  • Sliding Element, in Particular Piston Ring, Method for Manufacturing a Sliding Element, Sliding System and Coating for a Sliding Element
    Publication number: 20090001669
    Abstract: A sliding element comprises at least one surface for sliding contact with a running face, wherein a wear layer and a run-in layer made from carbon are applied to the surface, and is characterized in that the run-in layer comprises hydrogen and nanocrystalline carbide phases. In a method for manufacturing a sliding element, the run-in layer is applied by means of a PVD process. A sliding system has an above-described sliding element and a body having a running face. A coating for a sliding element comprises a wear layer which can be applied to the upper side of the sliding element, and a run-in layer which is configured as a carbon layer, and is characterized in that the run-in layer comprises hydrogen and nanocrystalline carbide phases.
