface lines turned from deep scratches and

continuous scratches to discontinuous scratches and thinner scratches were obtained.

Key Words: Welding current, wear, hardness, coating.

Firat University, Engineering Faculty, Metallurgy and Materials Engineering, ELAZIĞ / TURKEY

In this study, welding tests were performed on SAE 1020 steel surfaces using submerged arc

welding (SAW) powders containing 16 % ferrochromium. In welding tests, 4 welding tests were carried

out using currents in the range of 400 - 550 A and the effect of current change on coatings obtained were

investigated. S1 welding wire (electrode), is combined with the submerged arc welding flux containing

ferrochromium in the welding test. SAE 1020 steel test plate surfaces used in welding tests were cleaned

and free from all kind of corrosive and other impurities before the welding tests; welding powders were

preheated at 350 °C for 1 hour to remove possible moisture. In submerged arc welding machine, the

voltage and welding speed are constant and the polarity of the machine is set to positive (+). Coatings

obtained in this respect were investigated with visual, microstructural, chemical and XRD analysis. As a

results of visual analysis, removal characteristic of slag formed by the partial melting of the welding

powder decreased, the homogeneity of the weld seam did not change significantly and there were no

welding faults such as porosity in the weld metal were obtained. On the other hand; increasing of welding

current, the amounts of chromium and carbon passing through the coatings increased, so that the amount

of phases, such as carbide and martensite, in coating microstructures also increased were obtained. The

coating the highest ratio of martensite and carbide phases using 550 A welding current and the coating the

lowest ratio of martensite and carbide phases using 400 A welding current were obtained.

Key Words: Coating, welding current, microstructure.

Glucose and starch are non-toxic organic molecules whose characteristics are corrosion inhibitors

on different types of metallic materials [1-2]. Galvanized steel (GS) has widespread application in the

industry due to its excellent chemical, electrical and mechanical properties and especially corrosion

resistance. However, GS has been reported to be corroded by microorganisms [3]. Besides, there are

limited researches especially about fungal effects on corrosion. In our previous study, the corrosive effect

of Fusarium sp. fungus on GS was investigated by using Potato Dextrose Broth as medium over 3 days

[4]. However, to clarify the findings, it has been needed to determine that how glucose and starch in the

Potato Dextrose Broth affect the corrosion behavior of GS.

It was aimed to investigate the corrosion behavior of GS in glucose (2 %) and starch (0.4 %)

solutions by potentiodynamic polarization method. The experiments were carried out in acidic (pH 5.2)

glucose and starch solutions including NaCl (0.4 %) and the measurements were taken at certain time

intervals (0, 2, 4, 6, 8, 10, 24, 48, 72, 96, 120, 144, 168, 240, 336 h).

No significant changes were observed in Ecorr values of GS in both glucose and starch solutions

over exposure times. During the test, fluctuations in the corrosion rate of galvanized steel coupons were

observed. The maximum corrosion rate for glucose was found to be 3.72 mpy at 144 h and 3.36 mpy at

336 h for starch.

Key Words: Galvanized steel, Glucose, Starch, Potentiodynamic polarization test.

INHIBITOR EFFECT OF 1-BENZYL-3-METHYLIMIDAZOLIUM

TETRAFLUOROBORATE ON MILD STEEL

Gökmen SIĞIRCIK*

Çukurova University, Chemistry Department, Sarıçam / ADANA / TURKEY

For common inhibitors adsorption capability determines its corrosion efficiency and the adsorptive

behavior are directly explained by molecular structure and size. Generally, the organic molecules

including aromaticity, electronegative groups and heteroatoms reveal better adsorption interaction with

metal surface. Thus, corrosion rate could be decrease with the use of inhibitor for industrial application

such as pickling, descaling and cleaning purposes [1,2]. As a result, benzyl group containing imidazolium

with tetrafluoroborate could be good molecule as corrosion inhibitor.

The inhibition effect of 1-benzyl-3-methylimidazolium tetrafluoroborate has been studied on mild

steel corrosion in acidic environment. For this aim, electrochemical impedance spectroscopy and

potentiodynamic techniques were utilized for different inhibitor concentrations to obtain quantitative data

about the influence on corrosion. The results showed that applied corrosion inhibitor reveals good

inhibition efficiency for steel corrosion.

Key Words: Corrosion inhibitor, acid solution, mild steel.

INVESTIGATION of the OPERATING CONDITIONS on ELECTROLESS

NICKEL PLATING OVER ABS PLASTIC

Tuğba GÜRMEN ÖZÇELİK *1, Canan URAZ 1 1Ege University, Engineering Faculty, Chemical Engineering Department, Bornova / IZMIR / TURKEY

Electroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a

substrate without the use of electric current. It differs from electroplating which depends on an external

source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate. Electroless

nickel plating is a chemical process which reduces nickel ions in solution to nickel metal by chemical

reduction [1-3]. The aim of this study is to investigate the operating conditions of electroless nickel

plating over ABS plastic and determining the best plating conditions. Experimental study consists of four

parts as; preparation of materials, etching, coating and analysis. The effects of temperature and pH of the

plating bath, plating time and grinding paper size were investigated on nickel plating. Experiments were

carried out in the plating bath with 120, 240 and 320 grit size sandpapers, at 85-90-950C plating

temperatures, at 7-9-11 pH and 15-30-45 minutes of deposition times. The results of the experimental

studies analyzed by using Fischerscope X-Ray XDL-B System, X-ray Diffraction (XRD) and Scanning

Electron Microscopy (SEM). Due to the results of the experiments and analysis, the electroless nickel

plating on ABS plastic was a success.

Key Words: Electroless plating, ABS plastic, nickel plating.

ELECTROLESS METAL PLATING OVER ABS PLASTIC

Canan URAZ*1, Tuğba GÜRMEN ÖZÇELİK1 1Ege University, Engineering Faculty, Chemical Engineering Department, Bornova / İZMİR / TURKEY

Plating is used to decorate objects, for corrosion inhibition, to improve solder ability, to harden, to

improve wear ability, to reduce friction, to improve paint adhesion, to alter conductivity and for other

purposes [1]. Electroless plating is a fundamental step in the metal plating on the plastic [2-4]. In this

study, the electroless nickel and copper plating on Acrylonitrile butadiene styrene (ABS) were

investigated. The effects of the ionic liquids as catalyst, plating time and sanding paper size were

investigated on metal plating. Experiments were carried out with two different types of ionic liquids:

EMIC, 1-ethyl-3-methyl imidazolium chloride (C6H11N2Cl) and DCA, 1-ethyl 3-methylimidazolium

dicyanamide (C8H11N5) and with 120, 240, 320 and 500 grit sandpaper by applying sand attrition

process, and constant bath temperature as 60 ⁰C with 60,90,120,150 minutes of deposition times. Due to

the results, the copper plating on ABS plastic was a success. The surface morphology and amount of

deposit analysis were performed using the Fischerscope X-Ray XDL-B System, X-ray Diffraction (XRD)

and Scanning Electron Microscopy (SEM). Hence, it is determined that the maximum amount of deposit

Corrosion is one of the most important problems in the country's economy. Especially, a number

of methods prevent of aqueous medium corrosion are applied such as coating the metal to be protected

with a suitable metal, and using organic-inorganic inhibitors. In recent years, inhibitor studies have

become important in aqueous medium corrosion of metals [1,2]. In this study, benzamide and

thioacetamide containing amide (-NH2) groups as inhibitors were selected. Corrosion behaviors of

benzamide and thioacetamide were investigated at different concentration (10-5, 10-4, 10-3 and 10-2 M ) in

0.1 M NaCl solution by using potentiodynamic polarization method. Corrosion potentials (Ecorr) and

corrosion current densities (Icorr) were determined by Tafel polarization method. Surface coating

fractions with inhibitor efficiency (IE) were also calculated by using corrosion current density. Also,

adsorption free energy (∆𝐺𝑎𝑑𝑠0 ) and adsorption equilibrium constants (Kads) were determined from

Langmuir adsorption isotherm. Corrosion current densities of steel at 10-2 M inhibitor concentration in

0.1 M NaCl solution were determined at 303 K, 313 K, 323 K and 333 K, and the activation energies (Ea)

from the Arrhenius equation were calculated.

Corrosion inhibitive performance of benzamide and thioacetamide during the acidic corrosion of

steel surface was investigated using density functional theory DFT in gas and water phase. Quantum

chemical parameters such as the highest occupied molecular orbital energy (EHOMO),the lowest

unoccupied molecular orbital energy (ELUMO) , the energy band gap (∆EHOMO–LUMO), dipole moment (μD),

and other related parameters [ionization potential (𝐼), electron affinity (𝐴), electronegativity (𝜒),

chemical potential (𝜇𝑐), global chemical hardness (𝜂), softness (𝜎) and number of transferred electrons

(Δ𝑁)], were calculated for neutral and protonated forms. The theoretical results are in agreement with the

experimental data.

Key Words: amide derivatives, corrosion, inhibitor, quantum chemical calculations.

The flowers of Rheum Ribes is dried inner side, macerated with methyl alcohol and filtrated to

produce plant extracts. Experimental isolates were prepared by distillation method and solvent (methyl

alcohol) were removed. The prepared Rheum Ribes isolates of 1000 ppm in 1 M HCI were applied to

the mild steel in room conditions and resistance was measured to determine the effect of inhibition. For

this purpose, the inhibitory potential of Rheum Ribes was investigated as an inhibitor of mild steel in 1 M

HCI using electrochemical impedance spectroscopy, linear polarization and potentiodynamic polarization

measurements. Surface morphology of mild steel in the inhibited and uninhibited solution was

investigated by SEM. The results of this measurements display that the protective layer formed on the

mild steel surface which is evidence of inhibition. Hydrophilic and hydrophobic properties of mild steel

surface were investigated by contact angles measurement and the surface angles are increased during

inhibition present the protective layer was formed and decrease metals react with water and corrosive

materials.

