Current Status of Research and Application of Micro- Arc Oxidation of Aluminum Alloys and Magnesium Alloys in China

A review was provided of the current status as well as and achievements in domestic research of micro-are oxidation of Mg alloys and Al alloys. It was pointed out that as a kind of new technique for surface treatment of metals, micro-arc oxidation (MAO) could be used to in-situ form ceramic coatings on the surface of some non-ferrons metals such as Al, Mg and Ti. It had the advantages of simple procedures, environmentally friendly process and excellent performance of anodic oxidation coatings, which made it to be extensively focused on in relevant research fields.Furtbermore, the development trend of the technique was explored, and its application foreground was prospected.
