A multilayer coating is deposited on a surface (44) of a nickel-base superalloy substrate (30) by depositing a diffusion aluminide coating (42) onto the substrate (30) by vapor phase aluminiding, and roughening a surface of the diffusion aluminide coating (42). The method further includes depositing by wire-arc spray a NiCrAIY bond coat (48) overlying and contacting the roughened surface (46) of the diffusion aluminide coating (42), and applying a ceramic thermal barrier coating (50) overlying and contacting the bond coat (48).
