A layer system having a metallic substrate, in particular made of a >=9% by weight chromium steel, in particular with roughness of the substrate <=2 μm and optionally an intervening chromium layer directly on the substrate, in particular made of Cr/CrN, an underlayer or middle layer of AlCr, and an outer layer, in particular outermost layer, of AlCrO, where the AlCr and AlCrO layers in particular are PVD coatings wherein a shark skin effect is achieved with a simple geometric arrangement, and can be used particularly for compressor blades.

Layer system and blade

A coating composition for coating of components of a flow machine, especially a turbomachine such as a gas turbine with compressor, or of a compressor, which are exposed to the fluid stream of the flow machine or of the compressor, wherein the coating composition includes anticorrosion pigments, wherein the coating composition includes hard material particles, and wherein the coating composition is an RT-curing, UV-curing and/or thermally curing coating composition. A component of a flow machine or of a compressor has the coating composition. A method of maintaining a flow machine or a compressor uses the coating composition.

Coating composition for surface repair of turbomachine components and compressor components

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.
