| 英文摘要 | The present work focused on investigating the corrosion behavior of NiCu low alloy steel in 0.05 M NaHCO3 solutions with different Cl- concentrations under the aerobic-anoxic condition. The results showed that NiCu steel tended to be pseudo-passivated in the solutions of 0.05 M NaHCO3 and 0.05 M NaHCO3 + 0.01 M NaCl exposed to air. The cathodic process transformed from oxygen reduction to the common reduction of oxygen and alpha-FeOOH, while the anodic process was the iron dissolution. As Cl- increased to 0.1 M, the steel tended to be activity dissolution. Due to the blocking effect of rust layer on the oxygen, the cathodic process transformed to the reduction of alpha-FeOOH. After the solutions were deoxidized, the cathodic process was controlled by only rust reduction. Meanwhile, both the cathodic process and anodic process of NiCu steel corrosion were significantly inhibited. During the whole aerobic-anoxic immersion, the corrosion rate of NiCu steel increased with Cl- concentration. It was not only related to the promotion of Cl- on the anodic dissolution of steel, but also related to the cathodic reduction of more alpha-FeOOH generated, which could accelerate the cathodic process. |
