【摘要】 采用循环伏安法研究了铜上电沉积铅锡合金和铸造的铅合金在硫酸中的电化学行为,并且在多次循环后,比较两种电极的循环伏安曲线及表面形貌.结果表明:在硫酸电解液中,铜上电沉积铅锡合金电极表面发生的主要电化学反应,与铸造铅电极表面发生的主要的电化学反应基本相同,多次循环后电沉积铅锡合金电极具有更加均匀的表面形貌和组织结构.更多还原

【Abstract】 To study the electrochemical performances of lead foam electrode prepared from electrodeposited lead alloy on copper foam substrate and electrodeposited lead alloy electrode, cyclic voltammogram ( CV) method was used. After several cycles, the CV curves and surface morphology of two electrodes were compared. Results show that in sulfuric acid the main electrochemical reactions on electrodeposited lead-tin alloy are about the same as that on cast lead alloy, and after several cycles the electrodeposited lead-tin alloy e-lectrode possess more uniform surface morphology and structure.更多还原
