“…The semicircle's diameter grows as the concentration of L rises, indicating the creation of a more densely packed protective film on the AlSi alloys surface. [ 40–43 ] The inhibition activity of the prepared L on the corrosion behavior of AlSi alloys in 1 M HCl was investigated using polarization curves. Figure 10 shows the polarization curves for the prepared L at 298 K. Table 8 lists the polarization parameters, such as corrosion potential (E corr ) and corrosion current density (I corr ).…”

The condensation reaction between 5‐amino‐1,3,4‐thiadiazole‐2‐thiol and 1,2‐dibromoethane to afford the ligand L was carried out in direct to obtain the desired organic ligand. New [Er(L)ClH2O]Cl2·3H2O, [Yb(L)(H2O)2]Cl3·4H2O, and [Ta(L)Cl2]Cl3·4H2O complexes have been prepared from (L) by reacting one mole from metal ions with one mole from L. In addition to their physical characteristics, they were described using spectroscopic techniques (infrared [IR], nuclear magnetic resonance [NMR], and UV–Vis), gas chromatography (GC)‐mass, and X‐ray powder diffraction. Further interpretation of complex structures was supported by measurements of molar conductivity, magnetic susceptibility, mole ratio, and thermodynamic investigations in addition to theoretical study through the use of density functional theory and characterization techniques. IR spectral data showed the mode of action of the neutral tetradentate L ligand and its coordination via two N‐amine and two S‐thiols. The octahedral geometry surrounding the central lanthanide ions was suggested by the magnetic moments, diffused reflectance, and spectral data. Molar conductivity results exposed that Yb(III) and Ta(V) chelates were 1:3 electrolytes and Er(III) chelate was 1:2 electrolyte. In addition, practically all the complexes demonstrated effective antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus species, via inhibition zone diameters in 9–15 mm mg−1 range. However, neither Candida albicans nor Aspergillus flavus species were susceptible to their antifungal effects. Finally, molecular docking (MOE) experiments showed the significant binding affinity of the ligand and its complexes with several 6KOC, 6LU4, and 6LU4 protein receptors. Finally, it is important to emphasize that these complexes may be potential antioxidant agents according to the biochemical results. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) methods were accustomed to examine the corrosion inhibition of aluminum silicon alloys (AlSi) in 1 M HCl solution. Experimental measurements indicate that the thiadiazole ligand reduces the corrosion rate.

“…For the development of environmentally benign potential inhibitors along with an understanding of the inhibition mechanism, heterocyclic compounds have been considered a great alternative to replace the toxic inorganic corrosion inhibitors. ,− Recently, researchers have concentrated more on imidazole-based compounds due to their simple structure and very high adsorption affinity with carbon steel and copper metal in acid as well as in alkaline media, resulting in effective corrosion inhibition at a low inhibitor dose. − Curkovic et al found that the imidazole compound exhibited better adsorption in an alkaline medium compared to an acidic medium . Recently, our research group disclosed that the phenyl and methionine amino acids derived from imidazolium zwitterions showed pronounced corrosion inhibition performance compared to other similar inhibitors. , In the continuous study, in the present work, three sodium L-2-(1-imidazolyl) alkanoic acids (IZSs) have been selected as corrosion inhibitors for mild steel corrosion in a seawater environment.…”

Three novel natural amino acid-derived sodium L-2-(1-imidazolyl) alkanoic acids (IZSs), namely, sodium 2-(1Himidazol-1-yl)-4-methylpentanoate (IZS-L), sodium 2-(1H-imidazol-1-yl)-3-phenylpropanoate (IZS-P), and sodium 2-(1H-imidazol-1-yl)-4-(methylthio)butanoate (IZS-M), were investigated as corrosion inhibitors. The IZSs were synthesized following the green chemistry principles, and their structure was characterized using FTIR and NMR techniques. The corrosion study results reveal that a moderate concentration of IZSs (having low solution conductivity) showed potential corrosion inhibition for mild steel in artificial seawater. At longer immersion, IZS-P forms a uniform protective film and exhibits the potential inhibition efficiency of 82.46% at 8.4 mmol L −1 . Tafel polarization results reveal that IZS-P and IZS-M act as mixed types with an anodic predominantly corrosion inhibitor. The electrochemical impedance spectroscopy results signify that IZSs inhibit mild steel corrosion through the formation of an inhibitor film on the metal surface, which was further confirmed by the FTIR, SEM, EDX, and XPS studies. DFT result shows that in IZS-P, the benzylic group (−CH 2 −Ph) has greater electron distribution compared to isobutyl (−CH 2 CH(CH 3 ) 2 ) in IZS-L and methythioethyl group (−CH 2 CH 2 SCH 3 ) which supported the corrosion inhibition performance at longer immersion [IZS-P (82.46%) > IZS-M (67.19%) > IZS-L (24.77%)].

“…Basically, benzohydrazide and derivatives find wide applications in the biological field making them a potential group of organic compounds [9]. The chemistry of the -C=N-group takes an important role in the inhibition process due to the presence of a double bond and lone pair of electrons on the nitrogen atom in the same moiety [10][11][12].…”

This research investigates the effect of Schiff base, namely, N'-[4-(dimethylamino) benzylidene]-4-hydroxybenzohydrazide (SB) on the corrosion mitigation of mild steel (MS) in hydrochloric acid medium (HCl) using potentiodynamic polarization (PDP) technique. The study highlights the effect of SB concentration, HCl concentration, and temperature on the corrosion current density (icorr) and inhibition efficiency (IE). The adsorption of SB onto the MS surface was justified with the support of kinetic and thermodynamic parameters. The morphological behavior of the MS surface was analyzed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). A blend of statistical study and interaction plots has been applied to obtain a thorough understanding of the corrosion parameters. Experimental results obtained by PDP measurements revealed that tested compounds had a good anti-corrosion capacity. The main and interaction effects of the parameters on the response were analyzed using Box-Behnken Design. An empirical model equation from experimental results elucidates the relationship among the variables. The optimized parameters for the maximum output were recognized. The maximum IE of 81.5 was predicted by RSM with temperature (A = 30 °C), HCl concentration (B = 0.5 M), and Inhibitor concentration (C = 0.0001 M). Using RSM, further analyses regarding individual and interaction effects between the variables can be more comprehensive. Few more parameters such as pH and time can be included in the future study.
