“… 13,14 For instance, El Belghiti et al showed that two 3,5-bis (disubstituted)-4-amino-1,2,4-triazole derivatives (T1 and T2) have a corrosion inhibition efficiency of 86% for mild steel when used at a concentration of 1.0 × 10 −3 M in 2 M H 3 PO 4 . 15 More recently, newly synthesized heterocycles, namely (1- p -tolyl-1 H -1,2,3-triazol-4-yl) methanol (TTM) 16 and 5-hexylsulfanyl-1,2,4-triazole (HST), 17 have been investigated in inhibiting steel corrosion in 1.0 M HCl. These compounds displayed excellent inhibition performance.…”

“…As shown in Table 1 , most of the tested heterocyclic organic compounds have significant inhibitory efficacy. PMBMH has the strongest inhibitory ability of the heterocyclic organic compounds reported in Table 1 [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ], with a performance equivalent to those reported in [ 15 , 23 , 26 , 28 ]. As the concentration of PMBMH increases, the rate of corrosion decreases, and the inhibitive efficacy improves.…”

Using traditional weight-loss tests, as well as different electrochemical techniques (potentiodynamic polarization and electrochemical impedance spectroscopy), we investigated the corrosion-inhibition performance of 2,2′-(1,4-phenylenebis(methanylylidene)) bis(N-(3-methoxyphenyl) hydrazinecarbothioamide) (PMBMH) as an inhibitor for mild steel in a 1 M hydrochloric acid solution. The maximum protection efficacy of 0.0005 M of PMBMH was 95%. Due to the creation of a protective adsorption layer instead of the adsorbed H2O molecules and acidic chloride ions, the existence of the investigated inhibitor reduced the corrosion rate and increased the inhibitory efficacy. The inhibition efficiency increased as the inhibitor concentration increased, but it decreased as the temperature increased. The PMBMH adsorption mode followed the Langmuir adsorption isotherm, with high adsorption-inhibition activity. Furthermore, the value of the indicated that PMBMH contributed to the physical and chemical adsorption onto the mild-steel surface. Moreover, density functional theory (DFT) helped in the calculation of the quantum chemical parameters for finding the correlation between the inhibition activity and the molecular structure. The experimental and theoretical findings in this investigation are in good agreement.

“…This would also suggest that the inhibitors were successfully adsorbed onto the surface of the MS demonstrated by the charge transfer resistance value in the C dl formula (equation 5). Similarly, R ct values would also account for diffusion layer resistance, film resistance, and polarization resistance; denoting for the accumulation of corrosive products over the surface [34]. Based on the values in Table 3, all double-layer capacitance values of the inhibitors proved to be lower than that of the blank, suggesting the adsorption of the inhibitor molecules onto the surface of the MS samples.…”

The corrosion inhibition property of selected small organic compounds was investigated using electrochemical measurements, including potentiodynamic polarization (PDP), linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), and density functional theory (DFT) calculations. The inhibition efficiency (IE %) of the inhibitor on mild steel (MS) in 1 M HCl was then determined. Results show that the presence of the inhibitors resulted in decreased corrosion current density (I corr ) values and increased polarization resistance (R p ). Furthermore, the use of higher concentrations of inhibitors led to an increased inhibition efficiency. Tafel slopes and shifts in the E corr values suggested that the inhibitors tested are mixed-type inhibitors that form a protective layer on the surface of the substrate. Of the organic compound inhibitors tested, the inhibitor 4-ethylpyridine (EP) exhibited the highest R p values and inhibition efficiency values from the PDP, LPR, and EIS analyses, respectively. DFT calculations showed negative adsorption energies and confirmed the chemisorption of the inhibitors allowing for the formation of a hydrophobic protective film against corrosion and correlations between the quantum chemical values and electrochemical data were demonstrated. The results show the influence of the presence of electronegative O, S, and N atoms, as well as the role of aromatic rings in the promotion of surface protection by preventing aggressive ionic species from binding onto MS.
