| 摘 要： | 采用极化曲线、旋转圆盘电极试验和失重（质量损失）法研究了低合金钢在添加了H。o：的海水中腐蚀加速的主要影响因素。结果发现低合金钢在添加H2O2的海水中腐蚀加速主要受到了H2O2浓度、温度、搅拌速度和H2O2添加周期的影响。研究表明，搅拌速度不变、H2O2添加周期相同的条件下，在H2O2浓度为0．8mol／L的70℃海水中，低合金铜的腐蚀加速最显著；在试验的转速范围内，加速作用随搅拌速度增大变得更为显著；H2O2加入后350min内加速作用较明显。

| Abstract: | The main factors influencing the corrosion of low alloy steel by addingH2O2 into seawater was studied through potentiodynamic polarization curves, rotating disk electrode tests, and weight loss method. The results showed that the corrosion rate was the highest when H2O2was 0.8 mol/L and the solution temperature was 70 ℃. The acceleration effect turned remarkably while the stirring rate was enlarged. However, the acceleration effect was remarkable only in 350 min after adding H2O2into seawater. |