The experimental results and electrochemical parameters illustrate that Rheum Ribes extracts

increases the corrosion inhibition of mild steel in 1 M HCI solution and the protection efficiency

increases.

Key Words: Rheum Ribes Flower, green plant extracts, mild steel, corrosion inhibition.

Ti6Al4V BİYOMEDİKAL İMPLANTLAR ÜZERİNE ELEKTROFORETİK

OLARAK DEPOLANAN HA/CTS BİYOKOMPOZİT KAPLAMALARIN

KOROZYON DİRENCİNİN İNCELENMESİ

Ali TOZAR*1, İsmail Hakkı KARAHAN1 1Mustafa Kemal Üniversitesi, Fen-Edebiyat Fakültesi, Fizik Bölümü, Antakya / HATAY / TÜRKİYE

Çoklu travmalar veya doğal yaşlanmadan dolayı insan vücudundaki kemiklerde en çok görülen

defekt kırılmalardır. Ortopedik cerrahide en sık kullanılan tedavi ise implantasyondur. Bu nedenle

biyomedikal alanda uygun metal ya da seramik malzemelere olan ihtiyaç gün geçtikçe artmaktadır.

Hastanın yaşam standartları açısından ise bir implantın uzun vade dayanımı oldukça büyük önem arz

etmektedir. Ti6Al4V alaşımları implantasyon için iyi bir alternatif olarak görülse de korozyona bağlı

olarak sağlığa zararlı metal salımı ve implant hatası riskleri halen tartışma konusudur. Bu tip

komplikasyonlar uygulanan implantın düzeltilmesi için revizyon cerrahisine ihtiyaç doğurur. Bu ise hasta

açısından istenmeyen bir durumdur.

Son yıllarda Ti6Al4V biyomedikal implantların, üstün kemik entegrasyonu nedeni ile hidroksiapatit

(HA) ile kaplanarak implantın biyouyumunu ve korozyon direncini arttırmaya yönelik kayda değer

çalışmalar yapılmaktadır. Ancak plazma sprey ve mikroark oksidasyonu gibi yüksek sıcaklık gerektiren

endüstriyel yöntemler HA’in çözünmesine neden olarak biyouyumluluğunu düşürmektedir. Elektroforetik

depolama oda sıcaklığında uygulanabilmesi, oldukça ekonomik olması ve kompleks yüzeylerin kolayca

kaplanabilmesi gibi avantajları sayesinde son yıllarda oldukça dikkat çekmeye başlamıştır.

Bu çalışmada biyomedikal Ti6Al4V alaşımları elektroforetik olarak hidroksiapatit/kitosan

(HA/CTS) biyokompozit malzemesiyle başarılı bir şekilde kaplanmıştır. Kaplama işleminde etanol,

isopropil alkol ve su içeren bir polielektrolit kullanılarak, kitosan konsantrasyonunun Ti6Al4V

alaşımların korozyon direnci üzerindeki etkisi elektrokimyasal karakterizasyon yöntemleriyle

incelenmiştir.

Şekil 4. Artan Kitosan konsantrasyonlarında elektroforetik olarak depolanan HA/CTS biyokompozit kaplamalarına ait Tafel

GALVANIC COUPLING BEHAVIOR BETWEEN TITANIUM BASED NITRIDE

COATINGS AND STEEL

Burcak AVCI1, Dilan ER1, Mustafa URGEN*1 1Istanbul Technical University, Metallurgical and Materials Engineering Department, Maslak / ISTANBUL /

TURKEY

Hard ceramic coatings such as TiN, CrN and TiAlN can be produced on various metallic

substrates by physical vapor deposition (PVD) techniques. Metallic substrate and ceramic coating

systems are commonly used to improve cutting, working and drilling tools. With PVD methods, wear,

corrosion and tribo-corrosion behavior of substrates are improved. However, PVD columnar structure and

intrinsic porosity of these coatings limits their usage as corrosion protective coatings. To improve their

corrosion resistance, few production strategies are used, such as coating in multilayers, adding corrosion

resistant layers in between the substrate and the coating and nanocomposite coatings. 

  Since these coatings are very good electronic conductors a possibility of establishment of  a

galvanic cell between the substrate and the coating is expected. In most of the studies conducted on

corrosion protective behavior of these coatings this possibility is almost always mentioned. However, to

our knowledge this interaction hasn’t been studied thoroughly. This study investigates the galvanic

interaction between steel and TiN, TiAlN coatings. TiN and TiAlN coatings are deposited on inert

alumina substrates by CA-PVD. Potentiodynamic tests are done for steel and nitride coatings in deareated

0.1 N HCl. The polarization curves are then overlaid depending on various anode to cathode ratios. Zero

resistance ammeter (ZRA) tests in the same medium are also conducted with the similar anode to cathode

ratios. Finally, an empirical relation between electrode polarization and galvanic current is established.

Key Words: Cathodic arc PVD (CA-PVD), galvanic cell, TiN, TiAlN.

ELOKSAL İŞLEMİ UYGULANAN ALÜMİNYUM ALAŞIMLARININ ASİDİK VE

ALKALİ ORTAMLARDA KOROZYON ÖZELLİKLERİNİN İNCELENMESİ

Fadime AKPINAR1, Furkan KALAN1, T. Çağrı ŞENOCAK1, Burak DİKİCİ1, K. Vefa EZİRMİK*1 1Atatürk Üniversitesi, Metalurji ve Malzeme Mühendisliği Bölümü, Yakutiye / ERZURUM / TÜRKİYE

Endüstriyel uygulamalar da yüksek dayanım-ağırlık oranı, iyi döküm özelliği ve düşük termal

genleşme özellikleri ile artan kullanım alanlarından dolayı, Al ve alaşımlarının korozyon direncini

arttırmak teknolojik açıdan büyük bir öneme sahiptir [1]. Alüminyumun üzerinde doğal olarak meydana

gelen ve koruyucu özelliğe sahip olan oksit tabakası, ince ve düzensiz bir yapıda bulunmaktadır.

Alüminyum ve alüminyum alaşımlarının saldırgan ortamlarda kullanımı sırasında bu oksit tabakasının

mekanik veya kimyasal olarak bozunması korozyon oluşumuna sebep olmaktadır [2]. Bu nedenle Al ve

alaşımlarının, yüzey özelliklerinin iyileştirilmesi gerekmektedir. Alüminyum ve alaşımlarının korozyon

direncini arttırmak için yüzey kaplamaları ve anodizasyon prosesi (eloksal işlemi) gibi çeşitli yüzey

modifikasyon teknikleri kullanılmaktadır. Ekonomik bir yöntem olan anodizasyon işlemi, yüzeyde

meydana gelen oksit tabakasının düzenli olarak büyümesine ve dolayısıyla korozyon direncinin

arttırılmasına katkı sağlamaktadır. Eloksal, alüminyum ve alaşımları üzerinde “alümina” olarak bilinen

koruyucu oksit tabakasının asidik elektrolit içerisinde elektrik akımı yardımıyla büyütüldüğü bir işlemdir.

Bu işlem sayesinde korozyon dayanımı ile birlikte sertlik ve aşınma direnci de iyileşmektedir [3].

Bu çalışmada AA-1050, AA-2024, AA-3003, AA-5083, AA-7072 ve AA-8079 alaşımlarının

korozyon dayanımını arttırmak için sülfürik asit ortamında eloksal işlemi yapılmıştır. Eloksal işlemi, 12-

25 volt potansiyel aralığında ve farklı sürelerde (30,45,60 dakika) gerçekleştirilmiştir. Numunelerin asidik

ve alkali ortamlardaki korozyon davranışları potansiyodinamik korozyon testleriyle karşılaştırmalı olarak

incelenmiştir. Korozyon öncesi ve sonrası yüzeylerde oluşan yapılar ve korozyon ürünleri optik

mikroskop, XRD, taramalı elektron mikroskobu ve EDS kullanılarak incelenmiştir.

EFFECT of CURRENT DENSITY on MATERIALS and CORROSION

PROPERTIES of FILMS PULSE ELECTRODEPOSITED FROM

PYROPHOSPHATE SOLUTIONS CONTAINING Cu and Zn IONS

Kağan YURDAL*, İsmail Hakkı KARAHAN

Hatay Mustafa Kemal University, Antakya / HATAY / TURKEY

Alloys containing copper and zinc, namely brass are ideal materials for many applications, including

corrosion protection, applications due to good mechanical properties, use as interlayer coating and substrate

material, hydrophobic surface formation. Another important property of this alloy system is “shape memory effect

(SME)”. Materials with shape memory property can be used in sensor and actuator applications.

Electrodeposition is a film fabrication technique which has many advantages such as possibility of

fabrication under athmospheric conditions and at room temperature, ease of laboratory and large scale fabrication.

Moreover, it has many process parameters, which can be used to obtain films with different properties. It is widely

used in fabrication of metallic coatings [1].

In this study, brass films were fabricated via pulse electrodeposition at different current densities ranging

from 5mA/cm2 to 50mA/cm2. Pyrophosphate based aqueous electrolytes were used. Electrolytes contained Cu and

Zn ion precursors to form Cu-Zn alloys. Each fabrication was carried out on two different kinds of steel substrates.

Plate substrates were used to make materials characterization including elemental composition, film morphology by

SEM, phase analysis by XRD. For corrosion tests, films with same process parameters were fabricated on steel

rods. Open circuit potential, electrochemical impendance spectroscopy (EIS) and Tafel experiments were employed

to reveal corrosion properties of coated steel specimens in 3.5wt% NaCl containing water medium. Effect of

deposition current density on resultant properties is discussed.

