® Taperader Micro Grinding Micro Calotest Micro Tribology Thin Coating Thickness Innowep GmbH Haugerring 6, Würzburg, Germany 97070

Basic Functions Thin films and coatings with a few nm to µm thickness are often applied on many products for the optimization of their mechanical properties and tribological performance. There- fore, an accurate measurement with high resolution is essential for R&D, quality assurance and process optimization • Mobile design for many industrial applications. Thickness measurement is • Fast and easy measurement typically done with a combination of indentation and scratch tests, and they are mostly for thicker coatings in macrome- • Real-time in-situ measurement • Analysis of surface/coatings abrasion...

Test Principle A constant load is applied on the sample surface while a running tape grinds the surface for a duration between 60 to 240 seconds. The generated abrasion depth (difference between h1 and h2) is measured by a built-in optical sensor and is displayed on a LCD touchscreen. Test Results Comparison of abrasion resistance behavior of different polymers Along the abrasion time (s), coatings with higher abrasion resistance show a smaller abrasion depth Innowep GmbH Haugerring 6, Würzburg, DE 97070 T 0049 931 322 980 F 0049 931 322 9812 [email protected] www.innowep.com
