Influence of Sn and Zn Elements on Corrosion Behavior of Copper

    Graphical Abstract
    • Abstract
  • The deoxidization electric current method was adopted to determine the influence of Sn and Zn elements on the corrosion behavior of copper in the weak acid(pH=6) and weak basic(pH=8) solutions.The results showed that a compact and stable protective film was formed on the surface of the copper alloy with 5% Sn in the weak acid solution,which improved the corrosive resistance of copper,while in the weak basic solution,the effect of both Sn and Zn was negligible.
