Abstract: In this study, the WC and Co₃O₄ particles co-doped β-PbO₂ composite coatings were synthesized on a Pb-0.3wt%Ag/α-PbO₂ substrate using composite electrodeposition. The study of deposition behavior has found that WC particles are adsorbed on the substrate before Co₃O₄ particles, and co-deposition of WC particles and Co₃O₄ particles is an effective way to inhibit the agglomeration of Co₃O₄ particles when single co-deposited into β-PbO₂ matrix. Electrode performance studies have found that co-deposition of WC or Co₃O₄ particles can both improve the electrocatalytic activity of oxygen evolution of the composite anode. In addition, WC particles can also help to improve the microhardness of the composite anode and the corrosion resistance in the Zn electrodeposition solution. The co-deposition of Co₃O₄ particles is not conducive to the growth of the β-PbO₂ phase. The co-deposition of WC particles has little effect on the growth of the β-PbO₂ phase. The simultaneous co-deposition of two particles helps to inhibit the growth of the α-PbO₂ phase in the acid plating solution.
