摘　　要：NiTi合金因其独特的形态记忆性、超弹性等特点被广泛应用于临床,但随着合金的植入,镍离子在机体内被溶解释放,该离子可导致机体致敏及毒性反应,而如何减少镍离子溶出的问题已在业内被广泛研究。同时,已经通过多种方法对镍钛合金进行表面改性,并制备出了不同的具有生物相容性的合金材料,本文将对该领域取得的成就进行综述。As the unique shape memory effect and superelasticity, NiTi alloy was widely used as biomaterials. When the alloy was implanted into the body, the Ni ion can be released, which can lead to allergic reactions and toxic effects. So, it has been received more and more attentions nowdays how to reduce Ni ion emissions. In addition, the biocompatible of NiTi alloys was invented by diverse surface modification. The achievements were summarized.
