    摘要:

    采用失重法和電化學(xué)測試研究了Ａｌ、Ｍｏ、Ｚｒ合金添加元素對Ｔｉ－Ｔａ合金在高溫濃ＨＮＯ３溶液中耐蝕性的影響以及溶液中Ｒｕ３＋的作用。結(jié)果表明：在Ｔｉ－Ｔａ合金中加入Ａｌ、Ｍｏ元素，則降低合金的耐蝕性能；添加Ｚｒ，合金的抗腐蝕性能有所提高；溶液中的Ｒｕ３＋可以加速所研合金的鈍化，提高合金的抗蝕能力。電化學(xué)測試結(jié)果與腐蝕試驗完全一致。

    Abstract:

    The influnces of adding AL Mo and Zr elements on corrosion resistance of Ti-Ta alloy in boiling 40% nitric acid solution, and the effect of Ru3+adding into the solution on the alloys have been researched by immersion tests and electrochemistry method.The results show that the corrosion resistances of the alloys are reduced slightly after adding Al and Mo elements in Ti-Ta alloy,and the corrosion resistance is increased by adding Zr.The passivations of all researched alloys are promoted by R3+in solution,and the corrosion resistances of the alloys are increased.The results of elechro-chemical means agree completely with corrosion test.
