To summarize the research progress of biocompatibility and surface modification of nickel titanium shape memory alloys (Ni-Ti SMA).
The relative researches about Ni-Ti SMA at home and abroad were reviewed, collated, analyzed, and summarized.
At present, Ni-Ti SMA as an internal fixation material has been widely used in clinic. It has the following advantages: the super elasticity, the shape memory characteristic, the good wear resistance, and the strong corrosion resistance. It also can effectively avoid the internal fixator rupture caused by stress shielding. After surface modification, the biocompatibility of Ni-Ti SMA has been improved.
The Ni-Ti SMA is the most promising alloy material for the long-term internal fixator because of its excellent material properties.
总结镍钛形状记忆合金（Ni-Ti SMA）生物相容性及表面改性的研究进展。
对国内外关于Ni-Ti SMA的相关研究进行回顾、整理、分析及总结。
目前，Ni-Ti SMA作为内固定材料已在临床广泛应用。它具有以下优点：超弹性、形状记忆特性、良好的耐磨性及较强的耐腐蚀性。还能有效避免应力遮挡导致的内固定器断裂。表面改性后，Ni-Ti SMA的生物相容性得到了改善。
Ni-Ti SMA因其优异的材料性能，是最具前景的长期内固定合金材料。
