Increases in automated production and assembly makes

solid film lubricants ever more important. They make it

possible to provide many structural components with

dry, efficient lubrication and, compared with conventio-

nal lubricants, permit designs to be simpler. They

improve the running-in of highly-stressed machinery

components, simplify installation processes and,

in many instances, guarantee maintenance-free

lifetime lubrication.

Solid film lubricants manufactured by FUCHS LUBRITECH

are "state-of-the-art" and meet the increasing technical

demands made by diverse sectors such as industrial and

plant technology, metal-processing industry, machinery

construction and the commodity goods and automotive

industries.

In addition to their outstanding technical properties, the

solid film lubricants made by FUCHS LUBRITECH also

comply with the ever-increasing demands to address

environmental issues.

In many instances, if it's a question of dry film

lubrication, solid film lubricants are the optimum

choice. Solid lubricant coating has proved its

worth many times over and today provides a reli-

able and indispensable design element.

STRUCTURE AND FUNCTIONOF SOLID FILM LUBRICANTS

The fundamental difference compared with normal industrial varnishes

is that they contain solid lubricants instead of colour pigments.

Apart from the main components – binders, solid lubricants and

solvents – solid film lubricants may also contain functional additives

such as corrosion inhibitors or UV active components.

STRIBECK DIAGRAM: MODEL OF THE FRICTION AREASDURING FLUID LUBRICATION

Initial smoothing of the surface of the solid film

lubricant takes place as a result of the relative

movement of the opposing surfaces.

A partial discharge of material from the solid film

lubricant layer creates a "transfer" film on the

opposite surface. The build-up of lubricating film

between the two surfaces leads to a reduction in

the coefficient of friction.

The solid film lubricant provides the dual advantage

of dry and clean lubrication and in many instances

can replace the use of greases and fluid lubricants,

particularly where slow sliding movements are

involved. In addition solid film lubricants can be

used in combination with fluid or pastes. Solid film

lubricants enhance the lubrication of components

in the boundary friction region, when there is

no hydrodynamic lubrication and direct contact

between the surfaces occurs.

After drying and curing, solid film lubricants form a

strong dry coating several microns thick, by adhe-

ring firmly to the substrate. The film reduces both

wear and friction as well as acting as a parting

agent and provides lubrication between the oppo-

sing surfaces.

PRE-TREATMENTSurface preparation of the parts to be coated plays an

important role during solid film lubricant coating.

Good adhesion and therefore long lifetime can only be

achieved with a pre-treatment which is customised for

the particular part and solid film lubricant. Thorough

removal of all grease residues, dust, dirt, rust and scale is

a fundamental part of the pre-treatment of the work

piece surface.

PLASTIC PARTS:

De-greasing of plastics and elastomers can be achieved

with aqueous cleaners or solvents. When using solvents,

however, attention should be paid to compatibility with

the plastics to be cleaned.

The adhesion of the solid film lubricants can be impro-

ved by roughing the surface, for example. Suitable

methods are grinding or blasting with CO2 or sand.

Deformation of the parts or surface damage must be

avoided. Alternatively, physical methods such as plasma

activation, corona or flame treatment can be used for

the pre-treatment of plastics.

METAL PARTS:

De-greasing can usually be done by using organic

solvents, such as, for example, hydrocarbon, acetone etc.

A more environmentally and user-friendly result can be

achieved by using alkaline or neutral aqueous cleaners.

The effectiveness of the cleaners can usually be inten-

sified when combined with ultrasound or heat.

Rust and scale can be removed mechanically or chemi-

cally. Grinding or blasting are suitable mechanical

pre-treatment methods. Rust and scale can be removed

chemically through pickling in acids or lyes.

Phosphatising can give significantly improved adhesion

of the solid film lubricant onto the metal surface.

Phosphating improves both the mechanical properties

and corrosion protection of the parts to be coated.

Normally, zinc or manganese phosphating is used.

