Diffusion aluminide coating process

摘要

A method of applying a diffusion aluminide coating partially to a selective region more simply and conveniently, the method including (a) a step of forming a metal aluminum film onto a selective region of the heat-resistant alloy substrate to be treated; and (b) a step of applying a heat treatment to the heat-resistant alloy substrate on the selective region of which the metal aluminum film is formed and diffusing and penetrating aluminum in the metal aluminum film into the heat-resistant alloy substrate.
