Plastic component having erosion layer for applications with erosive stress

摘要

The present invention relates to a component, which is exposed to air - or gas flows and predominantly is formed of a plastics material, so that the plastic material at least in part in the area of the surface exposed to the flow of the component (1) is present, in which the plastic material a protection from erosion on the surface, and wherein the erosion protection, a multilayer coating system (2, 3; 2, 7, 8, 3) with at least one or more sequences of at least one layer of a metal (2) and at least one layer of a ceramic material (3) or from at least two differently hard ceramic layers (2, 3) comprises, as well as a process for the production of a component exposed to air - or gas flows with the following steps:a) providing a component (1) consisting predominantly of plastic material with at least a part of a surface, which is formed by the plastic and is exposed to air - or gas flows;b) applying a more layers layer system (2, 3; 2, 7, 8, 3) of at least one or more sequences of at least one layer of a metal and at least one layer of a ceramic material or from at least two differently hard ceramic layers on at least the part of the surface is formed by the plastic and is exposed to air - or gas flows.
