| Abstract: |
| This article makes a comprehensive summary about the research of PVD coatings on the corrosion resistance of magnesium alloy at home and abroad in recentyears,and put forward that:PVD coatings canimprove magnesium alloy's corrosion resistance by reducing the corrosion current; The main cause of coating's invalidation is due to the structural defects such as pores in the coatings acting as a corrosion channel; The corrosion resistance of coating/substrate system can be enhanced by minimizing these defects through coating's structural design,process parameters' optimization and so on. |
