OXIDATION RESISTANT COMPONENTS WITH IMPROVED HIGH TEMPERATURE STRENGTH AND RELATED METHODS

摘要

An oxidation resistant component with high temperature strength and a method of creating such component are disclosed. A modified base metal may be formed by adding at least two strengthening additives to a base metal, the base metal being substantially free from both nickel and cobalt and comprising from about 1% to about 27% chromium by weight. The modified base metal may then be formed into a component and an aluminum-containing slurry may be applied to a surface of the component. The component may then be heated to diffuse aluminum into the component and to form an aluminum diffusion surface layer therein.
