Development and applications of micro-arc oxidation technology

Abstract

The development status of micro-arc oxidation (MAO) technology at home and abroad was reviewed. The principle and process characteristics of MAO technology were primarily introduced. The influence factors for the microstructure and properties of MAO ceramic coatings as well as the applications of MAO technology were summarized. Also, the existing problems of MAO technology were analyzed, and it has been pointed out that MAO technology will be developed towards the direction of low energy consumption, treatment of ultra-large and complex light metal components and combining with other surface technologies in the future.
