Abstract
A coated article is disclosed including a substrate, a bond coating, and a thermally insulating top coating. The substrate includes a substrate surface and a substrate material at the substrate surface. The bond coating is disposed on and contacts the substrate surface, and includes the substrate material and a bond coating surface distal from the substrate surface. The bond coating surface includes a greater surface roughness than the substrate surface. The thermally insulating top coating is disposed on and contacts the bond coating surface. A method for forming the coated article includes applying the bond coating to the substrate surface, and applying the thermally insulating top coating to the bond coating surface.
