Correlation between electrochemical impedance and current distribution of carbon steel under organic coating / D. Kong in Materials and corrosion, Vol. 63 N° 6 (Juin 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 6 (Juin 2012) . - pp. 475–480 Titre : Correlation between electrochemical impedance and current distribution of carbon steel under organic coating Type de document : texte imprimé Auteurs : D. Kong, Auteur ; Y. Wang, Auteur ; W. Zhang, Auteur Année de publication : 2012 Article en page(s) : pp. 475–480 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Current  distribution;  EIS;  organic  coating;  wire  beam  electrode Résumé : The current distribution of carbon steel beneath intact organic coating exposed to 3.5% NaCl solution was investigated by the wire beam electrode (WBE) method. The electrochemical impedance spectroscopy (EIS) of individual electrodes with high current was characterized to analyze the behavior of the coating degradation and metal corrosion at coating/metal interface. The polarity switch of the electrode under the coating was observed. The mechanism of coating degradation and carbon steel substrate corrosion was discussed from a point of electrochemical distribution.
