Novel Inhibitors for Corrosion Protection of Galvanized Steel

Abstract:

Nitrogen-containing heterocyclic dicationic compounds with antioxidant properties have been synthesized and characterized by NMR spectroscopy. Their corrosion inhibiting behavior for zinc and steel protection have been studied by electrochemical polarization methods to assess the potential suitability of those compounds in hybrid galvanic zinc protective coatings. The individual assessment for corrosion inhibiting activity will facilitate the shortlisting of eligible candidates, help to avoid potential incompatibilities of ingredients, and reduce times in the process of designing hybrid coatings for corrosion protection. This study has found that the compounds have significant corrosion protecting effect on steel and zinc and those molecules were shortlisted for our future studies on galvanic hybrid coating of steel.
