Abstract:
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 Ni2+ 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.
