Sliding component that is coated with a metal-containing carbon layer to improve the wear and friction behavior by tribological applications in lubrication conditions

摘要

Reduction of friction and wear are improved compared with the prior art to be achieved, the present invention is used in combination with zinc-containing lubricants and / or molybdenum-containing, and DLC containing coating diamond-like carbon (DLC) or relates to a coating for a sliding element which allows. Me-C / a) -C coating system according to the present invention: it contains at least a metal-containing carbon layer of X-type, and its elemental composition _is represented by _{(Me a} C _1-a) as a _{1-b X} b obtained, wherein, 0.3 ≦ a ≦ 0.6,0 a b ≦ 0.3, Me is a combination of different metals or metal, X is an element different from C and, unlike Me or is, X is a mixture containing no C, and is a mixture of different elements and Me. Is Me, preferably obtained, the X, may preferably be a mixture of silicon and hydrogen (H) or hydrogen (Si + H) of chromium (Cr) or molybdenum is (Mo).
