摘要:
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 γ-Ni+γ′-Ni3Al phase constitution.

摘要:
An alloy including a Pt-group metal, Ni and Al, wherein the concentration of Al is limited with respect to the concentration of Ni and the Pt-group metal such that the alloy includes substantially no β-NiAl phase, and wherein the Pt-group metal is present in an amount sufficient to provide enhanced hot corrosion resistance.