APPLICATIONDecisive for the application of the solid film lubricant are

primarily the geometric shape of the parts and the tech-

nical application properties of the selected coating.

Application is principally undertaken using traditional

processes found in coating technology, such as, dipping,

tumbling, dip-centrifuging and spraying.

SPRAY-COATING

For most products it has been shown that the "non vola-

tile part" of the solid film lubricant should be set at

about 26-30% for spray application. The non-volatile

part corresponds to the dry residue, i.e. the dry lubricant

coating after the solvent has evaporated.

Any standard spray gun may be used. HVLP spray guns,

with a circular/spread jet setting and a nozzle diameter

of 0.5-0.8 mm, have proved to be particularly suitable.

The specific design of the HVLP spray technology allows

varnish utilisation of up to 60%.

In many usages pre-heating of the parts to be coated to

60-80°C is an advantage. This also allows the application

of layers with a thickness greater than 20μm

without intermediate ventilation. Spray-coating usually

achieves layer thicknesses of 10-30 μm.

DIP-CENTRIFUGING

During centrifuge coating, it is recommended to set the

non-volatile part to 22-28%, in order to achieve an

optimum coating result. Here, too, it can be an advan-

tage to pre-heat the parts to be coated to 80-85ºC.

Higher temperatures lead to partial accumulations of

varnish and rough surfaces, lower temperatures only

give rise to very thin layers. The ideal degree of filling of

the centrifuge depends on the plant and usually has to

be determined empirically (guideline: 60-70%). Using

this method of application varnish utilisation can

amount to up to 90%.

It is, however, difficult to achieve homogenous layers

over 10μm thick. With dip-centrifuging there is the dan-

ger that the parts will stick together (particularly parts

with flat surfaces). The parts should, therefore, be

moved continuously during dipping and also when

drying or curing afterwards.

DRUM COATING

Coating in drums is particularly suitable for bulk goods,

which have simple shapes (e.g. washers, bolts, pins,

O-rings). An advantage of this process is the surface

smoothing that occurs due to the friction between the

coated parts in the drum and so homogenous layer

surfaces can be achieved. By combining it with a spray

coating in so-called "spraying drums" the thickness of

product deposited can be controlled precisely, thereby

giving an improved coating.

HARDENINGAir-drying solid film lubricants are dried at room tem-

perature before being subjected to frictional load, while

heat-cured solid film lubricants are cured after coating.

Normal curing temperatures are in the region of approx.

100-200ºC. More detailed information about the solid

film lubricants made by FUCHS LUBRITECH can be

obtained from the relevant product information sheets.

QUALITY CONTROLThe general criteria used for the quality control of solid

film lubricant layers are the surface finish, the coating

thickness and adhesion to the surface of the component.

Transparent solid film lubricants usually contain

a special UV indicator which can be made visible with a

UV lamp and allows "Yes/No" control.

Further control parameters are determined by the shape

of the component and the requirements of the coating

applied. Quality control statistical analysis using

appropriate test rigs is rarely required.

The selection of a suitable solid film lubricant requires a

high degree of professional competence and is mainly

determined by these factors: type of component,

purpose of the coating, surrounding conditions and

quality management requirements.

Solid film lubricants manufactured by FUCHS LUBRITECH

have proved themselves in many fields and represent the

optimum solution for dry and clean lubrication. Thus, for

example, they can provide installation-compatible

lubrication for screw connections, fitted parts and

O-rings, help to minimise wear on gear components

and provide lifetime lubrication for components

essential to safety.

The assessment as to whether a solid film lubricant is suit-

able for providing lifetime lubrication for a component

must usually be proved through trials on suitable test

rigs. Generally solid film lubricants have a limited service

life, which will be indicated in the trial by an increase in

the coefficient of friction and the appearance of wear

phenomena. Thus, it should be noted that load and

sliding speed of the component can have a great

influence on the performance of the solid film lubricant.
