ABSTRACT Chemical corrosion inhibitors are highly effective in preventing metallic corrosion. However, due to environmental concerns and green chemistry principles for sustainable development, natural inhibitors such as plant extracts are increasingly preferred. These natural alternatives offer comparable efficiency while avoiding the extreme hazards associated with chemical inhibitors. This study looks at how well Hemigraphis colorata leaf extract (HCLE) inhibits the corrosion of mild steel (MS) in 0.5 M HCl. Standard electrochemical (EIS, PDP) and non‐electrochemical (weight loss) investigations were carried out in this procedure. Using FESEM analysis, the surface characterization of MS samples was observed both with and without HCLE. Gaussian 09 software was used for the computational study of active inhibitor compounds. Single‐point energy calculations and geometry optimization were done. The strength of the adsorption potential of phytochemicals on the iron (110) surface is portrayed in Monte Carlo simulations. This work demonstrates ethanolic extract of HCLE as a green, eco‐friendly corrosion inhibitor for mild steel using experimental, computational, and surface analyses.