Endüstride kullanılan sentetik organik inhibitörlerin çevreye verdikleri zarar her zaman endişe

konusu olmuştur. Bu inhibitörler hayati öneme sahip bazı organlara, böbreklere veya karaciğere geçici

veya kalıcı hasarlar verebilmekte veya biyokimyasal bir süreci bozarak vücuttaki bazı bölgelerde,r enzim

sistemlerinde sorunlara neden olabilmektedir. Bu toksik etkiler, doğal ürünlerin çevre dostu ve zararsız

olan antikorozif maddeler olarak kullanılmasına yol açmaktadır. Ekolojik farkındalık ve katı çevre

düzenlemelerinin ve çevre dostu süreçlerin geliştirilmesine ihtiyacının artması nedeniyle, daha önce

uygulanan inhibitörlerin yerine toksik olmayan alternatiflerin geliştirilmesi bu çalışmanın konusunu

oluşturmaktadır [1-2].

The surgical applications in general surgery, microsurgery and many other clinics used that preparation and

maintenance in care of instruments and accessories for reusable instruments have a very important place in animal

hospital applications. In the light of research and development studies and guidelines, the most suitable product and

method should be selected for effective cleaning, disinfection and maintenance of instruments.

Today, stainless steel, which is frequently preferred by many sanitarians the production of medical

instruments are seen as a very strong material that is never eroded. When users are observe that stainless steel can

be mechanically eroded by heat, or by special chemicals, in a variety of ways, then they are surpised. However, if

we understand its properties and how to use it properly, it is possible to use these materials for a long time.

Particularly sensitive and small sized of the microsurgical instruments should be carefully prepared for reuse. The

most important cause of wear of medical instruments is the formation of corrosion, which leads to great problems

in the process of reuse and shortens the life span and may result in the end for use.

In this study, the corrosion resistance of the iodine solution used for the disinfection of the scalpel was

investigated by diluting 1/1, 1/50 and 1/300 ratios and the corrosion resistance evaluated at 30th and 60th minutes

by AC impedance technique. It has been observed that the corrosion resistance of the scalpel immersed in the of the

most increased dilution of iodine solution is better.

Keywords: corrosion, iodine solution, scalpel, empedans

Manisa Celal Bayar Üniversitesi, Akhisar MYO, Makine Bölümü, Akhisar / MANİSA / TÜRKİYE

Robotik tandem kaynağın en belirgin özelliği torcun içersinde konumlanan çift tel (tandem)

mekanizmasının olmasıdır. Bu sistem; tamamen robotik otomasyonla programlanabilen, birbirlerinden

bağımsız ve aynı anda iki telin iki farklı tel sürme düzeneği ile tek bir kaynak havuzunda birleşmesi

sonucu oluşan özel bir prosestir.

Günümüz makine imalat ve montajında verimlilik ve performans kriterleri göz önüne tutulduğunda

bu prosesin tercihi özellikle robotik kaynak uygulamalarında öne çıkmaktadır. Robotik kaynak

uygulamalarında doğru parametrelerin seçilmesi için işletmelerin yüzlerce deney yapmasına veya

istenilen parametreleri tek seferde tespit edebilme şansı, her zaman mümkün olması beklenilemez.

Özellikle, ince sacların gazaltı kaynak uygulamaları problemlidir. Bu çalışmada ince saclara robotik

tandem gazaltı kaynağı uygulanarak numunelerin mekanik ve elektrokimyasal korozyon özellikleri

karşılaştırılarak, en uygun kaynak ilerleme hız değişim aralıklarının tespit edilmesi amaçlanmıştır.

Bu çalışmada, robotik tandem gazaltı ark kaynağı (RT-GMAW) ile birleştirilen 3 mm kalınlığındaki

S235JR levhalardan elde edilen kaynaklı bölgelerin korozyon hızının değişimi araştırılmıştır. Kaynak

işlemi MG2 dolgu teli ve ARCO-10 koruyucu gaz ortamında CLOOS marka robotik kolun kumanda

mekanizması ile 100, 110, 120 ve 130 cm/da kaynak ilerleme hız (LWS) değerlerinde gerçekleştirilmiştir.

Kaynak ilerleme hız değişiminin korozyon hızına olan etkisi, Tafel ekstrapolasyon yöntemi uygulanarak

belirlenmiştir.

Numunelerin korozyona uğramayan ve uğramış yüzeylerin makro ve mikroskobik görünümleri

değerlendirilmiştir. Sonuç olarak, kaynak ilerleme hız değişiminin artmasıyla korozyon hızının da kısmen

arttığı gözlemlenmiştir.

Anahtar Kelimeler: tandem, gazaltı, elektrokimyasal, tafel eğrileri, kaynak ilerleme hızı.

Aluminum and its alloys have been widely used in various industrial applications because of its

inherent merits, such as low density, excellent electrical and thermal conductivity and relatively good

corrosion resistance. Aluminum exhibits corrosion immunity in aqueous environments due to the

formation of a thin passive oxide film on its surface. This oxide film is susceptible to dissolve in highly

acidic environments because of its amphoteric characteristic [1].

The most effective method for protecting metals against corrosion is the use of inhibitors.Recently,

use of low-cost and eco-friendly products such as extracted compounds from leaves or seeds as corrosion

inhibitors for aluminum increased [2].

The aim of this work is to study the effect of water extracts of two plants on the corrosionof

aluminum alloy in 1M HCl solution. The techniques employed for corrosion inhibition are gasometry,

tafel polarization and electrochemical impedance spectroscopy (EIS). Chemical gasometry technique

showed that addition of water extracts to 1M hydrochloric acid solution decreases the volume of the

hydrogen gas evolved. The inhibition efficiency obtained from chemical and electrochemical tests were in

good agreement, it increases with increasing concentration of water extracts. The potentiodynamic

polarization experiment revealed that the water extracts are inhibitors of mixed-type and electrochemical

impedance spectroscopy (EIS) confirmed that changes in the impedance parameters are due to surface

adsorption. Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS) study

confirmed that the inhibition of corrosion of aluminum is through adsorption of the extracts molecules on

the surface of metal.

Key Words: Plants extracts, Corrosion inhibition, Green inhibitor, Electrochemical, Aluminum.

POLYPYRROLE COATING by STATISTICAL EXPERIMENTAL DESIGN

Conductive polymers are one of the most popular study subjects of researchers working about

corrosion protection. However, since electrochemical synthesis of these polymers depends on many

parameters, some kind research studies can be completed in a long time. In addition, classical methods

have a very limited work area. Experimental design techniques are a very effective solution to solve this

problem [1]–[7].

In this study, concentrations of lithium perchlorate, which is used for support electrolyte, and (E)-

chalcone, which is used for additive, on corrosion and electrical resistance of the polypyrrole film

synthesized on AISI316L surface from acetonitrile medium and the connection between these results

were investigated. For this purpose, an experiment set was designed using 22 factorial design technique

with three replications as connected to additive and support electrolyte concentrations. The experiments

were performed with 3 replicates as designed and pyrrole concentration was to be constant at 0.1 M for all

synthesis baths in the designs. The difference between the concentrations was entered to the program as 2

times for each chemical and pyrrole concentration was kept constant at 0.1 M for all synthesis baths. The

polypyrrole films were synthesized on the AISI SS316L from the baths prepared according to the

designed experiment by cyclic voltammetry technique at a scanning rate of 50 mV/s. The corrosion

performances of the electrodes were monitored in 3.5% sodium chloride aqueous solution by AC

impedance spectroscopy (EIS) for 240 hours. Impedance data after 240 hours were obtained were

modeled as equivalent electrical circuits in the ZView2 software. The electrical resistances (Rdc) of the

synthesized polypyrrole films were measured by Four Point Probe technique. The electrical resistance and

calculated corrosion resistance (Rcorr) values were entered in response to the designed run. Then, the

experimental design was analyzed with 2FI model to generate 3D response surface graph.

As result of the study, it was found that the lithium perchlorate concentration, which is the support

electrolyte in the bath, was effective at 61.35% on Rdc and 76.11% on Rcorr; (E)-chalcone concentration

was found to be effective at 19.73% on Rdc and 3.37 on Rcorr. The change in the value of both

concentrations affects the Rdc by 18,06% and Rcorr by 3.25%. ANOVA analysis confirms this. The

increase in the lithium perchlorate concentration increases the electrical conductivity and corrosion

resistance of the polymer film in all (E)-chalcone concentrations, while the increase in the (E)-chalcone

concentration at low lithium perchlorate concentration increases the electrical resistance and decreases

corrosion resistance of the polymer film. The increase in the lithium perchlorate concentration increases

the electrical conductivity and corrosion resistance of the polymer film in all (E)-chalcone concentrations,

while looked at this behaviour in terms of (E)-chalcone concentration, similar behaviour is seen only at

high lithium perchlorate concentration. Like our previous study [4], the decrease in (E)-chalcone

concentration at low lithium perchlorate concentration leads to an increase in corrosion and electrical

resistance. As main result of the study, it was determined that SS/PPy+CHC polymer film had a direct

correlation between the corrosion resistance and its electrical resistance.

Key Words: (E)-chalcone, acetonitrile, pyrrole, corrosion, statistical design experiment, electropolymerization.

INVESTIGATION of CORROSION PERFORMANCE of POLY(o-ANISIDINE)

FILMS SYNTHESIZED ON ZnNi and ZnNiMo COATED COPPER SURFACE

Molybdenum is seen as one of the important metals of the future by the Turkish mining industry

due to its some superior properties. Molybdenum studies have begun to increase in the material literature

due to the fact that they are chemically similar to chromium, but hexavalent molybdenum is less toxic

than hexavalent chromium. However, molybdenum cannot electrochemically coat alone onto a surface, it

needs to form an alloy. Zinc and its alloys with 8B group metals are the most commonly used alloys for

this purpose [1–4]. In this study, the corrosion resistance of the poly(o-anisidine) thin films synthesized

on zinc nickel and zinc nickel molybdenum alloys was investigated.

For this purpose, copper electrode was coated with 5 µm thickness zinc-nickel (ZnNi) and zinc-

nickel-molybdenum (ZnNiMo) alloys at 30 mA/cm2 current density in the citrate-sulphate bath [2], [5].

