VDI 3198 Coating of Cold Forging Tools - Standard Test for CVD and PVD Processes

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of VDI 3198 testing. Single- or multi-layer coated compounds are strong alternatives to conventional bulk materials that normally show limited surface performance.

Today, advanced and complex techniques are encouraged in film production devices, leading to the development of a wide variety of different coating types. In this way, soft, hard or super-hard films can be produced in single or multi-layer textures, thus serving demanding applications requiring improved surface handling.

Given the increasing industrial and manufacturing demands, a well-organized competition of characterization processes is required for such coatings. This article describes the methodology and typical results of a fast, reliable and cost-effective quality test based on Rockwell C indentation on planar surfaces of coated compounds.

This destructive test can rigorously exhibit the two hallmarks of the coated compound, namely interfacial adhesion as well as film brittleness and cohesion. The stress-strain field that occurs during the notching and loosening stages, respectively, must be carefully considered to obtain reliable conclusions regarding the quality of the pavement backing system.
