Abstract: A protected article has a substrate (30) and a protective structure (33) overlying a surface (32) of the substrate (30). The protective structure (33) includes a protective layer (34) overlying the surface (32) of the substrate (30) and having an aluminum content greater than that of the substrate (30), and a bond-coat layer (40) of a bond-coat-layer metal. The bond-coat-layer metal has a bond-coat initial composition having at least about 60 percent by weight platinum, rhodium, palladium, or combinations thereof. There may be a diffusion-barrier layer between the surface (32) of the substrate (30) and the protective layer (34), and there may be a ceramic thermal barrier coating overlying the bond-coat layer (40).
