Abstract
An improved thermal barrier coating system is described. A key feature of the invention is the presence of a thin, adherent aluminum oxide scale on the surface of the substrate. An oxide stabilized ceramic coating is present on the surface of the scale. Preferably, the ceramic coating has a columnar grain structure.
