摘要：

This study indicates that the kinetic rate constants of oxidation weight gain and thickening both increase with the increasing content of O, N and S impurities. The oxide layer of the low-purity alloy is not tight and easy to peel off. Internal oxidation becomes more serious with the increase of oxygen solubility. The microscopic mechanism of how impurity atoms affect the oxidation diffusion process was explained, and the models of the oxide layer growth process for high-purity alloys and low-purity alloys were constructed, which provide a reference for the improvement of high-temperature oxidation performance of superalloys in the future.
