以1060铝为基体,在由Pb(CH3COO)2 220 g/L,HBF4170 g/L,H3BO314g/L,明胶2g/L,十六烷基三甲基溴化铵0.5～1.0 g/L组成的基础镀液中,电沉积制得Pb-WC-CeO2复合镀层.通过测定其作阳极电解锌时的塔菲尔曲线,研究了WC和CeO2颗粒的质量浓度、电流密度、温度及搅拌速率对Pb-WC-CeO2复合镀层耐蚀性的影响,得到最佳工艺为:WC 40 g/L,CeO230g/L,温度40℃,电流密度40 mA/cm2,搅拌速率350 r/min.Pb-WC和Pb-WC-CeO2的腐蚀电位分别比纯铅镀层正0.005 V和0.050 V.Pb-WC-CeO2镀层表面最为均匀细致,耐蚀性最强.
