Abstract
A thermal barrier coating system for high temperature nickel-based and cobalt-based superalloys includes a hardenable metallic coating on the substrate and a ceramic topcoat. The metallic coating is preferably a gamma/gamma prime hardenable nickel-based superalloy, and the ceramic topcoat is preferably zirconium oxide having from about 6 to about 20 percent yttrium oxide or from about 15 to about 40 percent cerium oxide. Optionally, there may be provided between the hardenable metallic layer and the ceramic topcoat an intermetallic coating such as a nickel aluminide.
