摘　　要：镁合金是一种生物相容性良好,潜在市场需求巨大的生物医用材料。但由于其降解速率太快,成为其扩展应用的瓶颈。本文综述了镁合金主要采用的改性技术:纯化镁合金、镁合金的合金化、镁合金的热处理、镁合金的表面处理;其中主要对比了各种镁合金的表面改性方法,分析了各种方法的优缺点,为持续改善镁合金的降解性能提供一定的参考,并对其未来进行了展望。Magnesitm alloys are biomedical material which have good biocompatibility and huge potential market demand. However, fast degradation rate became the bottleneck of lheir expanding application. This paper reviews the mainly modification technology of magnesium alloys ： purification on magnesium alloy, alloying of magnesium alloy, heat treatment, surface treatment of magnesium alloys; It compares the various surface modifieation methods of magnesium alloys. It analyzes the advantages and disadvantages of various methods .This paper provides certain reference for continuous improvement of degradation on magnesium alloys. And the future of magnesium alloys was prospected
