“…The thermodynamic functions for carbon steel dissolution, in the presence and absence of various vicine concentrations, were obtained by applying the Arrhenius equation and the transition state equation [26][27][28]. The data that were used to plot Arrhenius relationship are summarized in Table 4, and the plotting is shown in Fig.…”

In the present study, vicine was extracted from sunflower seeds, and has been evaluated as a corrosion inhibitor for carbon steel alloy, at different concentrations and temperatures. Vicine showed maximum inhibiting efficiency of 97%, at 25 ºC. The inhibitor's efficiency was reduced when the temperature increased. Kinetic parameters (Ea, ΔH*, ΔG* and ΔS*) were calculated. The corrosion reaction was suppressed by vicine, because the energy barrier of the corrosion reaction was increased, and it became non-spontaneous, by an endothermic process. Furthermore, ΔHads, ΔGads and ΔSads were also calculated, and showed that the inhibitor was physically adsorbed by a spontaneous and exothermic process. The corrosion was inhibited by simple blocking the reaction sites. The adsorption process obeyed the Langmuir adsorption isotherm. The theoretical and experimental studies depicted that the inhibitor worked by a mixture of physicalchemical adsorption modes.

“…In sight of this, many alternative green corrosion inhibitors have now been developed. Al-Sahlanee et al 8 found that Sesbania sesban extract can be used as good corrosion inhibitors for carbon steel in acidic medium. Recently, aqueous extracts of Aleo vera 9 and Garlic extract 10 and Justicia gendarussa plant 11 have been reported to be efficient corrosion inhibitors for steel in acid solutions.…”

The corrosion protection of mild steel is a significant concern among the corrosion scientist and material technologist 1 . Although, mild steel has remarkable economic and substantial applications, its poor corrosion resistance in acids confines its usage 2 . Acid solutions are widely used in pickling of steel, chemical cleaning/ processing, ore production and oil well acidification 3 . Several methods are used to control the corrosion process but application of inhibitors has been proven to be most practical and efficient for this purpose. Organic compounds containing nitrogen, sulphur and oxygen can be used as efficient corrosion inhibitors 4-

Corrosion is a crucial problem worldwide that heavily affects natural and industrial environments and can cause machinery breakdown and deterioration of construction assemblies, thus threatening the lives of humans and accelerating the consumption of natural metal reservoirs. In this study, we deployed passiflora incarnata extract (PIE) as an eco-friendly green inhibitor to prevent API 5CT N80 (CS-N80) corrosion in 1 M HCl. The chromatograms of the gas chromatography−mass spectroscopy analysis of PIE have identified 25 compounds. The weight loss method reveals that 150 ppm of the extract offers 90.4% inhibition efficiency (IE) to CS-N80 immersed in 1 M HCl solution at 25 °C. However, at higher temperatures (45 °C), % IE increases and reaches 92.1%. The electrochemical characterization of the adsorbed layer on CS-N80 was tested by utilizing electrochemical methods (electrochemical impedance spectroscopy and polarization) in 1 M HCl. Polarization diagrams displayed that PIE is a mixed-type inhibitor that retards CS-N80 corrosion. Temkin adsorption isotherm is the best fit for adsorbed PIE on the CS-N80 surface. IE was improved by raising the temperature (chemical adsorption). Examining the morphology of CS-N80 sheets through scanning electron microscopy, energy-dispersive X-ray, X-ray photoelectron spectroscopy, and Fourier transform infrared analysis furnishes valuable insights into their surface characteristics. The results of a quantum chemical computation show that the three PIE components have strong anticorrosion properties. According to findings from molecular dynamics simulations, the three PIE components can have a high binding energy and can be adsorbed in a parallel manner at the Fe(110) surface. All tests have shown that the PIE composite conversion adsorbed with a self-healing property and lower corrosion current density was precipitated on the steel surface.
