    摘要:

    利用磁懸浮水冷銅坩堝冶煉四元Ni-Ti-Nb基形狀記憶合金,對板材試樣模擬其典型的介質-人體組織液和人工海水,運用MJontaklo mode測定陽極極化曲線,并對該體系合金純化膜進行了耐蝕行為評價。結果表明:Ni-Ti-Nb基形狀記憶合金具有良好遙耐蝕性。合金化元素Zr提高其耐蝕性,Cr降低其耐蝕性,而V對該行為影響不大。

    Abstract:

    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.
