摘　　要：采用电动位极化法、电化学阻抗谱技术、失重法和扫描电子显微镜研究了Q235碳素钢和含钛耐候钢在大气环境和雨水中的腐蚀现象。结果表明:随着在雨水溶液中浸泡时间的增加,碳素钢和耐候钢的阻抗都是先增大,到达极值后减小。电化学阻抗谱的膜值结果可以比较2种材料的耐蚀性,雨水溶液中含钛耐候钢的耐蚀性优于Q235碳素钢。通过曝晒1周期(年)的实验结果说明含钛耐候钢的腐蚀等级为C2;Q235碳素钢的腐蚀等级为C3,分别属于低等和中等。在大气环境中含钛耐候钢的腐蚀性能大于Q235碳素钢。The corrosion phenomena of Q235 carbon steel and titanium-containing weathering steel steels in atmospheric conditions and rainwater have been studied using electrokinetic potential polarisation,electrochemical impedance spectroscopy techniques,loss-in-weight methods and scanning electron microscopy.The experimental results show that the impedance of both carbon and weathering steels increases with increasing immersion time in rainwater solutions and decreases after reaching extreme values.The results of the film values of the electrochemical impedance spectra allow a comparison of the corrosion resistance of the two materials,with the corrosion resistance of the titanium-containing weathering steel in rainwater solution being better than that of the Q235 carbon steel.The experimental results from the 1a cycle of exposure indicate a corrosion rating of C2 for the titanium-containing weathering steel and C3 for the Q235 steel,which are low and medium respectively.The corrosion performance of the titanium-containing weathering steel is greater than that of the Q235 carbon steel in atmospheric conditions.
