摘　　要：研究了不锈钢基体上复合电沉积PbO2-WC-ZrO2复合电极材料的工艺,并通过研究固体微粒的质量浓度及各种工艺参数对PbO2-WC-ZrO2电极材料的电化学性能的影响规律。为析氧反应的阳极用复合电极材料,确定了最佳配方及操作条件:硝酸铅250 g/L、硝酸15 g/L、WC 40 g/L、ZrO250 g/L、温度20℃、电流密度3.0 A/dm2,电沉积时间2.5 h。在此条件下,可获得PbO2-(7.55%)WC-(4.10%)ZrO2复合电极材料。The electrodeposition process of PbO2- WC-ZrO2 composite electrode material on the stainless steel was studied. Based on the investigation of the effect of solid particle concentration and various technological parameters on the electrochemical performance of the electrode, the best formula and process conditions were got as follows： Pb（NO3）2 250 g/L, HNO3 15 g/L, WC 40 g/L; ZrO2 50 g/L; temperature 20℃; current density, 3.0 A/dm^2; electrodeposition time 2.5 h. On this condition, the PbO2- （7.55%） WC-（4.10%）ZrO2 codeposited electrode material can be prepared.
