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 with an additional layer with material different from the DLC coating material, thereby closing the pin holes of the DLC layer.
