| Abstract: | 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. |
