SLIDING ELEMENT, IN PARTICULAR PISTON RING, HAVING RESISTANT COATING

摘要

The present application relates to a sliding element, in particular a piston ring, having a coating (10) on a substrate (12), which forms at least one sliding surface of the sliding element. The coating (10) has, from the inside outwards, a carbide or nitride layer (16), then a carbide-containing (preferably PVD-) TLC layer (17), then a metal-free PVD-TLC layer (22) and then a metal-free PACVD-TLC layer (18).
