在 Al／Pb／α-PbO2-WC 表面恒电流电沉积制备了β-PbO2-WC（Co3 O4）复合沉积层，获得了 Al／Pb／α-PbO2-WC／β-PbO2-WC（Co3 O4）复合材料。考察了 WC（碳化钨）、Co3 O4（四氧化三钴）颗粒的掺杂对β-PbO2复合材料物理性能及其在锌电积模拟体系中的耐蚀性、析氧电催化活性、交流阻抗特性的影响。结果表明：WC 与 Co3 O4颗粒在β-PbO2中的掺杂提高了复合材料的显微硬度，降低了电阻率及锌电积模拟体系中的析氧过电位，增强了锌电积模拟体系中的耐腐蚀性能。

β-PbO2-WC (Co3 O4 )composite deposition layers were prepared on the surface of Al/Pb/α-PbO2-WC substrates by con-stant current electrodeposition,yielding Al/Pb/α-PbO2-WC/β-PbO2-WC (Co3 O4 )composites.The effects of the doping of WC (tungsten carbide)and Co3 O4 (cobaltosic oxide)particles on the physical properties ofβ-PbO2 composites and corrosion resist-ance,oxygen evolution electrocatalytic activity,AC impedance characteristics in the simulated system of zinc electrowinning were investigated.The results show that the doping of WC and Co3 O4 particles intoβ-PbO2 increases the microhardness,decreases the resistivity and oxygen evolution overpotential,enhances the corrosion resistance ofβ-PbO2 composites in zinc electrowinning sim-ulated system.
