SLIDING COMPONENT COATED WITH METAL-COMPRISING CARBON LAYER FOR IMPROVING WEAR AND FRICTION BEHAVIOR BY TRIBOLOGICAL APPLICATIONS UNDER LUBRICATED CONDITIONS
摘要
The present invention relates to a coating for sliding parts that allows using diamond like carbon (DLC) or DLC-comprising coatings in combination with Molybdenum- and/or Zinc-comprising lubricants in such a manner that enhanced reduction of wear and friction in comparison to the state of the art is attained. The coating system according to the present invention comprises at least a metal-comprising carbon layer of the type Me-C/a)-C:X, whose element composition can be expressed as (MeaC1-a)1-bXb with 0.3 =a =0.6 and 0 < b =0.3, where Me is a metal or a combination of different metals and X is an element different from Me and different from C or X is a mixture of elements different from Me and which doesn't contain C. Me can be preferably Chromium (Cr) or Molybdenum (Mo) and X can be preferably hydrogen (H) or a mixture of silicon and hydrogen (Si + H).
