摘要：
Complex layered oxide scales composed of a complete inner layer of alpha-Al2O3 were formed on the formerly Cr203-forming alloy Ni-8Cr-3.5Al (wt%) and the NiO-forming alloy Ni-5Cr-5Al (at%) through nanocrystallization. Due to the formation of the inner layer of alpha-Al2O3, Ni-8Cr-3.5Al (wt%) and Ni-5Cr-5Al (at%) alloys with nano-sized grain were all Al2O3-formers. The results indicated that the oxide types of Ni-Cr-Al alloys could be altered through nanocrystallization. In this paper, the mechanism of oxidation for two Al2O3-forming sputtered Ni-8Cr-3.5Al (wt%) and Ni-5Cr-5Al (at%) nanocrystalline coatings on the substrates of the same alloys was proposed based upon the interaction of Cr and Al during oxidation process.
