Both experimental results of isothermal okidation at 1000℃ for 48h and cyclic oxidation at 900℃ for 330 h showed that the poor oxidation resistance of the intermetallics was significantly improved after the intermetallics was coated with the composite film. SEM/EDX and EPMA results indicated that the preferentially formed La2O3-modified NiO layer on the Ni-La2O3 electrodeposited composite film could block growth of TiO2 out of the surface scale and favor the formation of two continuous protective Al2O3 layers. The two alumina layers, one beneath the La2O3-modified NiO layer and the other close to the subsurface zone in the substrate, are responsible for maintenance of the superior oxidation resistance of the coated γ-TiAl during the long-term thermal cycling.
