    摘要: A method of repairing a component of a gas turbine engine that includes a metallic substrate (24), an existing coating, and a diffusion layer formed in the metallic substrate adjacent to the coating. The method includes removing at least a portion of the existing aluminide coating, removing material forming the diffusion layer, applying a new metallic layer (32) to the metallic substrate, and applying a new aluminide coating (28B) over the new metallic layer to form a new diffusion layer (30B) in the new metallic layer. The new metallic layer is a substantially homogeneous material that is substantially similar in chemical composition to that of the metallic substrate, and the new metallic layer (32) forms a structural layer having a thickness selected to provide a specified contour to the component.
