“…[15] Consequently, Schiff bases have emerged as promising candidates for corrosion inhibitors due to their excellent adsorption and film-forming properties in recent years. [16][17][18][19][20][21][22][23][24][25] In particular, several Schiff bases have been identified as effective corrosion inhibitors for mild steel, [26][27][28][29][30][31][32] aluminum, [33,34] and copper [35,36] in media containing HCl [26,37] and H 2 SO 4 . [30,31] For example recently Betti et al investigated the corrosion protection of a novel Schiff base, 3-((5-mercapto-1,3,4-thiadiazol-2-yl) imino)indolin-2-one (MTIO), and achieved 96.9 % inhibition efficiency for mild steel in HCl solution.…”

The inhibition power of two Schiff bases on carbon steel corrosion in 1 M HCl and 0.5 M H2SO4 solutions has been investigated using weight loss, Tafel polarization, and electrochemical impedance spectroscopy techniques. The results revealed that increasing the concentration of inhibitors in acidic solutions led to a higher inhibition efficiency. The polarization curves indicated that the Schiff bases acted as mixed inhibitors, affecting both the cathodic and anodic reactions. The adsorption of the inhibitors on the carbon steel surface followed the Langmuir adsorption isotherm, and various adsorption isotherm parameters such as Kads, ΔGads, ΔHads, and ΔSads were determined at room temperature. Furthermore, the effect of temperature on the inhibitors′ performance was examined within the range of 25–45 °C. The corrosion‐related activation energy, pre‐exponential factor (k), activation enthalpy, and entropy were calculated to assess the inhibitors′ behavior. Scanning electron microscopy (SEM) was employed to examine some carbon steel samples, revealing differences in inhibition efficiency attributed to the inhibitors′ chemical structure. The results highlighted the highest inhibition efficiency in H2SO4 medium at 93.4 %, with a corresponding free energy of 39.51 KJ/mol indicating physical‐chemical adsorption of inhibitor molecules. Furthermore, an enthalpy value of −40.6 KJ/mol suggested an exothermic inhibitor absorption process. The findings are presented and discussed in detail.

Background: Imidazoline derivatives were widely used in the field of metal corrosion protection due to the low toxicity and excellent corrosion inhibition performance. In order to further reduce synthesis costs and improve corrosion inhibition performance, oleic acid, diethylenetriamine, and anisaldehyde were used as raw materials to synthesize imidazole Schiff corrosion inhibitors (HM), and the corrosion inhibition mechanism on Q235 in 1.0 mol/L HCl solution was studied rigorously. Method: The corrosion inhibition ability was verified using weight loss and electrochemical experiments. Scanning electron microscope (SEM), energy dispersive spectrometer (EDS), and X‐ray photoelectron spectroscopy (XPS) were used to detect and analyze the protective film formed on the surface of Q235 after weight loss. Density functional theory (DFT) demonstrated the adsorption sites and reaction activity of the corrosion inhibitor, Molecular Dynamics (MD) further validated the corrosion inhibition mechanism. Significant Findings: Imidazoline corrosion inhibitor could form a stable protective film on the surface of Q235. With the concentration increased of HM, the corrosion inhibition efficiency increased gradually, and with the temperature increased, the corrosion inhibition efficiency decreased gradually. At the optimal concentration, the corrosion inhibition rate could reach 98.98%. HM belonged to a mixed type corrosion inhibitor that mainly suppresses the cathode and could spontaneously adsorb on the metal surface, following the Langmuir isotherm for adsorption.
