The research progress on micro-arc oxidation of aluminum alloy

Abstract

The micro-arc oxidation of aluminum alloy is a kind of surface treatment technology for in-situ growth of a hard ceramic film with Al2O3 as the main effect of instantaneous high temperature and high pressure generated by arc discharge on the surface of aluminum alloy. This technology can significantly improve the wear resistance, corrosion resistance, hardness and other properties of the aluminum alloy matrix. This paper introduces the characteristics, influencing factors, research status of domestic and foreign micro-arc oxidation technology, and prospects for future research directions.
