Abstract
The effects of superficial Y2O3 coatings on the high-temperature oxidation of nickel at 900 °C in air were evaluated. For comparison, Ni substrates with and without superficial CeO2 coating were also prepared in the same condition. The results indicate that Y2O3 or CeO2 coatings result in a significant decrease in the oxidation rate of Ni, especially the former; however the oxidation mechanisms are essentially unaffected. The thickness of Y2O3 or CeO2 coatings has little influence on the oxidation rate of Ni. The beneficial effects of Y2O3 or CeO2 on the oxidation rate of Ni were discussed.
