Abstract
The present invention relates to a thermal barrier coated article with spallation and delamination inhibiting metallic bond coat. The metallic bond coat contains a reactive element oxide, preferably yttria, which reacts with sulfur, typically migrating from the substrate to the thermal barrier coating, to prevent the sulfur from inducing spallation of the oxide scale at the interface of the thermal barrier coating and the metallic bond coat. This metallic bond coat is preferably multi-layered having a reactive element oxide containing layer sandwiched between two reactive element oxide-free layers.
