摘　　要：建立了带锈铁器在海水介质中腐蚀的电化学模型:电化学反应在多孔腐蚀产物层的单个孔洞内发生,单个孔洞的阳极区对应着单孔的底部,单个孔洞的阴极区对应着单个孔壁上无数细小微孔内部。利用此模型研究了电化学交流阻抗图谱特征与多孔腐蚀产物层厚度之间的相关性,通过带锈铁器在海水介质中腐蚀的阻抗图谱分析验证了模型的正确性。Electrochemical model is proposed to describe the porous corrosion product of rusted iron artifacts in seawater.Electrochemical reactions occur inside the pores of the layer.The anodic surface corresponds to the end of the pores and the cathodic reaction occurs at the end of the micropores along the wall of the pores.The model is useful to study the relationship between characteristics of EIS and the porous rust layer.
