“…7 shows the Nyquist diagrams for the CS in 1M HCl solution without and with the addition of different concentrations of HME, MDE, EAE, and BE. As observed, these diagrams have a similar shape, which are semi-circles for all the tested specimens, indicating that the corrosion and its inhibition are controlled by the chargetransfer mechanism and that the reaction mechanism did not change after adding the inhibitor [60,61] .Because the frequencies are spread out and regarding the roughness and the nonuniformity of the electrode surface, these capacitive loops are not perfect [17,65] .…”

“…On the other hand, corrosion inhibitors are chemicals that have heteroatoms (S, O, N…),multiple bonds, and aromatic rings in their structures [17,18] . They slow down corrosion when added in small amounts to a corrosive environment, like that found in pickling [19] or other acidic processes [20,21] .…”

“…In this context, plant extracts have shown very good performance as additives [18,[29][30][31][32][33] in electroplating baths in terms of enhancing the quality of plating (roughness, porosity, brightness, and corrosion resistance) [8] . Furthermore, they have proven to be valuable inhibitors in acidic solutions, effectively reducing the corrosion rate [17,34,35] .…”

The ability of Centaurea napifolia extracts, hydro-methanolic (HME), methylene dichloride (MDE), ethyl acetate (EAE), and n-butanol (BE), to inhibit carbon steel (CS) corrosion in acidic environments and to function as additives in mild steel (MS) electroplating baths with pure zinc is assessed in this study. Potentiodynamic polarization, gravimetric method, scanning electron microscopy with energy dispersive spectroscopy (SEM/EDS), profilometer, and electrochemical impedance spectroscopy (EIS) were used in this investigation to evaluate the corrosion behavior. Brightness, thickness, and adhesion strength served as indicators of the zinc's quality when deposited on the various substrates. The findings demonstrated that the addition of plant extracts enhanced the coating's quality, resulting in less porous plates with improved adhesion, increased brightness, and more corrosion resistance. The optimal corrosion rate is 0.038 mm/y obtained in the presence of 3.2 g/l of BE in the electroplating bath, compared to 1.137 mm/y without the additive and 3.783 mm/y for unplated MS. Moreover, the current density decreased from 0.3235 mA/cm² for unplated MS to 0.0972 mA/cm² and 0.0033 mA/cm² for plated without additive and when adding 3.2 g/l of the BE, respectively. The extracts were also evaluated as CS corrosion inhibitors in a 1M HCl solution. The results show that the inhibitor's ability to stop the corrosion reaction increased as the concentration went up but decreased as the temperature went up, with a maximum efficiency of 700 ppm (81%), 800 ppm (73%), 700 ppm (82%), and 700 ppm (78%), for HME, MDE, EAE, and BE, respectively. The adsorption process of all the extracts on the metallic surface obeys the Langmuir isotherm. The thermodynamic parameters of adsorption were calculated and discussed, and the results indicated that the adsorption was physical, spontaneous, and exothermic.

“…These products have been frequently studied because they provide simple solutions to protect metals from corrosion in the aquatic environment. With the originality of being the only means of interference of the corrosive environment with steel, these compounds reduce the rate of corrosion of metals when added in appropriate amounts, without apparent change [9,14].…”

We highlight in this chapter the corrosion protection using phenolic extract. The building of mathematical models using experimental results obtained from the investigation of phenolic molecules or fractions extracted from Echium italicum L., used as corrosion inhibitors is one of the new trends in the study of steel protection. The evaluation of the corrosion inhibition of carbon steel (API 5 L-X60) in a solution 1 M of hydrochloric acid was performed using gravimetric method, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The predicted mathematical relationships between the corrosion rate and the inhibitory efficiency in the presence of the butanolic extract of Echium italicum L. (BEEI), when increasing temperature proved a good agreement between experimental and mathematical studies.
