Here are examples of materials we tested this month:
Mechanical:
• Nanoindentation & scratch of tungsten carbide coatings
• Nanoindentation DMA of fluoropolymer
• Microindentation & scratch of DLC coatings
• Macro scratch firearm parts
3D Non-Contact Profilometry:
• Roughness of precision machined components
• Texture of textile samples
• Coplanarity of ball grid arrays
• Volume loss of dental samples
• Flatness measurement of micro seals
Tribology:
• Wear resistance of hard polymers
• Wear resistance of firearm parts
• High temperature fretting of engine parts
• Stribeck Curve of lubricants
Surface Roughness Statistical Analysis Using 3D Profilometry
In this application the Nanovea ST400 Profilometer is used to measure over 30 coupons with similar surface features with only slight differences. The surfaces were analyzed for parameters such as surface roughness, maximum height, maximum peak height and root mean square. A statistical analysis was then performed using histograms, tables, control charts, box plots and
scatter plots.
