摘要: 本工作采用探头式电解槽,对涂装了醇酸漆和电泳漆的A3钢片,进行了交流阻抗频谱测定,给出了评选结果,同时显示了采用双探头电解槽在评选测定应用中的优越性。

Abstract：The experimental approach for carrying out electrochemical impedance measuremerits for coated metals using probe cells is described. Equivalent circuit for the dualprobe cell is given, and the experimental impedance diagrams are discussed in terms ofcoating and interface properties and their changes during exposure to corrosive environmerits. The systems studied include alkyd coating and electrophoretic paints with or without inhibitor added. It is found that the potential difference △E_se for dual-probe cell taken each time before making impedance measurement has good correlation with the deterioration degree of the coating measured hereafter.
