摘要：

In this study, zinc or cerium exchanged zeolite was introduced to develop a novel anti-corrosion pigment. The primer paint was made using them and was coated on galvanized(GI) steel. The anti-corrosion performance was measured using electrochemical impedance spectroscopy(EIS). And scanning vibrating electrode technique(SVET) was employed to observe the cut-edge corrosion process of the coated GI steel. From EIS and SVET results, it could be confirmed that Ce ion-exchanged zeolite showed the anti-corrosion performance higher than Shieldex C303 and Zn ion-exchanged zeolite. Finally, it was found that metal ion-exchanged zeolite may provide new possibility as the smart cathodic corrosion inhibitor delivery systems on galvanized steels.
