A review was provided of the current status as well as progress and achievements in domestic research of micro-arc oxida-tion of Me alloys and Al alloys. It was pointed out that as a kind ofnew technique for surface treatment of metals,micro-arc oxidation (MAO) could be used to in-situ form ceramic coatings on the sur-face of some non-ferrous metals such as Al,Mg and Ti. It had theadvantages 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. Furthermore,the development trend of the technique was ex-plored ,and its application foreground was prospected.
