摘要	The temperature dependence on the oxide layer and the oxidation mechanism was systematically investigated at 900 degrees C and 1000 degrees C in a low-cost second-generation Ni-based single crystal superalloy. The oxidation kinetics could be divided into three stages. The initial stage followed a parabolic law with an activation energy of 60.08 kJ mol-1. A linear law was observed in the second stage due to the formation of Al2O3. However, the last stage showed different trends, following an almost flat linear law at 900 degrees C, while an abnormal increase was observed at 1000 degrees C. The difference was attributed to the rapid growth of intermediate layer at 1000 degrees C, while the slight increase at 900 degrees C resulted in higher growth stress at 1000 degrees C. Meanwhile, the thermal stress was generated during the cooling process of specimens, which promoted the spallation of the oxide layer. As a result, the spallation of the oxide layer was more severe at 1000 degrees C, causing the abnormal increase of oxidation kinetics at this stage.
