概述了土壤中宏电池腐蚀的研究历程、现状、以及存在的问题,提出应用多种电化学测试技术研究影响土壤宏电池腐蚀的因素及条件;并指出,随着应用于地下的金属材料种类越来越多,地下金属构件多为异金属连接件,当异金属连接件经过土壤性质差异比较明显区段时,两种金属构件分别位于不同的土壤中,这种情况下就会有异金属接触腐蚀与土壤宏电池腐蚀的综合作用,因此,应该加强这方面的研究。 The research progress, status quo and existing problems of macrocell corrosion in soil were summarized. Several electrochemical test techniques were proposed to study the factors and conditions that affect the corrosion of macrocell battery. It is pointed out that with the application of underground metal materials More and more underground metal components are mostly dissimilar metal connectors, when the different metal connectors through the soil properties of the more obvious sections, the two kinds of metal components are located in different soil, in which case there will be different metal contact Corrosion and soil macro-cell corrosion combined effect, therefore, should be strengthened in this area.
