摘要(Abstract)：

采用非自耗真空电弧炉制备了Ti-49Zr-21Nb-xSn (x=0、0.5、1.0、2.0和4.0 mass%)合金。借助X射线衍射仪(XRD)、扫描电镜(SEM)、万能试验机、电化学工作站及X射线光电子能谱(XPS)等研究了不同含量Sn元素对合金显微组织、力学性能及腐蚀性能的影响。结果表明：随着Sn元素含量的增加，合金的晶粒明显细化，相组成主要为β相，当Sn元素含量超过2%时，在晶界析出(Ti+Zr)_5(Nb+Sn)_3相。合金的强度随Sn元素含量的增加先升高后降低，当Sn元素含量为1%时，合金的抗拉强度和屈服强度达到最大，分别为1121和1085 MPa,且伸长率为23.9%。未添加Sn元素时，合金的耐蚀性最佳，添加Sn元素后，合金的耐蚀性逐渐降低，当Sn含量为1%时，合金的自腐蚀电流密度较低，耐蚀性较好。因此，Ti-49Zr-21Nb-1Sn合金具有高的力学性能和较好的腐蚀性能，作为生物医用材料表现出了良好的综合性能。
