摘　　要：生物医用材料具有优异的力学性能、稳定性及生物相容性等特点,被广泛应用于牙科、骨科、医疗器械等领域。但生物医用材料在使用中易出现各种感染问题,危害人体健康。微弧氧化能够在钛基、镁基等生物医用材料表面构建抗菌膜层,是有效解决感染问题的表面改性技术之一。本文概述了粒子掺入微弧氧化膜层的国内外研究现状及机理,重点综述了近年来Ag、Ag_(2)O、Cu、CuO、ZnO及其它金属氧化物粒子掺入微弧氧化膜层构建抗菌表面的最新研究动态,阐述了粒子掺入对微弧氧化膜层耐蚀性、耐磨性的影响,并对粒子掺入微弧氧化抗菌膜层的应用和发展进行了展望。Biomedical materials have excellent mechanical properties, stability and biocompatibility, and are widely used in dentistry, orthopedics,medical devices and other fields. However, various infection problems obviously occur in the current use of biomedical materials, which are severely harmful for human health and life safety. Micro-arc oxidation technology can construct antibacterial film on the surface of biomedical metal materials such as titanium and magnesium, which is one of the surface modification technologies to effectively solve the infection problem.In this paper, the research status and mechanism of particle incorporation into micro-arc oxide film were summarized. On this basis, the latest development of antibacterial surface constructed by the incorporation of Ag, Ag_(2)O, Cu, CuO, ZnO and other metal particles into micro-arc oxidation film in recent years was reviewed. The effects of particle incorporation on corrosion resistance and wear resistance of micro-arc oxidation film were described. Meanwhile, the application and development of micro-arc oxidation antibacterial film with particle incorporation were prospected.
