TRIBOLOGY COMBINED WITH CORROSION RESISTANCE: A NEW FAMILY OF PVD-AND PACVD COATINGS

摘要

The present invention relates to a coating system on a substrate with improved protection against wear as well as corrosion. According to the invention the substrate is coated with a diamond like carbon (DLC) layer. This DLC layer is coated an additional layer with material different from the DLC coating material, thereby closing the pin holes of the DLC layer.
