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。 Four-dimensional Ni-Ti-Nb base shape memory alloy was smelted in a maglev water-cooled copper crucible. The plate samples were used to simulate the typical application medium - human tissue fluid and artificial seawater. The anodic polarization curve was measured by Montaklo mode. The corrosion resistance of the film was evaluated. The results show that Ni-Ti-Nb based shape memory alloy has good corrosion resistance; alloying element Zr enhances its corrosion resistance, Cr decreases its corrosion resistance, while V has little effect on this behavior.
