Tribocorrosion Wear Evaluation of Protective Coating
The tribocorrosion process of the DLC coatings on different types of steel substrates is simulated using the Nanovea Tribometer. In this study, we would like to showcase that Nanovea Tribometer equipped with the Tribocorrosion Module is an ideal tool for evaluating the performance of protective coatings used in wear and corrosion environment.
Pitting Corrosion density, area, volume, size and shape
In this application the Nanovea ST400 Profilometer is used to measure the surface of a corrosion pitted stainless steel coupon. The area measured was selected at random, and assumed large enough in that it could be extrapolated to make assumptions
about a much larger surface. Density, area, volume, size and shape will be used here to quantify the level of corrosion.
Here are examples of materials we tested this month:
Mechanical:
• Nanoindentation of wire cross sections
• Nanoindentation of Y2O3 thin films
• Nanoscratch of thin polymer films
• Nanoscratch of catheters
• Microindentation of oil-well cement
3D Non-Contact Profilometry:
• Roughness of catheters
• Finish of processed leather
• Topography of thin film particle contaminants
• Coplanarity of ball grid arrays
• Step height of microchannels
• Stribeck Curve evaluation of various lubrication

Transparent Film on Transparent Substrate Measurement
The Nanovea PS50 Profilometer is used for roughness measurement, step height thickness and optical thickness of a thin transparent film on a transparent glass substrate. Step height will be obtained by measuring an area of the film and an area where the substrate is exposed for relative height difference, while optical thickness will be measured by using the Profilometer capability of measuring through the transparent film and detecting a reflecting both from the top surface of the film and the substrate simultaneously.
