摘要
The 1200℃ steam oxidation behaviors of CrAl coating with components deposited on Zr-4 were studied .The Cr70Al30 coating showed the best antioxidant properties .The Cr coating showed superior protection with a continuous Cr2O3 oxide layer .The Cr50Al50 coating exhibited partial protective properties，and presented continuous Cr2O3 and Al2O3 oxide layers .The Cr30Al70 coating had poor antioxidant resistance, with a large number of defects emerged on oxide layer. The effects of Al diffusion and partical concentration oxidation resistance were discussed in detail.
