摘要

A method for coating a surface of a component formed from aluminum or an alloy thereof includes the step (204) of cold gas-dynamic spraying a powder material on the component surface to form a coating, the powder material comprising at least one alloy from the group consisting of titanium, a titanium alloy, nickel, a nickel alloy, iron, an iron alloy, aluminum, an aluminum alloy, copper, a copper alloy, cobalt, and a cobalt alloy. In one embodiment, the method further includes the step (210) of heat treating the turbine component after the cold gas-dynamic spraying.
