摘　　要：本文在TiNi合金表面进行W离子注入,研究了W膜层的表面形貌、物相组成和粗糙度及TiNi合金注W前后在Hank's溶液中的Ni离子析出情况和动电位阳极极化曲线。研究表明离子注W显著抑制了TiNi合金在Hank's溶液中Ni离子的析出,提高了TiNi合金的耐腐蚀能力。In the paper,W ion was implanted into the surface of Ti Ni alloys,and the surface morphology of W layer,phase composition and roughness were researched,as well as the precipitation of Ni ion in Hank＇s solution and the potentiodynamic anodic polarization curves before and after W implantation were researched. The results show that W ion implantation can inhibit evidently the precipitation of Ni ion from Ti Ni alloys in Hank＇s solution and improve the corrosion resistance of Ti Ni alloys.
