Abstract利用气体腐蚀试验箱、红外光谱和扫描电镜研究了铝在含SO2的湿润气氛-不含SO2的干燥气氛循环的加速试验条件下的腐蚀规律。并进行了未加SO2而其它试验条件相同的对比试验。试验共分别进行5个周期(120h)。随着时间延长,SO2的腐蚀性作用明显加强,铝的腐蚀表现出正指数变化规律,即铝的腐蚀速率随时间延长不断增加。结果还显示出铝在含SO2的潮湿环境中很难形成保护性好的Al2O3膜,铝在此试验环境中的腐蚀产物为Al2(SO4)3·18H2O。在未加SO2的对比试验环境中铝的腐蚀轻微,5个周期累计质量增加仅为0.043g/m^2,腐蚀质量损失明显小于加SO2时的腐蚀质量损失;试样表面仍很光亮。
