摘要：
Methods are provided for forming a coating system (102) on a gas turbine component (100). In one embodiment, and by way of example only, the method (200) includes cold spraying (204) a material onto the component surface to form an overlay coating (104), the material comprising MCrAlY, wherein M comprises a constituent selected from the group consisting of Ni, Co, or Fe, or combinations of Ni, Co, and Fe. Then, the overlay coating (104) is heat treated (206). The overlay coating (104) is then shot peened and vibro polished (208). A thermal barrier coating (106) is then applied onto the overlay coating (104) to form the coating system (102) via air plasma spaying or electron beam physical vapor deposition technique.
