Abstract
The effects of Cl−, NO3− and SO42− aggressive anions on the corrosion and passivation
behavior of carbon steel electrode in deaerated 0.50 M NaHCO3 solutions were studied
using potentiodynamic anodic polarization and SEM techniques. It was found that the
presence of Cl−, NO3− and SO42− anions stimulates the anodic dissolution rate in both the
active and the pre-passive potential regions. Moreover, significantly great effects were
observed in both the passive and the trans-passive potential regions. Pitting corrosion ...
