发明名称 Modified diffusion aluminide coating for internal surfaces of gas turbine components
摘要 An article is formed of a gas turbine component having a substrate, an internal passage through the substrate defining an internal surface of the substrate, and an internal protective layer overlying the internal surface of the substrate. The internal protective layer has a composition of aluminum, plus, in weight percent, on average from about 0.1 to about 5.0 percent of a modifying element selected from the group consisting of hafnium, yttrium, zirconium, chromium, and silicon, and combinations thereof, and elements found in the substrate.
