The inhibitive effect of prop-2-en-1-one derivatives against C38 steel and its adsorption behavior were investigated in 1 M HCl solution utilized tafel polarization, (EIS) electrochemical impedance spectroscopy and (EFM) electrochemical frequency modulation method. The data obtain from protective efficiency rise with the improving the dose of inhibitor. The orders of %IE of prop-2-en-1-one derivatives are given: (1) >(2). The type of prop-2-en-1-one derivatives are mixed inhibitor whose adsorption habit onto C38 steel. EIS spectra exhibit one capacitive loop and confirm the protective ability. The surface morphology of inhibited C38 steel was analyzed by scanning electron microscope technology with energy dispersive X-ray spectroscopy ((SEM–EDX).
