Abstract

Provided is a coating system for a substrate, the system including a first, second and third layer. In the system, the first layer is designed as an adhesion promoter layer, the second layer is a ductile metal layer with a columnar structure and the uppermost, third layer is a ceramic oxide layer with a high hardness value. The substrate is ideally an element of a compressor component of a stationary gas turbine. Also disclosed is a method for producing the coating system.
