Abstract

The invention relates to an anti-wear coating, specifically for components which are subject to erosion under mechanical loading, in particular for gas turbine components, said coating comprising at least two different individual layers which preferably alternate with one another multiply and are applied to a surface of a component which is to be coated. The individual layers comprise a ceramic main layer (45, 46, 47, 48) and a quasi-ductile, non-metallic intermediate layer (41, 42, 43, 44).
