摘　　要：交叉轧制的合金材料各向异性明显减小,性能较好,目前将其用作电积铜阳极并对其耐蚀性能进行研究的报道较少。采用恒电流极化曲线、循环伏安曲线、交流阻抗曲线、X射线衍射、扫描电镜等测试手段研究了不同Sn含量交叉轧制8次的Pb-Ca-Sn合金的性能。结果表明:随着Sn含量的增加,合金的耐腐蚀性和导电性逐渐增加,析氧过电位逐渐降低,其中Pb-Ca-(1.20%)Sn合金的综合性能最好。Properties of Pb-Ca-Sn alloys with different Sn contents after cross- rolling for 8 cycles were investigated based on the measurements of galvanostatic polarization curves,cyclic voltammetry curves,electrochemical impedance spectra in association with X-ray diffraction analysis and scanning electron microscopic observation.Results indicated that the corrosion resistance and electrical conductivity of Pb-Ca-Sn alloys tended to increase with elevating Sn contents,while the oxygen evolution over potential declined therewith.Particularly,the Pb-Ca-Sn alloy anode containing 1.20%Sn exhibited the best comprehensive performance.
