摘要

Abstract

The potential dependence of the faradiac impedance of carbon steels in 3.5% NaCl solution was measured by ac impedance technique. The polarization resistance

and also the cathodic protection efficiency obtained from weight loss

maximized at 0.70 V with respect to saturated Ag/AgCl electrode. Consequently

the potential at faradaic impedance maximum corresponds well to the optimum cathodic protection potential. The study results showed that the ac impedance technique is a promising method for monitoring and determining the optimum cathodic protection potential.
