The synergistic inhibition effect of N‐(furan‐2‐ylmethyl)‐7H‐purin‐6‐amine (FYPA) and iodide ion on mild steel corrosion in 1 mol/L HCl was investigated using weight‐loss tests, electrochemical techniques, and surface analysis. The experiments revealed that the FYPA + KI mixture was a temperature‐dependent inhibitor, which strongly inhibited the corrosion of mild steel compared with FYPA. Based on electrochemical results, FYPA and FYPA + KI behaved as mixed‐type inhibitors, and their inhibition efficiencies were 73.66% and 96.01%, respectively. The calculated synergistic parameter value was larger than unity, illustrating that enhancement of inhibition in the presence of KI could be a result of synergistic action. Surface analysis techniques (scanning electron microscope/scanning electrochemical microscope) confirmed the presence of additives on the studied mild steel surface. A plausible mechanism of corrosion inhibition was proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
