ABSTRACT:
The present invention provides a method to coat an article using a plating process, either electroless or electrolytic, whereby nickel is plated on the article using a solution that includes a suspension of powders or containing one or more of the following elements: Ni, Cr, Al, Zr, Hf, Ti, Ta, Si, Ca, Fe, Y and Ga. Optionally, the coating is then heat treated at a temperature above about 1600° F. for an effective amount of time to allow to homogenize the coating by allowing effective interdiffusion between the species. The level of aluminum may be altered to produce a coating of the predominantly β phase of the NiAl alloy composition. Optionally, a TBC layer is applied over the predominantly β phase NiAl alloy composition metallic bond coat.
