Research Status on Friction and Wear Characteristics of Micro-Arc Oxidation Coatings Prepared by Different Methods

Abstract

Magnesium，aluminum，titanium and their alloys have been widely used in machinery，aerospace，biomedicine and other fields，owing to the advantages of high specific strength，rich resources and good processing performance.However，the disadvantage of poor wear resistance limits their applications in various fields severely.In this paper，starting from the formation principle and preparation method of the micro-arc oxidation composite coatings，the latest research statuses of friction and wear properties of coatings prepared by micro-arc oxidation composite technology on the surface of lightweight alloy materials such as magnesium alloy，aluminum alloy，titanium alloy，etc.were systematically reviewed.In addition，the current existing problems and future development direction of the micro-arc oxidation technology were pointed out，which could provide a certain reference for the follow-up research.
