Fig.13. Equivalent circuit used for describing the corrosion of exposed carbon steel samples (R1—the resistance of electrolyte, Q—the capacitance of corrosion product, R2—the charge transfer resistance in corroded area, W—Warburg diffusion impedance, C—the double layer capacitance, R3—the charge transfer resistance in substrate area)
