Abstract

This study demonstrates the influence of ceramic nanocontainers loaded with corrosion inhibitor 2-mercaptobenzothiazole into hybrid organic–inorganic coatings on the corrosion protection of hot dip galvanized steel. The corrosion resistance of these coatings was evaluated using electrochemical impedance spectroscopy and the results disclosed that the coating including 4% w/w of loaded nanocontainers presented the highest total impedance values until the end of immersion time. On the other hand, the coating without nanocontainers and the coating including 10% w/w of loaded nanocontainers revealed self-healing properties. The mechanical integrity of the coatings is also addressed through nanoindentation and nanoscratch techniques.
