Abstract

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.
