ABSTRACT:
A heat resistant stainless steel coated by diffusion of aluminum and a method of aluminum diffusion coating for heat resistant stainless steels containing nickel and chromium. The stainless steel is buried in a diffusion coating pack powder composed of an aluminum source, an activator and inert filler materials. The coating is heat treated to form a chromium-rich intermediate layer without forming an interdiffusion layer containing aluminide precipitates under an aluminide layer.
