摘要
对埋藏在三峡土壤腐蚀试验站已33年的2种低碳钢材料进行了分析。结果表明,试件以局部腐蚀为主要特征。腐蚀产物主要由FeO(OH)、FeCO3、Fe2O3、Fe3O4及铁的硫化物和一些铁盐所组成。焊缝及钢中的夹杂导致局部腐蚀的发生。
Analyses and measurements for two kinds of mild steel buried in a station at the site of Three Gorges by Chang Jiang River for 33 years were made. The results indicated that these samples had the characteristics of local corrosion. Local corrosion ocurred in welding seam and metallurgical defects. Corrosion products consisted of FeO(OH), FeCO 3, Fe 3O 4, Fe 2O 3 and some irons salts.
