Abstract: REPAIR OF COATED TURBINE VANES INSTALLED IN MODULEA method of repairing a damaged coated vane from a turbine module without removing the vane from the module is taught. The method includes locally removing the coating in the vicinity of the damage as well as any underlying damage in the superalloy substrate. A diffusible coating precursor is then applied to the damage site. A heat treating fixture is then mounted on the vane and repair site is heated to up to 2000°F in an inert environment to interdiffuse the coating precursor and the substrate. After the diffusion anneal, the vane is cleaned and the module is returned to service.Fig. I

Abstract: A method for coating a metal component of a gas turbine engine, the method comprising forming a cathode ingot for a cathodic arc deposition process, and performing a cathodic arc deposition process on the metal component with the cathode ingot to form a bond coat, where the formed cathode ingot comprises an MCrAlY alloy base portion and a platinum-modified aluminide outer coating disposed over the base portion.
