Zinc, an important nonferrous metal, is the fourth most used metal in the world. It has innumerable uses in industrial as well as in other segments. The primary utility of zinc is in galvanization and as an anode in the battery. Steel coated with zinc, which is known as galvanized steel, is widely used in industries. Even though zinc protects many metals from undergoing corrosion, by itself, it undergoes corrosion in several acidic, alkaline, and neutral environments. The corrosion behavior of zinc is significant in all industries where it is utilized either directly or indirectly in the form of a sacrificial coating. In-depth analysis of the reported literature indicated that corrosion attenuation of zinc in acidic and alkaline medium was studied by many researchers, and various classes of inhibitors were tried under varying experimental conditions. Most inhibitors can be amalgamated as excellent inhibitors with an inhibition efficiency of 80–90%. Even though this is a subject of intense research, systematic documentation on the same is not available in the literature. This review consolidates research work on corrosion and inhibition studies of zinc and galvanized steel over a period of three decades.

“…Weight loss methods have been conducted with mild steel specimens through the exposure of the specimen to the 1 M hydrochloric acid solution without and with the addition of 4-(Benzoimidazole-2-yl)pyridine at various concentrations (0.001, 0.002, 0.003, 0.004, and 0.005 M). After a period (1, 5, 10, 24, and 48 h) the mild steel specimen has been taken out washed with double distilled water and acetone than dried by the oven and the weight was measured accurately [20][21][22].…”

The corrosion inhibition efficiency of the novel pyridine namely, 4-(Benzoimidazole-2-yl)pyridine has been studied for mild steel in a 1 M hydrochloric acid environment by utilizing gravimetrical techniques. The synthesized inhibitor exhibits a significant inhibitive efficiency of 93.8% at 0.005 M. The adsorption isotherm of the investigated inhibitor on mild steel surface obeys the Langmuir isotherm. Surface morphology investigated by utilizing scanning electron microscopy (SEM) demonstrates a smooth metal surface with the addition of 4-(Benzoimidazole-2-yl)pyridine in a hydrochloric acid environment. Quantum chemical calculations using density functional theory (DFT) have been used to investigate the molecular structure and behavior of 4-(Benzoimidazole-2-yl) pyridine as a corrosion inhibitor. Different parameters have been calculated using DFT, such as energies of highest occupied molecular orbital and lowest occupied molecular orbital (EHOMO and ELUMO), energy gap (∆E), and dipole moment (μ). These parameters were important to elucidate the behavior of the investigated molecule as a corrosion inhibitor in acidic solution and also suggest the mechanism of inhibition.

A new benzylidene derivative, namely 3,, has been synthesized and instrumentally confirmed with Elemental Analysis (CHN), Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared Spectroscopy (FT-IR). Titanium Dioxide (TiO 2 ) nanoparticles (NPs) were synthesized and characterized by X-ray. The mutualistic complementary dependence of BPTA with TiO 2 nanoparticles as anticorrosive inhibitor on mild steel (MS) in 1.0 M hydrochloric acid has been tested at various concentrations and various temperatures. The methodological work was achieved by gravimetric measurement methods complemented with surface analysis. The synthesized inhibitor concentrations were 0.1 mM to 0.5 mM and the temperatures ranging from 303-333 K. The BPTA with TiO 2 -NP as a synergistic inhibitor becomes superior inhibitive effects with more than 96% inhibition competence of MS coupons in a harsh acidic medium. The efficiency of the inhibition improved with increasing BPTA content and also increase with the Synergistic effects of BPTA with TiO 2 -NP. The excellent effectiveness was performed with the 0.5 mM concentration of BPTA and become higher with adding of TiO 2 -NP rising to the maximum inhibition efficiency (IE). However, the inhibition efficacy declined as the temperature rises. Results of BPTA as corrosion inhibitor indicated the obedience of the adsorption of the inhibitor of mixed type on the surface of MS to Langmuir adsorption isotherm. It was found that the BPTA and performance depend on the Synergistic effects, concentrations of the TiO 2 -NP and BPTA, in addition to the solution temperature. Nevertheless, the quantum calculations have confirmed the direct correlation of the electronic characteristics of BPTA with the corrosive inhibitive influence.
