【Abstract】 The poor corrosion resistance is the primary obstacle to expand the application of magnesium alloys. In this paper, the corrosion films of pure magnesium and Mg-Al alloys in atmosphere and NaCl solution are introduced. Besides, the influence of Ca and rare earth elements on corrosion film of magnesium alloys is detailed and the development of anti-corrosion magnesium alloys is presented.更多还原
