摘要	The oxidation behavior of WE43 magnesium alloy in dry air at three temperatures (225, 440 and 525 degrees C) and the corresponding corrosion performance of samples attached to oxide film in 3.5 wt% NaCl solution was investigated. The results show that the oxide films formed at all three temperatures are a complex MgO center dot RE2O3 center dot ZrO film with different compositions. The film formed at 225 degrees C is flat and dense, whose components are 3.2MgO center dot 1.8RE(2)O(3)center dot 1ZrO. The oxidation ridges begin to form, and then gradually grow into nodular oxides and form a loose and porous oxide layer as the temperature increases to 525 degrees C. The oxide films formed at all three temperatures improve the corrosion resistance of the alloy due to the MgO center dot RE2O3 center dot ZrO, with the protective properties of oxide films following the order of 225 degrees C > 440 degrees C > 525 degrees C, because the dense MgO center dot RE2O3 center dot ZrO film formed at 225 degrees C can provide better protection to the substrate than the loose oxide film formed at higher temperatures.
