摘　　要：镁及镁合金材料作为可降解生物材料,其密度与人骨密度相当,具有较高的比强度和比刚度以及相对于非金属材料的更好的塑韧性和可加工性。因此,镁及镁合金有望用于承力部位的骨组织修复。本文综述了医用镁及镁合金作为生物医用材料的表面改性技术的研究现状。Magnesium and its alloys are biomaterial that can be absorbed by human body and with high specific strength and stiffness,it has better toughness and processability comparing to nonmetals.The density of magnesium and its alloys are close to human bone tissue.So magnesium and its alloys have a broad application prospect in the load-beating site of bone tissue repair. The paper reviews the current research status on the surface modification technologies for medical magnesium and its alloys.
