摘要
利用磁悬浮水冷铜坩埚冶炼四元 Ni- Ti- Nb基形状记忆合金 ,对板材试样模拟其典型的应用介质 -人体组织液和人工海水 ,运用 Montaklo mode测定阳极极化曲线 ,并对该体系合金钝化膜进行耐蚀行为评价。结果表明 :Ni-Ti- Nb基形状记忆合金具有良好的耐蚀性 ;合金化元素 Zr提高其耐蚀性 ,Cr降低其耐蚀性 ,而 V对该行为影响不大。
Some ternary Ni Ti Nb based shape memory alloys have been prepared in the water cooled crucible of a magnetic suspension furnace under a controlled protective argon atmosphere. Anodic polarization curves of the Ni Ti Nb based shape memory alloys were measured utilizing the Montaklo Mode. The stability of the passive film was investigated in both artificial sea water (3 5%NaCl) and physiological solution (5%NaCl+0.1%H 2O 2) environments. The results show that the corrosion resistance of these alloys is excellent.
