摘　　要：综述了阳极氧化技术在增强Mg及其合金耐蚀性和有关Mg阳极氧化现象。In this paper, the progress of anodizing technology for magnesium and its alloys is overviewed.Corrosion resistance of Mg and its alloy maybe efficiently enhanced by anodizing,the technology of which embodies mainly in variation of electrical parameters such as voltage and cunent while anodizing. Namely,the operating voltage is being raised toward higher values and the present constant voltage operation is being challenged by constant current operation. At the same time, simple alternating current or direct current electrical signals utilized during anodizing are being changed to sophisticated puls signals or their superposed signals. On the other hand, the change of electrolyte composition is also an important aspect of the development of the technology. The investigation actuality emphasized to the anodizing of magnesium and its alloys includes phenomena and mechanisms of the formation of anodizing coatings as well as their constituents and morphologies which are related to their protectiveness
