The present invention relates to zinc containing lubricants in a manner that improves the reduction of wear and friction as compared to the state in which DLC and / or technology comprising coatings associated with diamond-like carbon (DLC) or molybdenum are achieved. It relates to a coating for sliding parts that can be used. The coating system according to the invention is a carbon layer of type Me-C / aC: X comprising at least a metal, the element composition being 0.3 ≦ a ≦ 0.6 and 0 <b ≦ 0.3. Or (Me a C 1-a ) 1-b X b , where M is a metal or a combination of other metals, X is a component different from M and a component different from C, or X is a component different from Me It is a mixture of and does not contain C. Me may preferably be chromium (Cr) or molybdenum (Mo), X may preferably be hydrogen (H) or a mixture of silicon and hydrogen (Si + H). |
