Résumé : |
In this study, zinc aluminum hydrotalcite intercalated with 2-benzothiazolylthio-succinic acid (BTSA) as a container of corrosion inhibitor was prepared and incorporated in an epoxy coating. The HT-BTSA obtained was characterized using infrared spectroscopy and X-ray diffraction. BTSA release from HT-BTSA in 0.5 M NaCl solution was investigated using UV–Vis spectroscopy. The corrosion protection performance of the epoxy coating containing HT-BTSA was evaluated and compared to the pure epoxy coating and the epoxy coating containing HT by cathodic disbonding test, electrochemical impedance spectroscopy, salt spray test, and adhesion measurement. It was shown that the BTSA was intercalated in hydrotalcite and its loading was about 33.5%. The BTSA release from HT-BTSA increased with the pH of the NaCl solution. It was also shown that the presence of HT or HT-BTSA in epoxy coating improved the resistance to cathodic disbonding and the adhesion of the epoxy coating. Corrosion protection performance of epoxy coating containing HT-BTSA was higher than that of epoxy coating containing HT. |
