摘　　要：采用阳极极化曲线法、循环伏安法及交流阻抗技术研究了铜磷合金在酸性硫酸铜电解液中的电化学行为。试验测得当阳极极化小于70mV时，合金阳极的电极反应为Cu－2e→Cu2＋；而当极化大于70mV时，反应为Cu－2e→Cu2＋和Cu－e→Cu＋。The electrchemical behavior of copper-phosphorus alloy anode was studied bymeans of anedic polarization curves,cyclic voltammetry and A.C. impedance techjniques.Electstrode reaction of Cu-P alloy anode was Cu-2e→Cu2+ when overpotential was below 70 mV,ac mV,while the reaction was Cu-2e→Cu2+ and Cu - e→Cu+ when ovepotential was over 70 mV.
