| 摘 要： | 目的快速研究大气环境对钢制输电铁塔腐蚀的影响。方法采用室内加速腐蚀实验,研究碳钢试样在湿度和SO2浓度不同的气氛中的腐蚀行为。结果用极化曲线法测得的金属腐蚀速率与失重法测得的结果具有很高的一致性。相对湿度较低时,改变腐蚀性气体的浓度,对碳钢的腐蚀影响不显著;碳钢在高湿度的含SO2气氛中会发生严重腐蚀。结论降低湿度是防止或减缓碳钢在含SO2气氛中腐蚀的有效途径。

| Abstract: | Objective To study the influence of atmospheric environment on steel transmission tower. Methods The corrosion behavior of carbon steel in different concentration of SO2 and different relative humidity was investigated using accelerated corrosion test. Results Severe corrosion occurred for carbon steel in SO2 environment with high relative humidity. Oxygen corrosion was the main corrosion type. The corrosion rate of carbon steel was greatly reduced in a low relative humidity environment. As the SO2 concentration increased, the corrosion rate did not significantly increase. Conclusion Reducing relative humidity could effectively prevent or slow down the corrosion of carbon steel in SO2 environment. |