After that, poly(o-anisidine) (PoA) films were synthesized onto anodically passivated alloy surface at 20

mV/s scan rate by cyclic voltammetry in sodium oxalate medium containing 10 mM molybdate salt and

70 mM o-anisidine. The metallic characterization of the coated and uncoated electrodes was carried out

by linear sweep voltammetry technique. Corrosion performances were monitored with anodic polarization

curves and A.C. impedance spectroscopy in 3.5% aqueous sodium chloride solution. Morphological

investigation of electrodes was carried out with scanning electron microscope.

From the results, it was observed that, corrosion resistance of thin PoA film, which was synthesized

on Cu/ZnNiMo surface, was higher than that of Cu/ZnNi/PoA electrode. When SEM images were

examined, it was observed that ZnNiMo surface was composed homogeneous globular crystals, ZnNi

surface was composed of leafy heterogeneous crystals. These crystal structures caused change the

morphologies and corrosion behaviours of the poly(o-anisidine) films on the surface.

Key Words: copper, zinc–nickel–molybdenum, corrosion, molybdate, o-anisidine, electropolymerization.

Korozyon, çevredeki malzemelerin kimyasal reaksiyonlar yoluyla aşamalı olarak yok edilmesi

veya bozulması olarak tanımlanmaktadır [1]. Endüstriyel yatırımların yanı sıra üretimin maliyetini

etkileyen en önemli faktördür [2]. Korozyon, birçok alanda olduğu gibi gıda endüstrilerinde de sorun

olmaktadır [3]. Gıdalar önemli miktarda su, organik asit, tuz, antosiyanin gibi bileşenler içermektedir.

Ancak bu bileşenler korozyona sebep olmakta veya hızlandırıcı rol oynamaktadır. Üründe meydana gelen

değişiklikler vakum kaybı, şişme ve sızıntıya neden olmaktadır. Ayrıca renk, doku ve duyusal

özelliklerini bozarak gıdanın görünüş, besin değeri ve raf ömrünü olumsuz etkilemektedir [4]. Dolayısıyla

korozyon kaynaklı hasarlarının zamanında saptanması ve ilerlemesinin kontrol altında tutulması

günümüzde önemli hale gelmiştir [2]. Literatürde gıda işletmelerinde karşılaşılan korozyon çalışmalarının

sınırlı kaldığı görülmüştür. Bu çalışmada son yıllarda gıda endüstrisinde yapılan korozyonlar çalışmaları

hakkında bilgi verilmesi amaçlanmaktadır.

Powder metallurgy (P/M) method is widely attracted on the producing of stainless steel parts due

to provide high quality property components and cheap to the other production methods[1,2]. P/M

stainless steels parts applied when required corrosion resistance and aesthetic appearance. In this study; as

stainless steel type; austenitic and martensitic stainless steels were used. Austenitic stainless steel has at

least 10.5%Cr and principally austenite phase and presents good corrosion resistance and mechanical

properties, however, there is a high sensitivity to local corrosion in chloride mediums [3]. Martensitic

stainless steels have 11-14wt%Cr and 0.6wt%C and also possess industrial areas such as pumps, mixers

of chemical products where operating under corrosive environments [4].

In this study; the corrosion performances of austenitic and martensitic stainless steels prepared by

powder metallurgy method have been performed. Firstly; X2CrNiMo17-12-2 austenitic staınless steel and

X12Cr13 martensitic stainless steel were pressed on the 400 and 600MPa pressures using traditional

pressing technique and the pressed austenitic and martensitic stainless steel specimens were sintered at

1200°C temperature for an hour under Ar atmosphere. The corrosion performances of these stainless steel

specimens have been examined in 3.5% NaCl by using EIS and polarization techniques.EIS measurement

was performed for each 2 ,96 h and end of the 96 h current-potential curves were taken. These

measurements have been supported with scanning electron microscope (SEM) images, Energy Dispersive

X-ray Spectroscopy (EDS).

Key Words: Powder metallurgy, austenitic stainless steel, martensitic stainless steel, heat treatment,

corrosion resistance.

ELECTROCHEMICAL BEHAVIOR OF Ti6Al4V ALLOY IN SALT WATER AND

SIMULATED BODY FLUID

Ti6Al4V alloys are metallic materials used in the manufacture of load bearing implants, especially

in the hip and knee joints, and in dental implants. The excellent properties such as strength / density ratio,

modulus of elasticity, corrosion resistance, biocompatibility, etc., increase their use.

The biocompatibility of metal parts is related to their corrosion in the body. Because the human

body contains various ions such as water, dissolved oxygen, protein, chloride and hydroxide, it creates a

very corrosive environment for metals and alloys used as biomaterials. Metallic materials are weakened

by corrosion in the body fluids, and more importantly, corrosion products can penetrate into the tissues

and damage the cells. For this reason, it is necessary for the implant materials to have a high corrosion

resistance and not be damaged due to surface deterioration in terms of patient health. The implant surface

is directly in contact with the living tissues in the body, and the tissue-implant interactions are dependent

on the surface properties of the implants. It is very rare that metallic-based biomaterials with good mass

properties have suitable surface characteristics at the same time.

In our study, the corrosion behavior of Ti6Al4V alloy have different surface roughness was

investigated electrochemically in salt water and simulated body fluid. Potentiodynamic polarization

method was used in electrochemical tests. Corrosion rate was calculated from corrosion current density

and the values in both environments are compared with each other. The metal surface was examined by

scanning electron microscopy.

Key Words: Ti6Al4V, simulated body fluid, electrochemical corrosion experiment.

bir seçenek haline getirmiştir. Kompozit malzemeler, mukavemet/hafiflik oranlarının yanında yüksek

aşınma direnci ve korozif ortamlara olan yüksek dayanımları neticesinde, aşınan yüzeyler üzerinde ve

farklı şartlandırılmış ortamlarda kullanılabilirliğiyle de ilgi uyandırmaktadır. Tribolojik performans olarak

adlandırılan bu özellikleri, farklı takviye elemanları (cam, karbon, bazalt elyaf vb.), matris türleri (epoksi,

polyester, polipropilen, polivinilester vb.) ve matris içerisine yapılan parçacık katkıları (makro boyutta

dolgu malzemeleri, nano parçacıklar) sayesinde geliştirilebilmektedir. Polimer matrisli bir kompozit

malzemede, en basit kusurların matris malzemede görünme ihtimalinin daha yüksek olduğu

düşünüldüğünde; matris malzemede yapılan performans arttırıcı bir modifikasyon, aynı zamanda tüm

kompozit malzemeyi iyileştirebilmektedir.

Polimer matris modifikasyonunda, son yıllarda en çok kullanılan yöntemlerden biri de nano

parçacık ile matris malzemeye katkıda bulunmaktır. Bu çalışmada, kompozit malzemenin mekanik ve

termal özelliklerini arttırıcı bor nitrür (BN) nano takviyesi kullanılarak epoksi matrisli kompozit malzeme

(BN/Epoksi Kompozit) üretimi yapılmıştır. BN nano parçacığının seramik yapısından faydalanılarak

üretilen kompozit malzemenin aşınma özelliklerinin arttırılması amaçlanmıştır. Korozif ortama uyumu da

bilinen epoksi matrisli, BN nano parçacığı ile takviye edilen kompozit malzeme, şartlandırılmış asitli

ortama 21 gün süreyle bırakılarak, belirli zaman aralıklarında aşınma özellikleri kontrol edilmiş ve

normal ortama göre kıyaslamaları yapılmıştır. Hem normal ortamda hem de asit ortamında bekletilen

kompozit malzemelerin aşınma testleri pin on disk aşınma test cihazında sabit bir hızda ve üç farklı yük

altında, kuru ortamda gerçekleştirilmiştir.

Anahtar Kelimeler: Bor nitrür, pin on disk, aşınma, epoksi, asidik ortam.

Elyaf takviyeli kompozit malzemelerde yaygın olarak kullanılan cam, karbon ve aramid elyaf

tiplerinin tamamının petrol kaynaklı olmaları hem endüstriyel hem de akademik çalışmalarda

araştırmacıları doğal kaynaklardan elde edilebilecek elyaf çeşitlerini araştırmaya yönelterek,

sürdürülebilir kompozitlerin geliştirilmesi konusundaki çalışmaları arttırmıştır. Yer kabuğundaki

çatlaklar, yarıklar ya da volkan bacaları aracılığı ile yeryüzüne çıkan magmatik bir kayaç olan bazalttan

üretilen bazalt elyaf, mineral kaynaklı olması sebebiyle son yıllarda polimer kompozitlerde kullanılan

önemli elyaf takviyelerin başında gelmektedir. Bazalt elyaf, gelişmiş mekanik özelliklerinin yanında

kimyasal direncinin yüksek olması sebebiyle özellikle korozif ortam şartlarındaki mühendislik

uygulamalarında tercih edilmekte, bu durum bazalt kompozitlerin mekanik ve aşınma testlerinin gerçek

şartlara benzer korozif ortamlarda yapılması konusundaki gerekliliği ve ihtiyacı ortaya koymaktadır. Bu

ihtiyaçtan yola çıkarak, çalışmada korozif ortamın bazalt elyaf takviyeli epoksi kompozitlerin mekanik

özellikleri, sürtünme ve aşınma davranışları üzerine etkileri araştırılmıştır. Numuneler ortam sıcaklığında,

pin on disk aşınma test cihazında sabit hızda, iki farklı yük altında aşınmaya maruz bırakılmıştır.

Kompozit malzemeler kuru ortamda mekanik ve aşınma testlerine tabi tutulmuş, daha sonra 21 gün

boyunca korozif çözeltide bekletilmiş, belirli aralıklarla da testler tekrar edilmiştir. Çekme numunelerinin

kırılma yüzeyleri mikroskop görüntüleriyle incelenmiş, aşınma testleri sonunda aşınma yüzeylerinde

meydana gelen hasar mekanizmaları ise SEM görüntüleri yardımıyla yorumlanarak, bazalt elyaf takviyeli

epoksi kompozitlerin farklı korozif ortamların etkisindeki aşınma dirençleri birbiriyle kıyaslanmıştır.

