  • Patent number: 9528180
    Abstract: 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).

  • Patent number: 9121092
    Abstract: The present invention relates to a coating system on a substrate with improved protection against wear as well as corrosion. According to the invention the substrate is coated with a diamond like carbon (DLC) layer. This DLC layer is coated with an additional layer with material different from the DLC coating material, thereby closing the pin holes of the DLC layer.
