Research progress on properties of micro-arc oxidation ceramic oxide film modified by micro/nanoparticle on magnesium alloys
Magnesium alloys have extensive application prospects in fields,such as aerospace and 3C electronic products due to their low density,high specific strength,excellent electromagnetic shielding performance and recyclability.However,the high chemical reactivity of magnesium alloys makes them prone to corrosion and limited wear resistance,which restricts their applications.The micro-arc oxidation technique is widely regarded as an effective method to address these issues by generating ceramic oxide coatings on the surface of magnesium alloys,thereby improving their wear resistance and corrosion resistance.This article provided a summary of the recent research progress on the performance of micro/nano-particle-modified magnesium alloy micro-arc oxidation coatings.The formation mechanism of micro-arc oxidation coatings on magnesium alloys was briefly introduced,with a focus on key indicators,such as coating structure evolution,friction and wear performance,and corrosion resistance.The research direction for developing high-performance surfaces of magnesium alloys using micro-arc oxidation technique was presented,offering valuable references for future research and promoting the application and development of magnesium alloys.
