In this work, the effects of AC current density, electrolyte composition and AC current frequency on corrosion potential of Q235 steel were studied through simulation experiments, and the results are as follows: AC current makes corrosion potential of Q235 steel deviate positively or negatively depending on polarization rate of anode/cathode within different electrolytes, and the offset of corrosion potential becomes more significant as the AC current density increases or the AC current frequency decreases. Besides, the inherent mechanism of such offset induced by AC current was also studied through double layer model of interface and corrosion products analyses.
