Abstract  

In this work, the pitting corrosion behavior of Cu in the mixed solution of HCO3-, Cl- and SO42- simulating groundwater was investigated by means of cyclic polarization test and SEM microscopy. The results showed that both SO42- and Cl- can synergistically promote the anodic dissolution of Cu electrode. Cl- can decrease the corrosion potential of Cu to enhance its electrochemical activity. The plot of pitting sensitivity of Cu showed that the pitting critical concentration of Cl- was 0.02 mol/L. When the concentration of Cl- was low, SO42- did not affect the pitting susceptibility; when the concentration of Cl- was in the middle, SO42- strongly inhibited the pitting corrosion of Cu; when the concentration of Cl- was high, the pitting susceptibility will first increase and then reduce with increasing the concentration of SO42-. Regardless of what concentration of SO42-, Cl- can promote the pitting corrosion of Cu. In the current solution system, it is found that the pitting corrosion of Cu was sorely sensitive to SO42- and Cl-.
