| Abstract: |
| A new stream of surface treatment technologies for magnesium alloys , depositing aluminum on magnesium alloy, is summarized on the basis of recent laboratory experiments. The strong points and weak point of traditional magnesium alloy surface treatment technologies were analyzed and the advantages of aluminum coating on magnesium alloy were explained. The latest aluminum coating depositing technologies on magnesium alloy varies from diffusion between aluminum powder and magnesium alloy matrix at high temperature to thermal spraying aluminum powder or thread materials with both traditional and advanced spraying equipments. Based on the understanding to different technologies, the corrosion-resistant mechanism of aluminum coating on magnesium alloys was further discussed. Finally, the application foreground of the technology in question was predicted and the major problems limiting its development were put forward. |
