摘要： A method for applying a coating (26) includes: providing a mixture of MCrAlY; Cu; Mo; and BaF2 powders; and spraying the mixture on a metallic substrate (22). A heat treating in an oxidizing atmosphere may form at least a surface layer of: BaCrO4; BaMoO4; CuTa2O6; CuzO; and CuO. The substrate (22) may form a seal such as a split ring seal.
