研究了电连接的20无缝钢管试件在穿过两种相邻但理化性质迥然不同的土壤时的腐蚀行为,在粘土中部分表现为阳极,有较严重的腐蚀,在沙土中部分表现为阴极,腐蚀较轻。
The corrosion behaviors of 20 seamless steel tubes with electrical connection were investigated when they passed through two adjacent but very different physical and chemical properties of soil. Some of them behaved as anodes in the clay and had more serious corrosion. In the sand, Cathode, less corrosion.
