Materials and Corrosion, EarlyView.Electrochemical impedance spectroscopy (EIS) monitored corrosion on mild steel under cathodic protection in soil‐like conditions. CP reduced corrosion from 410 to 7 µm/yr, shifting the mechanism from mixed activation–diffusion to activation‐controlled, enabling protective calcareous and oxide film formation.
