Passivation and Pitting Corrosion Behavior of a Novel Alloy Steel (00Cr10MoV) in Simulated Concrete Pore Solution
In order to prolong the service life of reinforced concrete structures in a severe marine environment, a novel alloy steel (00Cr10MoV) was developed. The passivation behavior of 00Cr10MoV steel in a simulated concrete pore solution (SCPS) was studied by electrochemical impedance spectroscopy (EIS). Furthermore, the influence of chloride concentrations and passive film on the pitting corrosion resistance of 00Cr10MoV steel was investigated using cyclic potentiodynamic polarization (CPP) and scanning electron microscopy (SEM)/energy dispersive X-ray spectroscopy (EDS). For comparison, conventional low-carbon steel (20MnSiV) and 2304 duplex stainless steel were also investigated. The results indicate that the pitting corrosion resistance of passivated 00Cr10MoV steel is significantly higher than that of passivated 20MnSiV steel. The formation of a protective passive film and the generation of dense Cr-bearing corrosion products of 00Cr10MoV steel are responsible for its high pitting corrosion resistance.
