| 摘 要： | 采用电化学方法测量了不同pH值的SO4^2-、Cl^-、Ca^2 、Mg^2 、HCO3^-等离子对低碳钢腐蚀行为的影响。根据极化曲线及实验电位－pH图分析，指出pH值对低碳钢腐蚀行为具有相当的影响，Ca^2 、Mg^2 、HCO3^-等离子对低碳钢腐蚀具有抑制作用，Cl^-使低碳钢腐蚀加重。 |
| 关 键 词： | 低碳钢 腐蚀行为 油田注入水 矿化度 电化学测量 pH值 极化曲线 |

| Abstract: | The influence of the SO 4 2- ?Cl -?Ca 2 ?Mg 2 and HCO 3 - ions in solution of the different pH value to mild steel corrosion are measured with electrochemical method. It suggested that pH value has obvious influence to the corrosion of mild steel according to the measured polarization curves and experimental potential-pH graphs. And Ca 2 ?Mg 2 ?HCO 3 - have inhibiting effect to mild steel corrosion while Cl - enhances corrosion of the mild steel in the condition |
