    摘要:

    為進一步改善TC4合金性能，尤其耐海水腐蝕性，采用自耗電極真空電弧熔煉（VAR）法在TC4合金基體中加入Cu和Ag，制備分別含1%、2%Cu（質(zhì)量分數(shù)，下同）的TC4-Cu和含1%Ag的TC4-Ag合金。利用電化學方法研究了不同合金在人工海水中的腐蝕行為與特征。結(jié)果表明，添加Cu和Ag后，TC4合金在人工海水中的腐蝕電位升高，腐蝕電流減小，可以有效提高TC4合金的耐腐蝕性能。

    Abstract:

    To further improve the performance of TC4 alloy, especially corrosion resistance to the seawater, 1wt%, 2wt% Cu and 1wt% Ag were added into TC4 alloy to fabricate three kinds of alloys of TC4-Cu and TC4-Ag with VAR. The corrosion behavior and characteristics of different kinds of alloys in artificial seawater were researched by electrochemical methods. The result shows that the corrosion potentials of TC4 with addition of Cu and Ag are raised and their corrosion currents are decreased, so the corrosion resistance of TC4 alloy can be improved effectively.