Anahtar Kelimeler: Aşınma, bazalt elyaf, epoksi, korozif ortam.

INVESTIGATION OF THE CORROSION PROPERTIES OF ANODIZED AZ31

MAGNESIUM ALLOYS

Recep ÇATAR*1, Hikmet ALTUN2 1Bayburt University, Mechanical Engineering Department, Bayburt/ TURKEY

Anodizing is one of the most commonly applied coating processes to protect Mg alloys from

corrosion. In this study, anodization were applied to AZ31 Mg alloys in three different solutions of 1 M

NaOH, based on silicate (5 g/l Na2SiO3 + 5 g/l KOH) and phosphate (5 g/l Na3PO4 + 5 g/l KOH) solution.

AZ31 Mg alloys were anodized in a 1 M NaOH solution at 100 V constant voltage for 10 minutes while

in silicate and phosphate based solutions were anodized at constant current of 0,140 A/cm2 to final

voltage of 450-470 V. As a result of the anodizing processes, ceramic coatings were obtained in all three

solutions. The electrochemical properties of anodized Mg alloys were determined by potentiodynamic

polarization method in 3,5% NaCl solution. The chemical composition and phase structure of the coating

were determined by scanning electron microscopy (SEM), electron dispersion X-ray spectroscopy (EDX)

and X-ray crystallography (XRD). As a result of the analysis, it is seen that the coating in the NaOH

solution is composed of the MgO compound at a high level, whereas the Mg2SiO3 and Mg3(PO4)2

compounds are also formed in the silicate and phosphate based solutions in addition to the MgO

compound, respectively. When the results of the electrochemical test are examined, the highest corrosion

resistant in silicate based solution is observed and at least the in NaOH solution is found.

Key Words: AZ31 Mg alloy, anodizing, corrosion

DAYANIMININ ARTTIRILMASI

Okay ÖZÜPEK*1, Ömer Faruk ÖZKAN1, Mümin ÇITAK1 1 Kar-El Demir Tel San Tic. Ltd. Şti. Aliağa / İZMİR / TÜRKİYE

Sıcak daldırma galvanizleme işlemi demir çelik ürünlerini korozyona karşı korumak için maliyeti

ve uygulanabilirliği sayesinde en yaygın kullanılan bir yöntem olmuştur. Sıcak daldırma galvaniz ile

kaplanan çelik ürünlerde yüzeydeki çinko demire göre daha aktif olduğu için ortamda önce oksitlenerek

demirin korunmasını sağlar (katodik koruma). Artan maliyetler ve azalan hammadde kaynakları sebebiyle

SDG ürünlerin daha uzun süre dayanması için farklı alaşım ve kimyasallar uygulanarak korozyon

dayanımları arttırılmaktadır. Bu işlemlerden biriside kromatlamadır (pasivasyon). Bu işlem daha önce

çelik teller üzerinde uygulanmamıştır.

Bu çalışmada SAE 1006/1008 kalite filmaşinlerden çekilen 2,50mm, 3,00mm çelik tellerin SDG

işleminde çinko havuzundan sonra uygun kimyasal havuzuna daldırılmasıyla yüzeyindeki serbest çinko

pasive edilerek yüzeye uygun kromat tabakası kaplanması sağlanıp ve pasivasyon prosesinin çelik teller

üstüne uygulanabilirliği incelenmiştir. Alınan numunelere yapılan tuz testleri sonucunda standart üretim

SDG tellerin pasivasyon işleminden sonra korozyon dirençlerinin arttığı gözlenmiştir.

The mild steel (MS), has been widely used in many industries, due to some properties such as,

affordability in economy and simple smelting process. The crucial problem of mild steel is that it is easy

to be corroded in acid pickling process, causing severely financial and industrial losses [1]. Especially in

closed-circuit systems and cleaning process, an effective way of protection of MS against corrosion, is the

addition of corrosion inhibitors. For this purpose, 2,6-pyridinedicarboxylic acid (PDCA) was used as

inhibitor in several concentrations (0.5, 1, 5 and 10 mM) in 0.5 M HCl and the corrosion behavior of MS

in absence and presence of PDCA, was investigated with the help of electrochemical impedance

spectroscopy and polarization measurements. Surface morphology was monitored by optical microscope.

The potential zero charge (pzc) measurements were obtained. The contact angles of water drop of surface

were determined by optical tensiometer. The Young-Laplace equation was used for calculations. The

quantum chemical calculations were achieved via DFT with the B3LYP/6-311++G (d, p) basis set. The

results showed that; adsorption of PDCA obeyed Langmuir isotherm, the inhibition efficiency (η) values

were 80.6 and 82.6% in presence of 10 mM PDCA, after 1 and 168 h immersion periods, respectively.

The corrosion inhibition and adsorption characteristics of the extract obtained from the plant

papaver somniferum L (PSL) by electrochemical methods at differet temperatures (25, 35 and 45 °C)

were investigated in 0,2 M HCl and 0,2 M HCl + x ppm PSL solutions on AISI 304 stainles steel (AISI

304 SS), ETIAL 150 aluminum alloy (ETIAL 150 Al) and copper. The best inhibition were obtained

containing 0,2 M HCl + 500 ppm PSL inhibitor concentration solutions. Surface observations of metals

after standing experiments were investigated by atomic force microscopy (AFM), scanning electron

microscopy (SEM) and energy scattering X-ray method EDX). The inhibition effect is increased with

increasing inhibitor concentration. Extract adsorbed on the surface of metals obeyed Langmuir

adsorption isotherm. Langmuir adsorption isotherms confirm the physical adsorption mechanism and the

inhibitor is a mixed type inhibitor. SEM images show cracks and pitting on the surfaces in extract free

solutions. AFM and SEM show thick dense film on metal surfaces in containing extract solutions. The

occuring film closed all the active corrosion sites on metals and inhibited corrosion mechanism. Some

thermodynamic and kinetic parameters for the adsorption process; Adsorption equilibrium constant

(Kads), Gibbs adsorption free energy (Gads), activation energy of corrosion reaction (Ea) were calculated

and discussed by using Tafel results. Arrhenius energies increased with increasing inhibitor

concentration. Activation energies and Gibbs free energies for the inhibition reactions were supported the

physical adsorption mechanism.

The corrosion inhibition properties of thiazole derivative (TZ) were investigated by weight loss,

electrochemical impedance the electrochemical impedance spectroscopy (EIS) and potentiodynamic

polarization methods. The results of electrochemical research revealed that the TZ was an effective

inhibitor in HCl medium. Tafel curves reveal that TZ was adsorbed on the metal surface by adsorption

mechanism and behave as mixed type inhibitor [1]. With the aim of extracting the parameters of the

electrochemical impedance spectroscopy an appropriate equivalent circuit model was offered. The

inhibition efficiency, η(%), increased with the increase in concentration inhibitor. The Among TZ

exhibited maximum efficiency of 95% at 10-3M. Langmuir adsorption isotherm was well fitted for the

adsorption of the inhibitor tested on carbon steel surface with a competitive physisorption and

chemisorption mechanism [2]. The temperature dependence of inhibition efficiency was explained by

considering thermodynamic parameters of adsorption and kinetic parameters of corrosion. The inhibition

mechanism was analyzed by the potential of zero charge (Epzc) measurement at the solution/metal

interface. The adsorption behaviour of the inhibitors tested on Fe (110) surface was investigated by

Monte Carlo simulations to verify their corrosion inhibition efficacies. Molecular dynamic simulation

revealed that the molecules can adsorb strongly onto the surface of iron in a near flat orientation.

Epoxy resins, a very important class of thermosetting polymers, are extensively used as a coating

material to protect the steel structures from corrosion [1].

In this work, polyaniline nanocomposites containing inorganic oxide nanoparticles such as TiO2

and ZnO nanocrystallites with different ratios (0.1 g and 1.0 g) on stainless steel surface were synthesized

through chemical polymerization in the presence of aniline and ammonium persulfate oxidant. The

resulting polymeric nanocomposites have been characterized by means of Fourier transform infrared

(FTIR) spectroscopy, X-ray diffraction pattern (XRD) methods. Microstructures of samples are analysed

by scanning electron microscopy (SEM). Moreover, transmission electron microscopy (TEM) was

employed to characterize PANI/ZnO and PANI/TiO2 polymeric nanocomposites. Also, thermal properties

were determined by thermal-gravimetric analysis (TGA) and differential scanning calorimetry (DSC).

PANI/ZnO and PANI/TiO2 nanocomposites were mixed with polyvinyl butyral (PVB) through a solution

mixing method. The obtained polymeric nanocomposites and epoxy resin applied in compliance with

technological rules in the polyaniline matrix for improving its mechanical and barrier properties. The

coated stainless-steel substrates were investigated using potentiodynamic (Tafel) polarization technique

and electrochemical impedance spectroscopy (EIS) in 3.5 wt% NaCl. The surface morphology of the

PANI/Epoxy/nano metal oxide thin films were evaluated by scanning electron microscopy (SEM) studies.

The results of this study clearly showed that PANI/Epoxy/metal oxide polymeric nanocomposite coatings

outstanding protected steel against corrosive environment even at low concentration.

ELECTROCHEMICAL STUDIES OF 4-((4-BROMOBENZYLIDENE)AMINO)

BENZAMIDE (4-BAB) AS AN EFFICIENT CORROSION INHIBITOR FOR MILD

STEEL IN 1.0 M HCl

In many of corrosion studies, hydrochloric acid is used which has advantages including low-cost,

ease of use, and efficiency in contrast to mineral acids. However, because of the strong corrosive behavior

of hydrochloric acid, a protective surface layer for mild steel is inevitable [1]. Recently, researchers have

focused on designing of materials that can serve as protective layers on steel surface aiming to reduce the

rate of corrosion during industrial operations including pipeline systems, drilling, and processing of oil

and gas. For this purpose, a variety of organic inhibitors have been used including N, O and S atoms [2].

