Corrosion Electrochemical Behavior Of Aluminum Flake Pigmented Water-Borne Epoxy Coating On Carbon Steel In Nacl Solution, Li-Li Xue, Li-Kun Xu, Qing-Fen Li, Hong-Qing Song, Wen-Juan Zhou, Guang-Zhang Chen
Journal of Electrochemistry
The corrosion electrochemical behavior of a water-borne epoxy coating pigmented with aluminum flake on carbon steel with artificial scratch defect was studied in 3.5% NaCl solution using electrochemical impedance spectroscopy(EIS)and scanning vibrating electrode technique(SVET).The results indicated that the defect presented anodic electroactivity at the initial stage of immersion,which extended gradually with time from the scratch into the neighboring coating,lowering the coating impedance.With further immersion,however,the electroactivity of the coating/steel interface decreased significantly due to the self-repairing of the corrosion products,causing an obvious increase of the coating impedance.In the later period of immersion,more scattered electroactive areas appeared under the coating because of …

Sn-SBA15 anode was prepared by composite electroplating.The first discharge and charge capacity was 1075mAh/g and 630mAh/g respectively.After fifty charge/discharge cycles,the charge and discharge capacity of Sn-SBA15 were retained above 400mAh/g.XRD patterns indicated that the Sn-SBA15 has tetragonal crystal type.SEM images showed that the Sn-SBA15 had a honeycombed surface.EIS results indicated that there was SEI film formed on the surface of Sn-SBA15 electrode.
