D.L.C. tribological coatings.
Diamond Like Carbon coatings.

 

DLC demonstrates a high hardness combined with excellent resistance to abrasive and adhesive wear together with extra low coefficient of friction.

 

This unique combination of properties offers the best solution to protect automotive components, to lower the coefficient of friction and consequently to reduce the CO2 emissions.
Typical applications already mass production:
– Valve actuation
– Fuel system
– Transmission
– Etc.
DLC coatings can be multi-layered using materials such as Cr, CrN, Si, W, WC- C, … and an amorphous carbon top-layer hydrogenated or not.
The choice of the under-layer is based on the application (contact pressure, etc.)
