英文摘要	High temperature oxidation behavior of the Cr2AlC coating was investigated at 900-1100 degrees C. During the oxidation, a continuous Al2O3 scale formed, resulting in the improvement of the oxidation resistance of the substrate. Meanwhile, the oxidation induced depletion of Al within the Cr2AlC coating resulted in the transformation of Cr2AlC to Cr-C phases. Compared with bulk Cr2AlC, the Cr2AlC coating possessed similar oxidation behavior, but with higher oxidation rate. This is because a great number of columnar grain boundaries existed in the as-deposited coating, through which oxygen and nitrogen could diffuse inwardly, resulting in the internal oxidation and nitridation.
