Abstract: Lead-silver anodes with different contents of silver were prepared on the surface of Al substrates by electrodeposition. The impact of the silver concentration on the electrochemical properties of electrodeposited lead-silver alloys was investigated by the anodic polarization curves, cyclic voltammetry, EIS, XRD and SEM. The results show that the increase of silver contents to the lead-silver anodes can enhance the corrosion resistance and decrease the impedance of the corrosion film and oxygen overpotential.

Key words: electrodeposited lead-silver alloy, electrochemical, anode, corrosion-resistance behavior
