Abstract: The history of anodic oxidization on magnesium and its alloys was simply reviewed, and its treating process, compositions and functions of electrolyte were introduced comprehensively. In addition, the mechanism of oxidization on magnesium was discussed. With the development of human awareness on environmental protection and the scarcity of world resources and upgrade of anodization equipment, the effects of electric parameters on properties of anodic coating, measurement of current efficiency, study of diffusion regularity for anodic coating formation and development of environmentally friendly electrolyte were put forward about anodization.
Key words: magnesium alloys; corrosion and protection; anodization; electrolyte; mechanism
