PROBLEM TO BE SOLVED: To provide a method for depositing a bond coat of a thermal barrier coating (TBC) system for a component designed for use in a hostile thermal environment. SOLUTION: The method comprises: providing an article substrate 32 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.
