采用注入不同剂量5×1016,1×1017,5×1017和9×1017ions/cm2,加速电压30kV对Ti6Al4V合金进行Ag离子注入表面改性.使用动电位极化曲线研究Ag离子注入前后Ti6Al4V合金抗Hank's溶液腐蚀性能,利用小角掠射X射线衍射技术研究Ag离子注入前后Ti6Al4V合金表面物相组成,用X射线光电子能谱技术分析离子注入合金表面和腐蚀样品表面元素存在的化合态.结果表明,Ag离子注入提高了合金抗Hank's溶液腐蚀性能,腐蚀电流密度随Ag离子注入剂量的增加稍有变化.离子注入Ti6Al4V合金表面的氧化物腐蚀阻挡层、离子注入表面合金层和表面生成的Ag和TiAg有利于合金抗Hank's溶液腐蚀性能的改善.
