摘要	The effect of HCO3- and Cl- on the corrosion behavior of Q345 carbon steel in soil simulated solutions was investigated through electrochemical and surface characterizations. The results show that the sample behaves with active dissolution state in low concentration of Cl- solution while pseudo passivation of sample is observed in high concentration of Clsolution. However, in solutions containing low concentration of HCO3-, the addition of high concentration Cl- does not result in the pseudo passivation of sample due to the formation of discontinuous film, which increases the corrosion rate. In addition, in solution containing high concentration of HCO3-, the addition of high concentration Cl- leads to much higher increase of corrosion rate. The deep corrosion pit is observed on the matrix due to the rapid rupture of FeCO3 film and the sufficient development of pitting.(c) 2022 The Author(s). Published by Elsevier B.V.
