Coating Properties

Coatings can improve the application properties of a substrate significantly. For development and application of such coating systems the relevant properties have to be measured in a precise and reproducible manner.

Our main fields of expertise are tribology, contact mechanics and surface acoustic wave spectroscopy with extensive know-how in methodology, application and process development. Our characterization comprises all kinds of coatings with emphasis on PVD coatings and superhard amorphous carbon coatings (ta-C).

Highlight

 

LAwave - Laser acoustic test system

The LAwave measuring system, developed at the Fraunhofer IWS, allows non-destructive characterization of films and material surfaces, for example measurement of Young’s modulus, coating thickness, density, porosity, delamination, and depth of hardening or damage layers.
