Abstract: THERMAL BARRIER COATING FOR NICKEL BASE SUPER ALLOYS Adherent, thermal shock-resistant protective coatings for nickel base super alloys are obtained by applying to the base metal a thin bond coat of an alloy of chromium, aluminum and yttrium with materials selected from the group consisting of iron, cobalt, nickel and nickel-cobalt and applying thereover a continuously graded mixture of this material with a zirconiabased ceramic, the concentration of zirconia-based ceramic increasing from the bond coat to the outer layer. The zirconia ceramic may be stabilized by the addition thereto of amounts of magnesium oxide or other materials.

Abstract: A method of coating is described wherein a nickel-, cobalt- or iron-base alloy is provided with an oxidation and sulfidation-resistant coating by depositing, to a thickness greater than one micron but less than three microns, 90-97%, by weight, of a platinum group metal selected from the group consisting of platinum, palladium, rhodium, ruthenium, osmium and iridium and 3-10%, by weight, of an active metal selected from the group consisting of Y, Hf, and Zr onto the alloy and subsequently aluminizing the coated substrate
