Preparation and Electrochemical Properties of Electrodeposited Pb-Polyacrylonitrile-WC Composite Coatings on Ti Anode

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Ti阳极上电沉积制得Pb-PAN-WV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1.5 A/dm2,温度35℃,15 g/L的PAN,40 g/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.
