Corrosion Behavior of Zn and Cu as Grounding Material in Shanbei Soil Solution

Article Preview

Abstract:

The corrosion behavior of typical grounding materials Zn and Cu in Shanbei soil solution was studied by immersion test technique, galvanic corrosion current measurement and simulated stray current test. The results showed that Zn was seriously corroded with the corrosion product of ZnCO₃, while Cu was slightly corroded with the main rust of Cu₂(OH)₂CO₃ and copper oxides. The corrosion of Zn was accelerated and Cu was protected when coupled them together. Stray current can significantly increase the corrosion process of both Zn and Cu.
