A method for applying a coatingto a surfaceof a mullite materialis specified, which comprises pretreating the surfaceof the mullite materialby means of a plasma-chemical process in which molecular hydrogen is excited in such a way that plasma-activated hydrogen is produced S, and applying an aluminum oxide-containing layerby means of a PVD process to the pretreated surfaceof the mullite materialS. Furthermore, a mullite materialwith a coating and a gas turbine component with such a mullite materialare specified.

Method for applying a coating to a surface of a mullite material, mullite material having a coating, and gas turbine component

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

The use of especially an aluminum alloy on a metal substrate in a PVD-AlTiN coating results in good corrosion and erosion protection.
