摘　　要：利用线性电位扫描、恒电位阶跃、交流阻抗等方法分别研究了Pb Ca Bi合金被阳极或阴极极化后,表面上析氧、析氢以及合金腐蚀行为。结果表明:与Pb Ca合金相比,Pb Ca Bi合金可增加氧的析出,但抑制氢的析出,同时铋的加入,使Pb Ca耐蚀性提高,且不同含量的铋对合金腐蚀有不同的影响。The evolution behavior of hydrogen and oxygen when cathodized,and its corrosion on the surface of the Pb-Ca-Bi alloys when anodized by linear potential scan, constant potential steps, impedance spectras methods. The results showed that bismuth in the Pb-Ca alloys could decrease the rate of hydrogen evolution.There were different effects on oxygen evolution reaction for different contents of bismuth.Bismuth in suitable quantity could improve Pb-Ca alloys corrosion resistance, bismuth in different content had different effect on grid corrosion.
