摘要/Abstract

摘要： 采用阳极极化曲线、循环伏安法、交流阻抗法、XRD和SEM等技术手段研究了银含量对铝基铅银合金电化学性能的影响。结果表明，在硫酸电解液中，随着银含量的增加，合金的耐腐蚀性逐渐提高，腐蚀膜的阻抗和析氧过电位逐渐降低。

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
