“…To understand the fraction of electrons transferred (ΔN) between the brass and the inhibitors, we rely on copper (ΔNCu) because of its high percentage in this alloy (brass) 21 . According to the simple charge transfer by donation and back-donation (∆Eback-donation) model proposed by Gomez et al 27 , an electronic back-donation process could occur governing the interaction between the inhibitor molecule and the metal surface.…”

“…As a part of our ongoing research project, in our recently published paper 21 , we discussed the inhibitory performances of two Ammi visnaga (L.) lam extracts collected in 2016 (EO16) and 2018 (EO18) on the corrosion of brass in 3% NaCl medium using electrochemical methods. These methods are based on the potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS).…”

“…Besides, molecular dynamic simulation based on the Monte Carlo (MC) method was adopted to complete the DFT calculations and to look for a logical explanation of the high inhibitory power of EO18 compared to EO16. Besides, since brass was used in the experimental study and because copper constitutes the largest fraction of brass 21 , we intended to comprehend the interaction of the studied inhibitors on the surface of copper.…”

The computational study was carried out to understand the anti-corrosion properties of Croweacin, a major chemical component of two essential oils of Ammi visnaga (L.) Lam collected from northern Morocco in 2016 (EO16) and 2018 (EO18) against brass corrosion in a 3% NaCl medium. The study, moreover, considers the inhibitory effect of some minor compounds of EO18 such as Eugenol, Trans-Anethole, α-Isophorone, and Thymol. In this context, the quantum mechanics modelling using the density functional theory (DFT) method with B3LYP /6-31G (d, p) were conducted in the aqueous medium by the use of the IEFPCM model and SCRF theory. The DFT method was adopted to identify, analyze and interpret several elements such as the electronic features, the Frontier Molecular Orbitals (FMO) diagram, Molecular Electrostatic Potential (MEP), contours maps of the electrostatic potential (ESP), and the Mulliken population analysis. The DFT demonstrated that the studied compounds are excellent corrosion inhibitors.Furthermore, the Monte Carlo (MC) type simulation of molecular dynamics (MD) was carried out to provide information on the adsorption mechanism of the studied inhibitors through the active sites on the metal surface. This method informed us that the studied inhibitors have high adsorption energy when interacting with the metal surface, especially for Croweacin (-68.63 kcal/mol). The results obtained from DFT and the MC type simulations are in good agreement.

“…Moreover, brass degradation due to pitting corrosion in chloride-containing solution leads to structural failure and serious economic losses [5,6]. Therefore, the stability of Cu-Zn alloys in seawater has been extensively studied, while investigating different parameters: temperature [7], adding an alloying element [8][9][10], immersion duration [11], pH [12,13], [Cl − ] [14], surface inclination [13], inhibitor presence [15][16][17][18][19][20][21]…”

The main objective of the investigation is to identify the role of beta phase on the corrosion behavior of CuZn alloys in chloride solution. The experimental study was based on the characterization and identification of the anodized brass films formed on the surface of two alloys: CuZn30 and CuZn39, abbreviated by CuZnα and CuZnαβ. Oxidation was carried out at different potentials chosen from the anodic polarization curves recorded beforehand with the two alloys. The main analysis techniques are AFM, SEM, EDS and XRD. Results indicate that the corrosion mechanism is similar for both alpha and alpha beta brasses and followed the same succession of steps. Nevertheless, the rate of dezincification is higher in the case of CuZnαβ: the surface of the attack is larger, and different plugs could be created at the same potential. Therefore, the composition of the protective layer is more diverse than that of CuZnα, while much more varied oxide and hydroxide species are likely to be formed.

“…These compounds have shown better corrosion inhibition but may damage the environment due to its toxicity. In terms of protection of the environment, essential oils were tested, where eugenol 10 and Ammi visnaga (L.) Lam 11 , were the inhibitors. Results showed high inhibition performances of brass in 3% NaCl solution.…”

Corrosion control of copper alloys such as brass is of great interest to researchers and scientists. Clays become materials of choice as corrosion inhibitors and as their reservoir in corrosive environments. The effect of Rhassoul on the corrosion of Cu-36Zn alloy in 3% NaCl solution has been studied. Electrochemical techniques showed that the optimum concentration was 1g/L showing the highest inhibition efficiency (82%). This concentration was evaluated at five different temperatures. In order to determine the influence of purification, this result was compared to that of the homoionic clay labeled Na+-ST and to the pure calcite. Chemical composition of the brass specimen and solutions were done by inductively coupled plasma atomic emission spectrometry (ICP-AES) and atomic absorption (AA) respectively. The effectiveness of this clay against the dissolution of Zinc reached 61%. XRD technique demonstrated the homoionization of this clay by shifting the basal spacing d001.
