The current density peak of brass welded line appeared at -0.012 V, and a porous corrosion film was formed. The electrode was passivated subsequently. The passivation film was made up of Cu2O, CuCl and ZnO. The passivation film dissolved with electrode potential, and displacement deposition took place between Cu and Zn. The copper redeposition on the electrode surface induced the increase of electrode activity and corrosion rate.
