摘要
通过1 a现场实验,并结合腐蚀形貌宏观观察、SEM、XRD及失重法对纯Cu和铜包钢在大港土壤环境中的腐蚀行为进行了研究。结果表明,现场埋样的纯Cu、电镀铜包钢和连铸铜包钢的平均腐蚀速率分别为1.01,1.05和1.07 g/(dm2·a),其中电镀铜包钢和连铸铜包钢的平均腐蚀速率接近,纯Cu的腐蚀速率略小;腐蚀特征均表现为非均匀的全面腐蚀,腐蚀程度有所差异;腐蚀产物均主要由Cu2O,Cu(OH)2和CuCl组成。
The corrosion behavior of pure copper and copper-clad steels in soil at Dagang district was investigated by burying test in nature field for one year with weight-loss measurement, as well as macro-morphology observation, characterization of corrosion products by SEM and XRD. The results showed that the corrosion rates for pure copper, electroplating copper-clad steel and continuous casting copper-clad steels are 1.01, 1.05 and 1.07 g/（dm2a）, respectively. The average corrosion rates of electroplating copper-clad steel and continuous casting copper-clad steel are roughly equal, and that of pure copper is slightly lower than copper-clad steels. Inhomogeneous general corrosion occurs mainly on the pure copper and copper-clad steels in soil at Dagang district, with the different corrosion degree. The corrosion products of pure copper and copper-clad steels consist of Cu2O, Cu（OH）2, CuCl.
