摘　　要：镁及镁合金的降解行为使得它作为生物可降解植入材料有很大的吸引力,并且其具有合适的力学性能和良好的生物相容性。目前,镁及镁合金作为可降解医用材料的应用研究基本上集中于心血管支架、骨固定材料、多孔骨修复材料、牙种植材料、口腔修复材料等方面的研究。但是镁合金存在腐蚀速度过快的问题,因此,对镁及镁合金腐蚀本质的研究以及表面改性技术的完善成为其在生物材料领域应用的关键。The degradation action of magnesium and its alloys makes them very attractive for biodegradable implants, and they have appropriate mechanical properties as well as good biocompatibility. To date, magnesium and its alloys have been used as degradable medical materials mainly in cardiovascular stent, bone fixation material, porous bone repair materials, tooth implantation materials, and prostbodontic materials. However, magnesium alloys are rapidly corroded. Therefore, studies on corrosion of magnesium and its alloys and improvement of surface modification technique have become focus in biomaterial field
