Abstract:

Magnesium has good biocompatibility，biodegradation and proper mechanical properties and thereby has the potential to be used as biomedical materials. In this paper，the merits and shortcomings of magnesium as biomaterials are evaluated. Furthermore，different surface modification technologies，including electrochemical deposition and cathodic deposition，plasma immersion ion implantation and ion plating，anodization and micro-arc oxidation，chemical conversion to make coatings on magnesium and its alloys also are reviewed. The influence of as-prepared coating on corrosion properties and bioactivity is described. The prospects of magnesium as a new-type biodegradable hard tissue implant are presented.

摘要：

由于镁具有优异的生物相容性、可生物降解性及适宜的力学性能而成为潜在的生物医用材料。本文对镁作为生物材料的优缺点进行了综合的评价，分类综述了用不同的表面改性技术在镁及其合金表面制备不同的涂层，包括电化学沉积法及阴极沉积法、离子注入及离子电镀法、阳极氧化及微弧氧化法以及化学转化法，评述了这些涂层对镁的腐蚀性能与生物活性的影响，并对镁作为一种新型可降解的硬组织植入材料的应用前景进行了展望。
