Abstract The electrochemical corrosion behavior of the seawater corrosion resistant rebar steel 00Cr10MoV and the formed passive films on this rebar in simulated concrete pore solutions were examined by means of electrochemical impedance spectroscopy (EIS), polarization curves and X-ray photoelectron spectroscopy (XPS). While the effect of Cl- in solutions on the formation of passive films was also investigated. The results show that passive films formed on the 00Cr10MoV steel in simulated concrete pore solutions were composed of FeO, Cr2O3, γ-FeOOH and CrOOH. The Cl- prevented the formation of passive films on the steel, and thereby resulted in decrease of pitting potential and charge-transfer resistance, but in little impact on the passive current density. The passive films formed on the steel after immersion in artificial solutions for 240 h exhibited excellent corrosion resistance to Cl- solutions, which could maintain a large charge-transfer resistance of 2.755×106 Ωcm2 in solutions with Cl- concentration as high as 5 mol/L. In general, the 00Cr10MoV steel exhibited resistance to Cl- attack superior to 20MnSiV steel.
