“…In order to understand the structural analysis of the metal surface, morphological images were taken by three different methods. Metal microscopy ( Figure 10) [60], FE-SEM at 200 times magnification ( Figure 11) [61] and AFM images (Figure 12 and Figure 13) [62] were evaluated. All morphologies were realized in 1.0 M HCl solutions with and without 1.0×10 -4 M DMT at a temperature of 298 K and an immersion time of 120 hours.…”

The Inhibitor Effect of (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc(II) Chloride, an Industrial Cationic Azo Dye, onto Reducing Acidic Corrosion Rate of Mild Steel

This study covers the stages of testing whether the azo dye with chemical name (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc (II) chloride (DMT), known as Maxilon Red GRL in the dye industry, can be used as an anticorrosive feasible inhibitory agent, especially in industrial areas other than carpet, yarn and fibre dyeing. These test stages consist of the electrochemical measurement techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) for diverse concentrations and durations. The adsorption of the viewed DMT molecule on the mild steel surface obeyed the Langmuir isotherm. The zero charge potential (PZC) of mild steel was also found to assess the inhibition mechanism in containing DMT solution. The inhibition performance of DMT on the mild steel in a 1.0 M HCl solution was also investigated using methods such as metal microscope, atomic force microscope (AFM) and field emission scanning electron microscope (FE-SEM).

“…This is mainly due to the presentation of inhibitor molecules in the solution, where a quasi-substitution process takes place, replacing the profoundly dielectric nature of water particles with the low dielectric natural inhibitor molecule and in-time it expands in thickness. 40 Accordingly, this would prevent the formation of the electric double layer and decrease the number for transferred electrons, which decreases the CR. We can account for these changes through the Helmholtz model eq 4 for the calculation of the double-layer capacitance.…”

“…The double-layer capacitance might have been diminished altogether by increasing the Pz series inhibitor concentration.

The inhibitory impact of low-cost synthesized pyrazoline derivatives named Pz series ( Pz1 and Pz2 ) on the corrosion of API 5L X60 carbon steel in 5 M HCl was inspected to serve as corrosion inhibitors against such a solution for its usage in the oilfield well acidization process. Also, the same compounds were unitized as biocides for sulfate-reducing bacteria (SRBs) to inhibit the microbial-induced corrosion effect. This study was conducted via several electrochemical techniques, namely, electrochemical potentiodynamic polarization (EP) and electrochemical impedance spectroscopy (EIS), in addition to computational density functional theory (DFT). The inhibition efficiency (IE) of Pz series on the corrosion of 5L X60 carbon steel in 5 M HCl was found to increase whenever the Pz series molecule concentration was increased. EP measurements revealed that Pz1 and Pz2 have both cathodic and anodic features (mixed inhibitor) and their corrosion IEs were around 90%. The physicochemical properties of the Pz1 and Pz2 compounds were studied using Langmuir adsorption isotherms, where the equilibrium adsorption data were found to follow it accurately. EIS outputs were found to comply with the values obtained from EP. Scanning electron microscopy was used to examine the topographic anisotropy between the inhibited and uninhibited 5L X60 carbon steel samples to double-check the electrochemical findings. DFT calculations and Monte Carlo simulations were utilized to predict the behavior of inhibitors and to rationalize the experimental results. The serial dilution bioassay technique was used to assess the Pz series as potential biocides to counter the effect of SRBs in compliance with the TM0194-2014-SG standard test method, and the results showed the potency of Pz series in inhibiting such bacterial growth.

“…In addition, the shape or size of the corrosion inhibitor molecule has a great impact on its performance (El Azzouzi et al, 2016;Zarrouk et al, 2016;Salim et al, 2019;Meeusen et al, 2020;Mishra et al, 2020). As seen previously, heterocyclic compounds have been studied by many researchers such as benzimidazoles, quinoxaline, oxazole, imidazole, quinoline, and tetrazole (Zhang et al, 2019a;Zhang et al, 2019b;El-Hajjaji et al, 2019;Qiang et al, 2020;Qiang et al, 2021). In addition, with the increase in the number of unsaturated bonds in the molecules, the corrosion inhibition performance of these compounds is improved.…”

The inhibitory performance of imidazole [1,2-a] pyrimidine derivatives, namely, 2,4-diphenylbenzo [4,5]imidazo [1,2-a]pyrimidine (DPIP) and 2-(4-octylphenyl)-4-phenylbenzo [4,5]imidazo [1,2-a]pyrimidine (OPIP), against mild steel corrosion in 1 mol L−1 HCl solution was studied by weight loss at different temperatures, potentiodynamic polarization curves (PDP), electrochemical impedance spectroscopy (EIS), and surface analysis technology. The two corrosion inhibitors showed an outstanding inhibition performance, and the inhibition efficiency achieved 91.9% for OPIP and 90.5% for DPIP at a concentration of 0.1 mmol L−1. Electrochemical methods showed that DPIP and OPIP behaved as mixed-type inhibitors. Density function theory (DFT) and molecular dynamic simulation (MD) were approached to theoretically study the relationship of the inhibitor structure and anti-corrosion performance, which were also compatible with the weight loss and electrochemical observations.
