Abstract: We studied the anodic potential, corrosion rate, and anodic passive layer of a flat plate Pb-Ag (0.8% (mass fraction, w) anode over a long period of polarization under different current densities.Additionally, the cathode current efficiency and quality of the zinc product in the ZnSO 4-MnSO 4-H 2 SO 4 electrolyte were also studied. The morphology of the anodic passive layer was ...
