“…Table 6 shows the electrochemical parameters obtained from the impedance curves of mild steel in HCl solutions at different pH with inhibitors S1 and S2 at 298 K. The impedance parameters summarized in Table 6, including the increase in R ct and the decrease in C dl with the rise in pH, indicate increased protection against corrosion. These observations align with previous research that identified these parameter variations as critical indicators of inhibitor effectiveness [38] …”

This research delineates the corrosion inhibitory efficiency of two newly synthesized benzoxazepine derivatives – [3,3‐dimethyl‐11‐phenyl‐3,4,5,11‐tetrahydrodibenzo[b,e] [1,4]oxazepine‐1(2 H)‐one (S1)] and [11‐(4‐chlorophenyl)‐3,3‐dimethyl‐3,4,5,11‐tetrahydrodibenzo[b,e][1,4]oxazepine‐1(2 H)‐one (S2)] – on mild steel in 1M HCl milieu. These derivatives were characterized by proton (1H NMR) and carbon (13C NMR) nuclear magnetic resonance spectroscopy. The experimental approach encompassed potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques. The corrosion inhibition efficacy of S1 and S2 was concentration‐dependent, with their efficiencies peaking at 92.0 % and 92.1 %, respectively, at a 10−3 M concentration. Surface characterization, conducted using scanning electron microscopy (SEM), energy‐dispersive X‐ray analysis (EDS), X‐ray diffraction (XRD), contact angle measurements, and X‐ray photoelectron spectroscopy (XPS), corroborated the formation of a protective barrier layer on the mild steel surface. Additionally, using an inductive approach, UV‐visible spectrometry was employed to elucidate the adsorption behaviors of these inhibitors on the steel surface. Density functional theory (DFT) and molecular dynamics (MD) simulations were utilized to decipher the interaction mechanisms and adsorption modalities, unveiling critical insights into the interactions of S1 and S2 with the mild steel surface. This comprehensive analysis highlights the robust corrosion inhibition potential of the newly synthesized benzoxazepine derivatives and illuminates their prospective utility as effective inhibitors for mild steel in corrosive environments.

“…Basic information on the mode of adsorption of these inhibitor molecules on metal surface can be drawn from the adsorption isotherm. There are several adsorption isotherms like Langmuir, Flory-Huggins, Temkin, Freundlich, and Frumkin, that explain the corrosioninhibition mechanism [90][91][92].…”

Use of inhibitor is proven as an efficient and widely accepted corrosion prevention method. Corrosion control of steel is an important activity in technical, economic, environmental and safety terms. This article enumerates several types of inhibitors used to combat corrosion in acidic medium. In this paper, literature on corrosion inhibitors has been reviewed and discussions are made on properties and efficiency of inhibitors. (The prominent features of our work on the mechanism of corrosion inhibitors have been highlighted and in a few cases have tried to predict its mechanism).

“…Today, the development of new corrosion inhibitors based on organic compounds having multiple bonds, nitrogen and/or sulfur atoms in their structures have been employed. Among these, several triazoles (Noor and AlMoubaraki 2008;Abouchane et al 2015;El Bakri et al 2008), tetrazole (Li et al 2007;Hmimou et al 2012), pyrazoles (Elkacimi et al 2012), imidazoles (Zerga et al 2010;Scendo and Hepel, 2007;Lamkaddem et al 2007), pyridazines (Larabi et al 2006;Benbouya et al 2014), quinoxaline Adardour et al 2015), benzamide derivatives (Adardour et al 2013), quinolone (El Faydy et al 2016), etc. have been used as corrosion inhibitors for metals in corrosive medium.…”

The inhibition efficiency of three substituted phenyltetrazole compounds, namely 5-(4-chlorophenyl)-1H-tetrazole (Cl-PT), 5-(4-methoxyphenyl)-1H-tetrazole (MO-PT), and 5-phenyl-1H-tetrazole (PT), for mild steel corrosion in 5.0 M HCl solution was\ investigated using weight loss measurements and electrochemical study. It is showed that these compounds are good inhibitors for mild steel corrosion in 5.0 M HCl solution which act as cathodic type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order of Cl-PT [ MO-PT [ PT which depended on their molecular structures. It is found also that these compounds toke its performance at different temperatures range from 298 to 328 K. In addition, the thermodynamic adsorption parameters at different concentrations were investigated and discussed. Finally, it is seen that the inhibition efficiency of the studied compounds increased with immersion time to reach a maximum at 12 h.
