摘要	A composite coating (MCrAlY+AlSiY) was prepared on a Ni-based superalloy K465 by arc ion plating technique. The oxidation behaviors of the composite coating and the reference coating NiCoCrAlYSiB were investigated. The results show that the outer layer of composite coating consists of beta-(Ni, Co)Al and dispersed sigma-NiCoCr and Cr(3)Si, and the inner layer of composite coating consists of Cr-rich phases and minor beta-(Ni, Co)Al after vacuum annealing at 1050 degrees C. Because of the excessive consumption of Al, the spinels and NiO are formed on the surface of the reference coating. For the composite coating, the protective alumina scale is continuous and dense. The enhanced oxidation resistance of the composite coating is related to the gradient distributions of Al-enriched outer layer and Cr-enriched inner layer.
