英文摘要The purpose of this research is to investigate the influence of SO42- in aerobic/anaerobic environment and its interaction with HCO3- on the corrosion behavior of Q345 carbon steel using potentiodynamic polarization, X-ray diffraction, white-light interferometer, electrochemical impedance spectroscopy and scanning electron microscopy methods. It was found that the corrosion rates of Q345 carbon steel are faster in aerobic environment under the synergistic effects of SO42- and dissolved oxygen compared to that in the absence of oxygen. In solutions containing SO42- and HCO3- in anaerobic environment, a high proportion of HCO3-/SO42- leads to the passivation of Q345 carbon steel sample as a result of the competitive adsorption of HCO3- on substrate surface with smaller radius. As the ratio of HCO3-/SO42- decreases, the presence of SO42- can enhance the dissolution of Fe matrix, thereby resulting in the corrosion of specimens. High concentration of HCO3- also exhibits the suppression on corrosion because of the formation of dense corrosion products.
