The effect of some chalcone derivatives on the dissolution of carbon steel in 1.0 M HCl solution was studied using weight loss, potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation (EFM) techniques. The objective was to evaluate the inhibition efficiency of these derivatives, which was found to increase with the concentration of the inhibitors and decrease with rising temperature. The adsorption of chalcone derivatives on the carbon steel surface obeyed the Langmuir adsorption isotherm, indicating they act as mixed type inhibitors. Thermodynamic functions of the adsorption processes were calculated from weight loss data at different temperatures to analyze the inhibitor mechanism. Surface morphology of the carbon steel specimens was evaluated using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis. Results demonstrated the significant potential of chalcone derivatives as effective corrosion inhibitors in acidic environments, marking them as interesting candidates for practical industrial applications.
