Abstract:
1. A wear-resistant coating, in particular an erosion-resistant coating applied to a surface of a component that is exposed to fluid loads, in particular a gas turbine component whose surface is to be protected, wherein the wear-resistant coating is made of one or more multilayer systems applied repeatedly to the surface to be coated, wherein each of the multilayer systems has at least four different layers, wherein a first layer facing the surface that is to be coated of each multilayer system is made of a metallic material adapted to a composition of the component surface that is to be coated, wherein a second layer applied to the first layer of each multilayer system is made of a metal alloy material that is adapted to the composition of the component surface to be coated, wherein a third layer applied to the second layer of each multilayer system is made of a gradated metal-ceramic material and a fourth layer applied to the third layer of each multilayer system is made of a nanostructured ceramic material.
