Abstract

For producing a component, especially a gas turbine component, coated with a wear-protection, corrosion-protection or erosion-protection coating, a method includes the following steps: providing a component (10) to be coated on a component surface (13); at least partially coating the component (11) on its component surface with an at least two-layered protective coating (14), which includes at least one relatively soft layer (15) and at least one relatively hard layer (16); and then surface densifying the at least partially coated component on its coated component surface by ball blasting or shot peening.
