不锈钢在硝酸冷凝物中的腐蚀比在液体中严重得多，甚至对非敏化钢也会导致晶间腐蚀。进行参数腐蚀测试是为了确定各种因素对此类腐蚀的影响。设计了特定的装置来控制和表征硝酸冷凝物。对铂电极和不锈钢电极上硝酸还原的电化学研究可以将腐蚀测试的结果与硝酸还原过程联系起来。 (C) 2000 Elsevier Science Ltd. 保留所有权利。
Corrosion of stainless steels in the presence of nitric acid condensates is far more severe than in the liquid bulk and can lead to intergranular attack even on non-sensitized steels. Parametric corrosion tests were performed in order to determine the effect of various factors on this type of corrosion. Specific apparatus was designed to control and characterize nitric condensates. An electrochemical study of the reduction of nitric acid on a platinum electrode and on a stainless steel electrode allows linking of the results of the corrosion tests to the process of reduction of nitric acid.
