中文摘要：
通过在酒石酸钾钠体系中加入聚丙烯腈（PAN）、碳化钨（WC）和PbO固体颗粒，在盹阳极上电沉积制得Pb-PAN—WC复合镀层。主要研究了电沉积工艺条件（电流密度、温度等）对Pb—PAN-WC复合镀层沉积速度及析氧动力学参数的影响。在ZnSO4-H2SO4体系中测定的阳极极化曲线表明，最佳工艺条件及固体颗粒加入量为：电流密度1．5A／dm^2，温度35℃，15g／L的PAN，40g／L的WC。通过和纯铅镀层的阳极极化曲线和析氧动力学参数对比可知，Pb—PAN—WC复合镀层的电化学性能优于纯铅镀层。
英文摘要：
Electrode anode were prepared posited Pb-polyacrylonitrile （ PAN ） -tungsten carbide （ WC ） composite coatings on Ti by adding PAN, WC and PbO solid particles in potassium sodium tartrate system. The influences of process conditions such as current density and temperature on the depositing rate and oxygen evolution kinetic parameters of composite coated electrodes were studied. The anodie polarization curves in ZnSO4-H2SO4system show that the optimal process conditions are ： current density of 1.5 A/cm2 , temperature of 35 ℃, 15 g/L of PAN in bath and 40 g/L of WC. Comparing oxygen evolution kinetic parameters of composite coated electrodes with anodic polarization curves of pure lead coated electrode, it can be concluded that the electrochemical properties of Pb-PAN-WC composite coating is better.
