The anticorrosion performance of ethanolic extract of propolis (EEP) on SAE 1010 carbon steel specimens dipped in 3.5% NaCl was evaluated by advanced electrochemical and surface morphological assessments. The adsorption of EEP on the surface of the specimens investigated was delineated by an optical profilometer (OP), atomic force microscopy (AFM), and scanning electron microscopy (SEM) before and after immersion in aqueous solution of 3.5% NaCl. The electrochemical feedback assisted by PDP, EIS, and DEIS of the inhibited electrodes was compared with that of the uninhibited electrodes, and EEP's role in the formation of a protective barrier was identified. All the qualitative and quantitative data thus obtained establish EEP as a potential inhibitor for the SAE 1010 carbon steel corrosion in NaCl solution.
