For highly loaded components the use of environmentally friendly PVD technology is an absolute requirement. With the extreme wear-reducing properties of PVD coatings component lifetimes can be dramatically increased, or by use of a designin concept the overall component system cost can be reduced. Especially for tribologically loaded systems, the application of coatings with low friction coefficients, such as amorphous carbon layers, can open new perspectives and applications for your products. When moving parts are subjected to large frictional forces in applications that require high wear resistance, then low-friction tribological systems are the solution.

Tribological coatings support heavily loaded tooth contact surfaces and increase the maximum performance of the gear. Additionally, coatings tend to have a polishing effect on the counter surface, thereby reducing its roughness and the related contact pressures. Also, the relatively thin coating thickness of 1 to 4 μm is typically within the gear wheel tolerance specifications, and the option of low-temperature processing allows tempered low-alloy steels to be coated without loss of hardness.
