Bond coat process for thermal barrier coating

Methods provide for depositing a bond coat of a thermal barrier coating (TBC) system for a component designed for use in a hostile thermal environment. The method includes providing an article substrate having a substrate surface, forming a bond coat on the substrate by depositing a beta-phase Ni-Al...

Zusammenfassung:	Methods provide for depositing a bond coat of a thermal barrier coating (TBC) system for a component designed for use in a hostile thermal environment. The method includes providing an article substrate having a substrate surface, forming a bond coat on the substrate by depositing a beta-phase Ni-Al bond coat by cathodic arc deposition, processing the bond coat by peening to improve the coating structure, and heat treating the bond coat. Also disclosed is a turbine blade comprising a nickel-base superalloy substrate, a bond coat on the surface of the substrate, and a ceramic thermal barrier coating overlying the bond coat surface.
