www.nlr.nlNLR - Dedicated to innovation in aerospace
The National Aerospace Laboratory NLR offers
material and failure analysis for the aerospace and
high tech industry.
From a multi-disciplinary approach NLR delivers
the essential feedback to design, manufacturing,
maintenance/repair and safe operation.
The modern material facilities and extensive
experience provide NLR the capabilities to ensure
proper material solutions for our national and
international customers.
The facility includes:• Fully equipped material testing and investigation laboratory• Metallographic imaging equipment for microstructural examination and material
characterization• Scanning electron microscope with EDX/WDX and EBSD• Portable microscope and replication kit for field investigations• Environmental test facility• High temperature test facility
“WHERE QUESTIONS ABOUT MATERIALS ARE ANSWERED”
Material and failure analysis
Salt spray test for the replacement of chroming plating as applied on landing gears (left side before the test, right side after 192 test hours)
Test method for mechanical hydrogen embrittlement evaluation of plating/coating processes and service environments
Determination of the residal stress in material after an applied process
BEFORE AFTER
Different thermal expansion coefficent
Fact: strange drive shaft geometry
root cause analysis of F16 crash
Remedy:Worldwide replacement of
the steel bolts by nickel bolts
Steel bolts and nickel bracket
bowed out due to overheating
What causes the load cycles?
Is the overheating
of the drive shaftcaused by an oil
fire?

“THE RIGHT PARTNER IN MATERIAL RESEARCH”
The replacement and/or implementation of new materials or coatings are driven by technical performance, costs or environmental requirements. For aerospace applications, these new materials or coatings must be validated on the effectiveness to the service live. NLR is fully equipped to guide you through the entire validation process. An example of this validation is the replacement of chroming plating on landing gears of airplanes.
