英文摘要In the present study, the oxidation resistance of magnesium alloyed with Gd and Ce was investigated. The high-temperature oxidation resistance of Mg-3.5Gd-xCe (x = 0, 0.2, 0.4, 0.7 and 1.0 wt%) alloys was evaluated at temperatures between 550 degrees C and 650 degrees C. Results indicate that adding less than 0.7 wt% Ce resulted in high oxidation resistance, whereas the Ce addition exceeding 0.7 wt% deteriorated the oxidation resistance. The high oxidation resistance phenomenon is attributed to the formation of compact oxide films primarily composed of MgO, Gd2O3, and a small amount of CeO2 on the surface of Mg-3.5Gd-0.2Ce and Mg-3.5Gd-0.4Ce alloys. These compact oxide films can prevent the matrix from experiencing further oxidation. The deteriorated oxidation resistances of Mg-3.5Gd-0.7Ce and Mg-3.5Gd-1Ce alloys were found to be due to the severe internal oxidation caused by the distributed Mg12Ce phases along the grain boundaries.
