Abstract Scope The corrosion behavior of mild steel in 1.0 M HCl by 4-nitrophenyl-3-thiosemicarbazide (TSC-NO2) has been studied with electrochemical methods and quantum chemical methods. The electrochemical tests show that the polarization resistance of MS increasing the presence of inhibitors in acid solution. Potentiodynamic polarization studies reveal that this molecule act as an efficient mixed type inhibitor. The associated activation energy of corrosion has been determined. The adsorption of these inhibitors on the mild steel surface in acidic medium obeys the Langmuir absorption isotherm. The surface morphologies of the MS were analyzed with scanning electron microscope at 120 h exposure period by scanning electron microscopy (SEM). The density functional theory (DFT) at the B3LYP functional with the 6-311 G(d,p) basis set were performed for compound. Keywords: Thiosemicarbazide, Mild Steel; EIS; Acid Corrosion; Density Functional Theory
