"Oxidation Resistant Components And Related Methods"

Abstract: Oxidation resistant components and methods for creating an aluminum diffusion surface layer (10) within substantially nickel- and cobalt-free components are disclosed. An aluminum-containing slurry may be applied to a component. The component may then be heated to diffuse aluminum into the component and to form an aluminum diffusion surface layer (10) therein. The surface layer (10) may be characterized by an intermetallic aluminum-containing phase extending below the surface (12) of the component.
