SLIDING ELEMENT, IN PARTICULAR PISTON RING, HAVING A COATING AND PROCESS FOR PRODUCING A SLIDING ELEMENT

摘要

A sliding element, in particular a piston ring, has, on at least one running surface from the inside outwards, a coating with a metal-containing bonding layer and a DLC layer of the type ta-C with a thickness of at least 10 µm. In a process for producing a sliding element, in particular a piston ring, coating is effected with a metal-containing bonding layer and a DLC layer of the type ta-C in a thickness of at least 10 µm.
