摘　　要：镍钛形状记忆合金(NiTi-SMA)具有较好的耐腐蚀和机械性能,在口腔和临床医学中有着大量而广泛的应用。NiTi-SMA腐蚀后释放Ni^(2+)会引发细胞毒性和过敏反应,进一步提高NiTi-SMA的耐蚀性是目前生物医学材料领域发展的核心之一。本文对近年来国内外有关口腔医学和临床医学中常用NiTi-SMA的腐蚀研究现状进行了总结,同时也对NiTi-SMA增材制造及表面改性技术进行了评述,以期为开发高性能抗腐蚀生物医用NiTi-SMA提供一定的指导。Due to good corrosion resistance and mechanical properties,NiTi shape memory alloy(NiTi-SMA)has been widely used in oral and clinical medicine.However,the release of Ni^(2+)after NiTi-SMA corrosion can trigger cytotoxicity and allergic reactions.Improving the corrosion resistance of NiTi-SMA is one of the key technologies in biomedical materials field.In this paper,the corrosion status of NiTi-SMA commonly used in oral and clinical medicine in recent years was summarized.At the same time,the additive manufacturing and surface modification of NiTi-SMA technology was also reviewed in order to provide some guidance for the development of high performance anti-corrosion NiTi-SMA.
