Abstract

Magnesium alloys are easy to corrode in the natural environment.Although the corrosion resistance of magnesium alloys can be improved significantly by many surface protection technologies,their surface conductivity will also be affected,which limits their application in the shell structure of 3C electronic products.Therefore,it is necessary to adopt appropriate surface protection technology to conduct corrosion-resistant and conductive treatment on magnesium alloys.In this paper,several corrosion-resistant and conductive protection technologies of magnesium alloy in recent years,such as chemical conversion,electroplating / electroless plating,magnetron sputtering and organic coating were reviewed.Then,the latest research progress of various technologies in the field of corrosion resistance and electrical conductivity protection of magnesium alloys was introduced.Finally,the main problems faced by these research technologies and the main development trends in the future were summarized and prospected.

Key words： magnesium alloy; surface protection; corrosion resistance; electrical conductivity
