Abstract
The Al/Pb-0.3wt%Ag-0.01wt%Co and Al/Pb-0.3wt%Ag composite anode materials were prepared by electrodeposition. The electrochemical properties of the composite anode in 50 g/L Zn2+ and 150 g/L H2SO4 solutions were investigated by anode polarization curves, cyclic voltammetry (CV) curves and Tafel curves. The surface structure was characterized by SEM and EDS. The results show that the cobalt addition can reduce the oxygen evolution potential and improve the corrosion resistance. Compared with cast Pb-0.3wt%Ag, the anodized layer of the Al/Pb-0.3wt%Ag and Al/Pb-0.3wt%Ag-0.01wt%Co are more dense, the grains are finer.
