Abstract The oxidation behavior of a rare earth containing heat-resistant Mg-alloy Mg-14Gd-2.3Zn-Zr was studied in air for 20 h at 200 and 300 ℃, and for 50 min at 440 ℃, respectively. The surface morphology and phase composition of the oxide scales were characterized by means of XRD, SEM and EDS. The results show that the formed oxide scales were mainly composed of MgO. As the oxidation temperature increases, beneath the oxide scale, the Gd content in the surface of the substrate gradually increased. Of particular note is the formation of an intermediate layer of continuous and dense Gd2O3 in between the oxide scale and substrate, which can prevent the further consumption of Mg2+ in the substrate alloy, thereby increasing the oxidation resistance of the Mg-alloy.
