摘要： A sliding element, such as a piston ring, for use in diesel or highly supercharged spark-ignition engines with iron-based mating running elements is provided. The sliding element includes a base material made of cast iron or steel and a coating. The coating includes a CrN layer, an Me(CxNy) layer, and a DLC layer extending from the inside to the outer side respectively. The DLC layer consists of a metal-containing substructure layer and a metal-free DLC top layer. The Me(CxNy) layer is crystalline and Me is tungsten (W), chromium (Cr), or Silicon (Si). The hardness of the metal-free DLC top layer is harder than the metal-containing substructure layer.

摘要： A method for producing a dispersion-hardened object which contains carbide nanoparticles comprises producing an object by means of a thermal spraying method, wherein downstream of the combustion chamber, the gas flow is supplied by means of a carrier gas with at least one precursor which reacts in the gas flow to form a carbide, or carbide nanoparticles are supplied via an external nanoparticle generator which is subject to a thermal load. It allows the production of a dispersion-hardened object such as, for example, a component for an internal combustion engine, for example a piston ring. The method is carried out by means of a thermal spraying device which, downstream of the combustion chamber, besides at least one line for supplying a thermal spray powder, further comprises at least one line for supplying a precursor by means of a carrier gas.