In the present work, a new S containing Schiff base 4-((4-bromobenzylidene)amino) benzamide (4-BAB)

was synthesized. The corrosion inhibition of 4-BAB on mild steel was studied in 1.0 M HCl solution

using conventional electrochemical methods such as potentiodynamic polarization, electrochemical

impedance spectroscopy (EIS), and linear polarization resistance (LPR). The obtained EIS and LPR

results showed that inhibition efficiency (η%) of 1.0 mM 4-BAB 93.4%, 94.5 %, respectively. The

corrosion rate was calculated 0.876 mg cm-2 h-1 by potentiodynamic polarization.

DLC having special properties such as chemical inertness, high hardness, low friction, high wear

resistance and corrosion resistance is extensively used in applications such as protective coatings [1]. In

present work, TiO2 nanotube (NT) was synthesized by the two-step anodization technique. Diamond like

carbon (DLC) was coated on the surface of as prepared TiO2-NT using MicroWave Electron Cyclotron

Resonance plasma system (MW ECR) at 7.5 min. The morphology, composition and structure of the

electrodes were examined by field emission scanning electron microscopy (FE-SEM), energy dispersive

X-ray spectroscopy (EDX) and X-ray diffraction (XRD). The results showed that when DLC was coated

on the surface of TiO2-NT, the top of nanotubes were partially open and the pore diameter of hexagonal

structure decreased from 64.6 nm to of 44.9 nm. On the other hand, the microhardness test and contact

angle measurements revealed that additions of DLC carbon have a positive effect on the mechanical

properties of TiO2-NT film. Corrosion behavior of TiO2-NT and DLC-TiO2-NT electrodes in Hank's

solution at 37 °C was investigated using open circuit potential, electrochemical impedance spectroscopy

(EIS) and potentiodynamic polarization techniques. EIS was used to monitor the corrosion evolution over

20 days in Hank's solution at 37 °C.

ROLE OF ECOLOGICAL INHIBITOR ON ABRASION CORROSION OF

STAINLESS STEEL IN POLLUTED PHOSPHORIC ACID

In the wet production phosphoric acid industry, the acid produced contains various impurities,

including halides, metal cations, and gypsum particles. As a result, stainless steels, commonly used, are

subjected to the combined action of corrosion, due to chemical impurities (F-, Cl-), and abrasion related to

solid particles of suspended gypsum[1]. The corrosion-abrasion of stainless steels is a complex

phenomenon. It depends on the nature of the material-environment interface, the physicochemical

properties of the passivity film and the characteristics of the impact. Often the potential of stainless steels

is due essentially to their ability to form protective layers on their surfaces. Thus the action of abrasion

causes a partial or total depassivation, reducing the protective power of the passive layers [2]. The use of

corrosion inhibitors is an original way to control the abrasion-corrosion of metals. The latter evaluated by

potentiodynamic measurements and the surfaces analyzed by UV-Vis-IR and SEM-EDX techniques.

Potentiodynamic electrochemical measurements indicated that the inhibition efficiency improves with the

presence of clay and that it is of the anodic inhibitor type. The UV-Vis-IR analysis indicates that the

amplitude of the absorption bands increases in the presence of an inhibitor which reveals the protection of

passive layer formed.

ETİLEN GLİKOLÜN %3.5 NaCl ORTAMINDA St37 ÇELİĞİNİN KOROZYON

MEKANİZMASINA ETKİSİNİN ARAŞTIRILMASI

Fatima Erman BAĞCI*1, Hüsnü GERENGİ1, Ertuğrul KAYA1 1Düzce Üniversitesi, Mühendislik Fakültesi, Korozyon Araştırma Laboratuvarı, DÜZCE / TÜRKİYE

Su ve atmosfer koşulları altında metal ve alaşımları korunma yapılmadığı takdirde korozyona

uğramaktadır. Korozyona uğrayan metal ve alaşımları geri dönülemez bir yola girerek çevre, sağlık ve

ekonomik olarak oldukça büyük maliyete neden olmaktadır [1]. Düşük karbon çeliği (St37), düşük

maliyeti ve yüksek üretimi nedeniyle metaller içerisinde yaygın olarak kullanılmaktadır [2]. İnşaat

sektöründe, makine yedek parçalarında ve otomobil radyatör ve parçalarında kullanılan St37 çeliği

klorürlü ortamda oldukça fazla korozyona uğramaktadır [3]. Metal ve alaşımlarını korozyona karşı

korumak için en ekonomik yol inhibitör kullanmaktır. İnhibitörler bulundukları ortamda genellikle

değişmeden kalmaktadır ve metal yüzeyini kapatarak metalin bulunduğu ortamla ara yüzeyinin direncini

arttırmaktadır [4]. Etilen glikol motor soğutucu sistemlerinde yaygın bir şekilde kullanılmaktadır ve

soğutucu sistemler genellikle klorür içerdiğinden soğutma sıvısı sisteminde kullanılan metallerin

korozyonunu arttırdığı bilinmektedir [5-7]. Bu çalışmada; etilen glikolün 25 oC de %3.5 NaCl ortamında

St37 çeliğinin korozyon mekanizmasına etkisi, 6 hafta boyunca kütle kaybı yöntemi ile araştırılmıştır

(Şekil 1). Elde edilen bulgular, 6 hafta sonunda %3.5 NaCl çözeltisi içerisinde bulunan St37 çeliğinden

yapılmış kuponların ortama ilave edilen etilen glikolün etkisiyle daha az korozyona uğradığını

göstermektedir. Kütle kaybı yöntemi kullanılarak elde edilen verilere göre metal yüzeyinde bariyer

oluşturan etilen glikol, St37 çeliğinin %3.5 NaCl ortamındaki korozyon mekanizmasını %85.26 oranında

inhibe ettiğini göstermektedir.

Korozyon inhibitörü olarak genellikle organik inhibitörler tercih edilse de [1-2], bu maddelerin

çoğu pahalı, çevre ve insan sağlığı için toksik özelliğe sahip olduklarından pratikte kullanımlarını

kısıtlamaktadır. Günümüzde; çevre dostu doğal ürünlerin antikorozif maddeler olarak kullanılabilirlikleri

ile ilgili çalışmalara önem verilmektedir [3].

Bu çalışmada yumuşak çeliğin korozyonuna, ekonomik değeri olan çevre dostu bazı doğal atıkların

inhibisyon etkisi araştırılmıştır. Bu amaçla, Cucurbita Maschole kabuğunun (balkabağı) 1,0 M HCl

çözeltisinde yumuşak çeliğin korozyonuna inhibisyon etkinsi Eocp-zaman, potansiyodinamik polarizasyon,

lineer polarizasyon direnci ve elektrokimyasal impedans spektroskopisi tekniklerinden yararlanılarak

araştırılmıştır. Metal yüzeyinde oluşan filmin karakterizasyonu SEM-EDX, AFM ve temas açısı

ölçümleri ile yapılmıştır. Elektrokimyasal ölçümlerin sonuçları Cucurbita Maschole kabuğunun 1,0 M

HCl çözeltisinde etkin bir inhibitör olduğunu göstermiştir. SEM ve AFM çalışmalarından yüzeyde oluşan

koruyucu bir filmin metalin çözünmesini yavaşlattığı tespit edilmiştir.

Titanium and its alloys are very used in chemical industries, because of their corrosion resistance.

This resistance is due to the formation of an oxide film on their surfaces. The nature of the oxide film is

very controversial and depends on its formation technique.

The aim of the present work is to study the nature of the formed film on Ti-Cu (2%) by anodization

process in phosphoric acid 5M at different imposed potentials. The range of applied potential extends

from 200 to 1200 mV/SCE using a three electrode cell and from 5V to 35 V using a two electrode

configuration.

Nature of the obtained films are analyzed by X ray diffraction, their composition as well as the

oxidation state of titanium were investigated by XPS and EDS measurements. We have also study the

evolution of the thickness of the formed films with the applied potential in range of 5 to 35 V.

It is found that the film formed on the anodized surfaces is amorphous and thickens when the

applied potential increases. Thus, the oxidation state of titanium depends on the applied potential:

Mixture of Ti3+ and Ti4+ oxidation states when the anodization occurs at lower range of applied potential (

200 to 2000 mV/ SCE) while Ti4+ oxidation state becomes dominant at higher applied voltage.

Equivalent electric circuit of the formed film was investigated by electrochemical impedance

spectroscopy.

Key Words: Titanium, mott schottky, anodization, characterization.

PASLANMAZ ÇELİĞE KAPLANMIŞ POLİ(PİROL-KO-o-ANİSİDİN)KİTOSAN

KOMPOZİT FİLMİNİN KOROZYON PERFORMANSININ BELİRLENMESİ

Süleyman YALÇINKAYA*1, Didem ÇAKMAK1 1Mustafa Kemal Üniversitesi, Kimya Bölümü, Antakya / HATAY / TÜRKİYE

İletken polimerler, elektropolimerizasyon yöntemi ile doğrudan metal yüzeyinde ince ve homojen

filmler oluşturabilirler. Bu polimerlerin filmlerinin paslanmaz çelik yüzeyinde iyi bir korozyon

performansı sağladığı birçok çalışmada belirtilmiştir[1]. Bilindiği gibi çeliğin yüzeyinde bulunan doğal

krom(III) ve nikel oksit tabakası metali koruyucu bir etki sağlamaktadır. Ancak, bu tabaka oldukça poröz

bir yapıya sahip olduğundan özellikle Cl- gibi aktif iyonlar zamanla çukurcuk korozyonuna sebep olmakta

ve metalin bozulmasına yol açmaktadırlar. Buna karşın metal yüzeyine kaplanan iletken polimerler

yüzeyde bariyer etkisi yanında, gösterdikleri katalitik etki sayesinde metale anodik bir koruma

sağlamaktadırlar [2]. İletken polimerlerin özelliklerini geliştirmek için en çok başvurulan yollardan biri

kopolimer ve kompozitlerini hazırlamaktır. İletken polimerlerin kitosan gibi biyopolimerlerle kompozit

filmleri elde edilerek, sensör uygulamalarında destek materyal olarak kullanımıyla ilgili çalışmalar

literatürde mevcuttur [3]. Bunun yanında yapılan önceki çalışmalarda iletken polimere biyopolimer

katılarak elde edilen kompozit filminin oldukça homojen bir yapıda olduğu ve termal kararlılığının iletken

polimer filmine göre daha iyi olduğu belirtilmiştir[4]. Bilindiği gibi termal kararlılığın arttırılması

atmosferik korozyon açısından da oldukça önemlidir.

