Polarization behavior of Pb–Co powder-pressed alloy for electrowinning

Abstract

In this study, Pb–Co powder-pressed alloy was fabricated and used as a suitable anode material to replace Pb–Ca–Sn alloy in electrowinning.

Preparation and Electrochemical Properties of the CF-Ti/β-PbO2 Composite Anode for Zinc Electrowinning

“…7 Co and Sn can improve the compactness of the electrode surface active layer and the conductivity of the electrode. 8,9 The addition of Nd can improve the crystal surface energy, refine the grain, and increase the mechanical strength of the electrode and its surface density. 10 The purpose of any alloy addition is to refine the grain of the lead alloy, increase the mechanical strength and hardness of the lead plate, create a dense film of lead dioxide on its surface, and enhance the corrosion resistance of the alloy.…”
