Protective wear coating and component with a protective wear coating

摘要

The invention relates to a protective wear coating, in particular an erosion protection coating, for a power component as claimed.According to the invention, the protective wear coating one or more, which is applied on the surface to be coated, each sheath (15, 16), each of the each sheath (15, 16) has at least four different layers. A first, the surface to be coated layer which faces (17) of each more layers layer system is made of a to the composition of the surface of the formed metal material that is adapted to be coated. A to the first layer applied to the second layer (18) of each more layers layer system is made of a to the composition of the component surface is adapted to be coated metal alloy material. On the second layer is applied a third layer (19) of each more layers layer system is made of a graded metal - ceramic - material and a third layer applied to the fourth layer (20) of each more layers layer system is formed from a nanostructured ceramic material.