Bu çalışmada, poli(pirol-ko-o-anisidin)/kitosan kompozit filmi paslanmaz çeliğe dönüşümlü

voltametri tekniği kullanılarak kaplanmıştır. Kaplama işlemi 0,1 M monomer çözeltisi (pirol:o-anisidin

monomer oranı 1:1) katılmış 0,3 M okzalik asidin sulu çözeltisinde gerçekleştirilmiştir. Kompozit filmin

korozyon davranışları % 3,5 NaCl çözeltisinde EIS ölçümleri ve anodik polarizasyon eğrileri yardımıyla

araştırılmıştır. Elde edilen sonuçlar kompozit filminin iyi bir korozyon performansına sahip olduğunu

göstermiştir.

A NOVEL METHOD OF IMPROVED CORROSION RESISTANCE FOR STEEL:

ARTIFICIAL SUPERHYDROPHOBIC SURFACES PRODUCED BY NICKEL

Superhydrophobicity refers to the condition of extreme water repellency, characterized by water

contact angle (CA) greater than 150⁰. By making surfaces superhydrophobic, self-cleaning and anti-icing

properties of the material are improved.

With this study, we proposed a corrosion resistance improvement mechanism by producing

hierarchical structures on the metal surface. Two distinct approaches are taken. First one is to create a

rough structure on a hydrophobic surface (CA > 90⁰) and the second is chemically modifying properly

roughened surface with a material with low surface energy. Superhydrophobic coatings are deposited on

the electrolytic nickel coated steel substrate in three steps: Nickel is deposited on steel substrate

galvanostatically (5-6 A/dm2) for different times (5, 10 and 15 minutes). At the end of the coating process

surface morphology and coating thickness are characterized with SEM and XRF, respectively.

Afterwards, nickel coated steel substrate is anodically oxidized in molten KOH to obtain flower-like

hierarchical surface texture. Anodic oxidation of nickel plated samples are performed for 15 minutes at

200 oC. The surface texture of anodized sample characterized with SEM. Finally, chemical modification

of the anodized sample is completed by immersing into an ethanol stearic acid solution (0.01 mol/L) at

room temperature for 5 hours. After modification, FTIR analysis of the sample indicated the grafting of

stearic acid onto the surface. Moreover, static contact angle measurement is conducted and the contact

angle greater than 150⁰ is attained. Additionally, salt spray test results for 24 hours show that the

corrosion resistance of the produced superhydrophobic steel samples are improved by considerable

amount in neutral media.

Key Words: Superhydrophobicity, Nickel electroplating, Anodic oxidation of nickel, Steraric acid treatment,

Contact angle (CA).

INVESTIGATION of CORROSION RESISTANCE of POLYPYRROLE FILM

SYNTHESIZED WITH LIMONENE ADDITIVE ON AISI 316L STEEL

A. Tuncay OZYILMAZ, Ibrahim FILAZI*, Ersen GOKTURK, Yusuf REYHANOGLU, Cagla SURMELIOGLU

AISI 316L stainless steel (SS316L) is an alloy that is commonly used by the industry because of its

many superior properties. Although it successfully fulfills this anticipated alloy task to be resistant to

severe corrosive conditions, the metallic structure of the alloy requires more effective protection methods

in the long run. Conductive polymers are one of the most important research topics in the primary

literature to solve this problem. There are many successfully studies in the literature aimed at the use of

conductive polymers for the protection of SS316L from corrosion. One of the big advantages of polymers

is that different ions can be trapped in the matrix structures. In this way, corrosion resistance of

conductive polymers can be increased. This study aimed to increase the corrosion resistance of polymer

thin film by adding limonene to polypyrrole synthesis medium. Studies in the literature show that

limonene provides a successful inhibition effect at acidic corrosive conditions [1]–[7].

For the limonene added polymer thin film synthesis, limonene (Aldrich) at low concentrations

between 5 and 50 mM was added into the synthesis medium of acetonitrile containing 0.15 M LiClO4 and

0.1 M pyrrole. From this medium, a thin PPy and Lim+PPy films were synthesized on SS316L by cyclic

voltammetry technique applying scan rate of 50 mV/s. Corrosion performance of the obtained SS/PPy

and SS/Lim+PPy electrodes was evaluated in artificial seawater by AC impedance and anodic

polarization curve techniques. Also, structural characterization of polymer films was investigated by

FTIR and electrical resistance of films measured by Four Point Probe at 20 °C.

Figure 1. Chemical structure of limonene (dipentene)

As a result, it has been found after 192-hour immersion time in corrosive environment that the

corrosion resistance of the SS electrode coated with PPy film containing limonene (SS/Lim+PPy) is

rather high when compared with that of the SS/PPy electrode. The increase in limonene concentration has

been observed to slightly reduce corrosion resistance. When the electrical resistance is considered, it was

observed that the limonene additive increases the resistance.

Key Words: corrosion, SS316L, limonene, polypyrrole.

Corrosion is loss of metal caused by chemical, electrochemical, or biological reactions between the metal

and its surroundings and it is recognized as one of the most serious problems. Approximately1 to 6% of

the gross national product (GNP) of each nation goes to the annual corrosion costs [1-2]. The most

significant practical methods available for control of corrosion are i) protection related to materials(choice

of materials, appropriate design, conditioning the metal (protective coating and alloying)), ii) protection

related to medium (use of inhibitors), iii) protection with electrical applications (cathodic protection,

anodic protection). There is a lots of study on corrosion inhibitors that are less toxic and biodegradable

compared to current formulations. Green inhibitors displaying substantially improved environmental

properties will be the inhibitors most widely used in the future [3]. The present work is designed to

investigate the effect of tannic acid (TA), gallic acid (GA), ascorbic acid (AAc) and polyaspartic acid

(PASA) as green inhibitors for the corrosion inhibition of mild steel in decarbonized water as alone as a

binary mixtures and ternary mixtures by electrochemical techniques such as anodic and cathodic

polarization curves and electrochemical impedance spectroscopy (EIS). Corrosion behavior of mild steel

was investigated in the absence and presence of inhibitors in order to determine the optimum conditions.

EIS data was also analyzed by fitting to an equivalent electrical circuit model. Results suggested that

green inhibitors individually show high inhibition efficiency for mild steel corrosion in decarbonized

solution. Mixing of inhibitors for corrosion protection resulted in synergistic effect in case of only TA

and PASA mixture.

absence and presence and TA and PASA at pH=10.5.

cooling water systems, corrosion inhibition, electrochemistry.

Corrosion of drinking water system components and plumbing is the main source of metallic

elements (lead, copper, cadmium, zinc, ...) in drinking water, and consequently a source of contaminants

to consumers and degradation of water quality [1]. Among the materials widely used in this system is

brass because of its very good corrosion resistance, durability, and cost[2]. The aim of our work is the

study the effect different concentrations of the chloride on the behavior of brass in artificial drinking

water. The latter evaluated by electrochemical measurements and analyzed by scanning electron

microscopy. Through the experimental results obtained, it can say that the chloride has a detrimental

effect on the brass surface which makes the medium very corrosive, that favorie the formation of a

corrosion product layer on the electrode surface. This was explained by the dezincification of tested brass

which illustrated in the images taken by the scanning electron microscope.

The brass alloys have been most important materials in industry, which are used as a pipe material

in condensers and as a heat exchanger in cooling systems. They have valuable physical, mechanical

properties and good electrically and thermally conductive. However, copper has low corrosion resistance,

particularly in the presence of chloride anion [1]. Therefore protection of copper and its alloys from

corrosion is economically important. In the literature, these type alloys have been usually studied in

environments containing NaCl (3.5%) and HCl (3.5%). There are many kind of inhibitors help to slow

down corrosion [2]. The corrosion effective of an organic materials as inhibitor depends on its structure

and the stability of the chelate formed on the metal surface [3]. Especially, nitrogen compounds such as

imidazoles are known as corrosion inhibitors effective on copper and brass surfaces. Benzimidazole and

its derivatives are also widely used on copper and zinc surfaces [4].

In this study, bis-benzimidazole was examined as inhibitor for the brass surface in the NaCl and

HCl media. The synthesis of bis-benzimidazole was carried out by using oxamide and o-

Phenylenediamine. The corrosion performance of brass alloy was studied using Electrochemical

Impedance Spectroscopy in both solutions of 0.5 M NaCl and 0.5 M HCl. Inhibitor efficiencies of bis-

benzimidazole are found as 70% and 49% for brass surface in NaCl and HCl, respectively.

Consequently,bis-benzimidazole provides a cuprous complex on the metal surface which prevents further

copper dissolution.

Key Words: Corrosion, inhibitor, 1% NaCl, 3% HCl, bis- benzimidazole.

Mild Steel(MS) is used in many machines and equipment in the industry. The addition of certain

metals (Ni, Mo, etc.) to the MS and coating with a protective film on the surface causes the corrosion rate

to slow down in aggressive environment[1, 2]. However, the corrosion in the hydrochloric acid

environment is still a major problem. Organic compounds are used as corrosion inhibitors to reduce

corrosion on metal surfaces, particularly in acidic media[3]. The corrosion inhibitor properties of aromatic

ring compounds with electronegative heteroatoms such as S, N, O, P in the structure investigated and

effective results have been obtained[4].

