Patent ID: 7029721

Claim:
A method for applying a bond coat on a metal-based substrate, comprising the following steps: a) applying a slurry which comprises braze material to the substrate, wherein the slurry also contains a volatile component, and wherein the braze material has an avenge particle size in the range of about 20 microns to about 150 microns; b) applying bond coat material to the substrate, wherein the slurry comprising the braze material further comprises the bond coat material, so that the braze material and the bond coat material are applied to the substrate simultaneously, wherein said bond coat material comprises at least one material selected from the group consisting of aluminide; platinum-aluminide; nickel-aluminide; platinum-nickel-aluminide; an alloy of the formula MCrAlX, where M is selected from the group consisting of Fe, Ni, Co, and mixtures of any of the foregoing and where X is selected from the group consisting of Y, Ta, Si, Hf, Ti, Zr, B, C, and combinations thereof; and any combination of the foregoing; c) drying the slurry and bond coat material to remove at least a portion of the volatile component; and d) fusing the braze material and bond coat material to the substrate.
