摘要：
A Pt—Al—Hf/Zr aluminide coating that can be used as a bond coat for TBC and improve TBC spallation life in service at elevated temperatures is provided. The aluminide coating can include a metastable ternary or higher X—Pt/Pd—Ni phase where the phase and other elements in the alloy system are present in a NiAl β phase of the coating. The metastable phase can be present and observable in the as-deposited condition of the bond coating; e.g. in an as-CVD deposited condition of the bond coating.
