ANTI-WEAR COATING AND COMPONENT COMPRISING AN ANTI-WEAR COATING

摘要

The invention relates to an anti-wear coating, in particular an anti-erosion coating, which is applied to the surface of a component to be protected that is used in flow technology, in particular a gas turbine component. According to the invention, the anti-wear coating is formed by one or several multi-layer system(s) applied in succession to the surface to be coated and the or each multi-layer system comprises at least one relatively soft metallic layer and at least one relatively hard ceramic layer. According to the invention, all layers of the or each multi-layer system are chromium-based and a diffusion barrier layer with a mono-nanostructure is applied to the multi-layer system or systems.
