  • METHODS FOR MAKING HIGH-TEMPERATURE COATINGS HAVING PT METAL MODIFIED GAMMA-NI +GAMMA'-NI3AL ALLOY COMPOSITIONS AND A REACTIVE ELEMENT
    Publication number: 20110197999
    Abstract: A method for making an oxidation resistant article, including (a) depositing a layer of a Pt group metal on a substrate to form a platinized substrate; and (b) depositing on the platinized substrate layer of Pt group metal a layer of a reactive element selected from the group consisting of Hf, Y, La, Ce and Zr and combinations thereof to form a surface modified region thereon, wherein the surface modified region includes the Pt-group metal, Ni, Al and the reactive element in relative concentration to provide a ?-Ni+?-Ni3Al phase constitution.
