The resistance to deterioration ability of an inhibitor, primarily 2-(benzylidene-amino)- benzenethiol, which influences the deterioration of mild steel dished in sea water was studied using a mass loss approach, an electrochemical study, in addition to AC impedance spectra. This was done in order to determine how an inhibitor influences the deterioration of mild steel dished in sea water. AFM, FTIR, SEM, and EDAX are all employed to understand the essence of the surface morphology. According to the magnitudes of the mass loss methodology spectacle, the presence of 250 ppm of the inhibitor in seawater has an inhibition efficiency (IE) of 82.37 percent. Polarization is an examination of abilities that demonstrate that strategy, such as cathodic inhibitors. The incredulous cover rising can be seen on the AC impedance spectrum of the mild steel. The fact that the protective coating has a chemical with the formula Fe2+ -inhibitor has been confirmed by FTIR, SEM, EDAX, and AFM.
