摘要： A slurry and slurry coating process for forming a diffusion aluminide coating on a substrate, including internal surfaces within the substrate. The process involves preparing a slurry of a powder containing a metallic aluminum alloy having a melting temperature higher than aluminum, an activator capable of forming a reactive halide vapor with the metallic aluminum, and a binder containing an organic polymer. The slurry is applied to surfaces of the substrate, which is then heated to burn off the binder, vaporize and react the activator with the metallic aluminum to form the halide vapor, react the halide vapor at the substrate surfaces to deposit aluminum on the surfaces, and diffuse the deposited aluminum into the surfaces to form a diffusion aluminide coating. The process can be tailored to selectively produce an inward or outward-type coating. The binder burns off to form an ash residue that can be readily removed.

摘要： A casting process for producing metal alloy castings, facecoats and apparatuses suitable for carrying out the process, and castings produced by the process. The casting process entails the use of a mold having a cavity with a continuous aluminum-containing solid facecoat on its surface. A molten quantity of a metal alloy is introduced into the mold cavity so that the molten alloy contacts the solid facecoat. The mold is then allowed to cool to solidify the molten alloy and form a cast product. During the casting process, aluminum in the solid facecoat diffuses into the cast product to form an aluminum-containing surface region at the casting surface. Following removal of the cast product from the mold, an alumina-containing scale grows on the casting surface as a result of oxidation of the casting surface region.

摘要： A method and coating for maintaining surface-related properties of a gas turbine combustor component having a wall formed of a nickel-base alloy containing a gamma prime precipitate strengthening phase, interior and exterior surfaces defined by the wall, and at least one hole in the wall that fluidically connects the interior and exterior surfaces of the combustor component. A diffusion coating composition is applied at least within the hole, and then heated to form a diffusion aluminide coating in at least an in-wall surface region of the wall that surrounds and defines the hole. The aluminiding coating forms a diffusion zone that contains a sufficient amount of aluminum intermetallics to inhibit depletion of the gamma prime precipitates in the wall and inhibit degradation and cracking in the in-wall surface region surrounding the hole.
