摘　　要：常用的金属接地材料有热镀锌钢、铜、不锈钢、铜包钢、不锈钢包钢等。本文运用电化学工作站对这5种接地材料在5种土壤模拟液中进行动电位扫描,得到的极化曲线经过分析、Tafel拟合,结果表明,不锈钢包钢在5种土壤模拟液中不仅有稳定的耐蚀性,且耐蚀性要优于热镀锌钢、铜和铜包钢。Now commonly used metal grounding materials are hot-dip galvanized steel,copper,stainless steel,copper-clad steel and steel-clad steel.In this paper,the polarization curves obtained by scanning the action potential of these five grounding materials in five kinds of soil simulated solutions are analyzed and fitted by Tafel according to the using of electrochemical work station.The results of analysis and Tafel fitting show that the corrosion resistance of stainless steel in five simulated soil solutions is better than that of hot-dip galvanized steel,copper and copper-clad steel.
