摘要	A Ni + CrAlYSiN composite coating was prepared on a Ni-based superalloy K417 by vacuum arc evaporation, mainly consists of nanocrystalline gamma-Ni, fcc-AlN and fcc-CrN. The oxidation behaviour of the specimens in air at 1000 degrees C for 100 h was studied. A double-layer oxide scale, inner Al2O3 layer and outer mixture layer mainly dominated by NiCr2O4, formed on the composite coating. Substantial interdiffusion between the composite coating and the substrate was observed. In contrast, a unique alumina scale formed on the composite coating with a nanocrystalline hcp-AlN barrier layer, and the interdiffusion between the composite coating and the substrate was undetectable.