Fig.1 X-Ray Structure of water-soluble Schiff base.

For this, the water-soluble Schiff base (WSS) shown in Fig.1 was synthesized by condensation

reaction of 2,5-diaminobenzene sulphonic acid and salicylaldehyde. The corrosion inhibition effect of

WSS on MS was investigated in 1 M HCl solution. The corrosion inhibition effect was studied by using

cathodic and anodic polarization curve and electrochemical ımpedance spectrometry (EIS), linear

polarization resistance (LPR). scanning electron microscopy (SEM), energy dispersive X-Ray

spectroscopy (EDX) techniques were utilized for characterization of surface morphology.

Biofilm is an essential part of the process of degradation and perforation of pipelines and walls of

reservoirs, pipes clogged with bacterial corrosion products [1-2]. In this study, microbiologically

influenced corrosion (MIC) is a form of electrochemical corrosion that can be observed in many

environments, it will be to identify these bacteria to understand their mode of action. In the case of

corrosion of drinking water pipes, borehole pumping probes in center of Morocco in Khénifra-Béni

Mellal region at the irrigated perimeter [1]. In order to understand biocorrosion, the abundance and

activities of bacteria in biofilms, two hundred (200) samples were collected for four (4) seasonal

campaigns at the rate of forty tree (43) samples per season in irrigated zone, between March 2017 to May

2018. Those samples were analyzed to identify P. aeruginosa isolates, according to the ISO 6887- 2

standard method [3]. The study revealed a total of (n=85/139) isolated strains has identified as P.

aeruginosa representing 61.15 % of prevalence among Pseudomonas spp. While the high level of mean

densities varied in S21 from a minimum of 3,20E+01 CFU/mL to a maximum of 4,75E+04 CFU/mL, in

S29 from a minimum of 1,70E+03 CFU/mL to a maximum of 7,99E+03 CFU/mL, S40 from a minimum

of 1,02E+03 CFU/mL to a maximum of 8,50E+03 CFU/mL, and S26 from a minimum of 0,00E+00

CFU/mL to a maximum of 6,80E+03 CFU/mL. The generation of these concentration of biofilm is

distributed on all study area. Therefore, these bacteria cause pitting corrosion on the steel surface through

biofilm formation and further colonization P. aeruginosa, which could cause a health risk for the

sedentary population. The urgent attention will be given to the maintenance of wells canalisations before

consumption inadequate waters, to prevent their possible alteration or reduce the risk of biocorrosion.

Key words: Biocorrosion, P. aeruginosa biofilm, pipelines.

Among the other protective coatings, zinc and zinc alloys (ZnFe, ZnCo, ZnNi) are widely used on

steel. Zinc alloys improved corrosion resistance compared to pure zinc in the protection of ferrous-based

metals. This is easily achieved by alloying Zn with more noble metals such as Fe, Ni and Co. The

development of conducting polymers as coating materials for corrosion protection of metals/alloys has

become a significant new research field. Among widely used conducting polymers for this purpose are

polyaniline and its derivatives as well as polypyrrole [1-3].

In this study, zinc–nickel (ZnNi) particles were electrochemically deposited on carbon steel (CS)

electrode applying current of 1 mA with chronopotentiometry technique. Homogenous and adherent

poly(N-methylaniline) film was synthesized with cyclic voltammetry technique from 0.02 M N-

methylaniline containing 0.20 M sodium oxalate solution on CS/ZnNi electrode. The characterization of

ZnNi deposited carbon steel electrode with and without poly(N-methylaniline) film have been

investigated by using AC impedance spectroscopy technique, linear sweep voltametry technique, anodic

polarization curves, corrosion potential-time curves and scanning electron microscopy. The results

showed that polymer film exhibited significant barrier property against the attack of corrosive agents.

Key Words: Poly(N-methylaniline), Corrosion, ZnNi, Electrochemical synthesis.

Microbiologically influenced corrosion (MIC) is a form of corrosion that can be observed in

environment. It is initiated, facilitated or accelerated by the presence of bacteria and mostly appears in the

form of localized pits and crevices on metal surfaces. However, the ability of Clostridium sulfite reducers

to colonize a new facility causing an increase in corrosion rate was indicated in this study, which took

place in central Morocco in the region Khenifra-Béni Mellal at the irrigated perimeter, we focused on

corrosion by Clostridium perfringens, which is manifested between these anaerobic bacteria capable of

transforming sulphates and sulphites to sulphides, and the materials on which they are attached [1-3]. The

presence of C.perfringens leads to an acceleration of corrosion by chemical processes in corroded places

(sewage systems, drilling pump...). In order to understand biocorrosion, the abundance and activities of c.

Perfringens, two hundred (200) samples were collected for four (4) seasonal campaigns (two rainy and

two dry) at the rate of forty tree (43) samples per season in irrigated zone, between March 2017 to May

2018. The TSC Agar method was used for identifying C. Perfringens strains, according to the ISO 64611-

1 standard method [2]. This study revealed a total of (n=145/200) isolated strains has identified as C.

Perfringens representing 72.5 % of prevalence. While the high level of mean densities varied in S2 from a

minimum of 5,00E+00 CFU/mL to a maximum of 3,00E+02 CFU/mL, in S24 from a minimum of

3,00E+01 CFU/mL to a maximum of 1,00E+02 CFU/mL, S41 from a minimum of 8,00E+00 CFU/mL to

a maximum of 2,50E+02 CFU/mL, and S12 from a minimum of 4,00E+00 CFU/mL to a maximum of

2,50E+02CFU/ml. It is clear that future work will have to be devoted to the treatment of drinking water

against bacterial contamination and also against corrosion. It is imperative to prevent their possible

alteration or reduce the risk of biocorrosion.

Key words: Biocorrosion, C. Perfringens, microbiologically influenced corrosion (MIC).

POLİPİROLÜN NaCl ve H2SO4 ORTAMINDA ÇELİĞİN KOROZYONUNU

ÖNLEMEDEKİ ETKİLERİNİN KARŞILAŞTIRMALI İNCELENMESİ

E. ATEŞ GÜVEL1, N. KIZILCAN1, B. USTAMEHMETOĞLU*1, E. SEZER1 1İstanbul Teknik Üniversitesi, Kimya Bölümü, Maslak / İSTANBUL / TÜRKİYE

İletken polimer çevre açısından toksik olmamaları sayesinde, korozyon önlemede kromata dayalı

kaplamalara alternatif olarak yaygın biçimde incelenmektedir [1-2].

Bu çalışmada polipirol (PPy) değişik sayıda döngüler (16, 32, 64 döngü) uygulanarak paslanmaz

çelik (SS) yüzeyine potansiyodinamik yöntemle kaplanmış ve korozyonu önlemedeki etkileri %3,5 NaCl

ve 0,5 M H2SO4 ortamlarında karşılaştırmalı olarak incelenmiş ve en etkili kaplama koşulları

belirlenmiştir. Bu amaçla SS elektrodun ve değişik kalınlıklarda PPy ile kaplanan elektrotların

polarizasyon ölçümleri ve elektrokimyasal empedans spektroskopisi ölçümleri (EIS) gerçekleştirilmiştir

(Şekil 1). Bu ölçümlerden zamana bağlı olarak elde edilen korozyon akım(icor) ve potansiyelleri (Ecor),

polarizasyon direnci (Rp), kırılma noktası frekansı(fb), çift tabaka kapasitansı(Cdl) değerleri

karşılaştırılmış ve optimum koşul belirlenmiştir. Sonuçlar, 0,5 M H2SO4 ortamında 64 döngü ile

kaplandığında, PPy’ün korozyon önlemede diğer kaplamalara göre daha etkili olduğunu göstermektedir.

THE SYNTHESIS OF SILICON CARBIDE FILM ON ALUMINA CERAMICS

Yusuf NUR*1, E. Gizem BAYOL1 1Mustafa Kemal University, Chemistry Department, Antakya / HATAY / TURKEY

Polymeric precursors being an important class of polymers are the interface between polymers and

ceramics. They can be easily converted to ceramic materials upon moderate heating. The most important

properties of these polymers are to form tough, hard-wearing ceramic materials with high thermal

stabilities. Poly(methyl silyne) (PMSi) [1] and polyhydridocarbyne (PHC) [2] are the most famous pre-

ceramic polymers. PMSi can be easily converted to silicon carbide (SiC) [1] ceramics on pyrolysis, while

PHC forms diamond and diamond-like carbon (DLC). Poly(silyne-co hydridocarbyne) (PSC) simply

forms silicon carbide without requiring the addition of more carbon species and a catalyst since it already

contains silicon and organic carbon on its backbone (Scheme 1). Due to solubility of PSC in common

organic solvents, it can be easily coated to alumina ceramics in desired thickness. Then, this PSC film

formed SiC film on an alumina ceramics under inert atmosphere upon moderate heating. This ceramic

film was characterized via SEM and Raman spectroscopy.

Figüre 1: Schematic representation of the electrochemical synthesis of PSC.

UV/Vis spectroscopy, 1H-NMR and GPC analyses were proved the structure of PSC as shown in

Fig. 1. Heat treatment of PSC produces a hard crystalline substance in high yield; typically in the range of

30-50%, depending on pyrolysis temperature. Pyrolysis at 1000oC (SiC1) and 750oC (SiC2), respectively,

resulted in about 35% yield ceramic, while the material at 500oC (SiC3) under Ar atmosphere was

obtained in 48% yield. According to The wide angle X-ray powder diffraction (XRD) analysis, while

SiC3 was X-ray amorphous, the samples produced at higher temperature, SiC1 and SiC2, were

crystalline, and their reflections were consistent with the mixture of 3H-SiC, 4H-SiC, 5H-, 6H- and 24R-

SiC. These crystalline samples are mostly composed of 5H- and 6H SiC, which results are consistent with

ICDD, the Raman analyses.

Key Words: Electropolymerization, pre-ceramic polymer, silicon carbide, ceramic.
