“…Another study by Fernine et al used an ecological inhibitor based on Ocimum basilicium seed extract (OBSE) for the protection of AA2024 aluminum alloy exposed to a neutral solution of 3 wt% NaCl. 27 Based on EIS measurements, they showed a good corrosion efficiency yield of 95.5% at a concentration of 1 g L À1 . Polarization curves showed that the OBSE extract provided mixed inhibition, and thus the corrosion of AA2024 was delayed by OBSE.…”

In spite of the fact that aluminium and its combinations are regularly used like lightweight materials in a great deal of enterprises, they experience the ill effects of low erosion resistance. Corrosion is a natural phenomena that leads to the deterioration of the metal properties through its electrochemical interaction with the corrosive environment. The costs related to corrosion can be either direct (due to the replacement and maintenance) or indirect. A few strategies and methods have been utilized to mitigate corrosion in aluminium and its compounds under various conditions. Concerns raised over climate and human wellbeing have constrained industries to search for a more appropriate option for the protection of aluminium and its alloys from corrosion. This review emphasizes on the plant extracts applied for aluminium combination consumption restraint in NaCl medium. It summarizes the different techniques used for extraction. Additionally, an understanding to the adsorption isotherms has been discussed in brief.

“…In this paper, DFT was operated utilizing B3LYP with a basic 6-31 G/(d,p) process with Gaussian 09 programming. The quantum descriptors, for example, the fraction of electrons transferred from the inhibitor compound to the metal surface (∆N), softness (σ), LUMO and HOMO energy, total energy (E total ), dipole moment (µ), electronegativity (χ), global electrophilicity index (ω), and global hardness (η), which may be obtained through the following equations, where ηFe = 0 and χ = 7 eV [35]:…”

The continuous search for eco-friendly corrosion inhibitors due to differences in corrosive media remains an important point in corrosion control. The experimental studies on the corrosion inhibition of urea on mild steel in automotive gas oil (AGO) was conducted using gasometric techniques and scanning electron microscope (SEM). The theoretical approach on the density functional theory (DFT) on the urea molecule was carried out using Gaussian 09 software. The adsorption behavior of urea molecules on the surface of the mild steel was analyzed using Frumkin and Flory-Huggins adsorption isotherms models and Gibb’s free energy, respectively. The result of the experimental study shows a poor corrosion inhibitory effect of urea on mild steel in automobile gas oil (AGO) medium as the inhibition efficiency decreased from 69.30% in week 1 to 12% in week 11 at 200 ppm of inhibitor. The adsorption of urea on the mild steel surface obeys Frumkin’s adsorption isotherm model. Gibb’s free energy of adsorption of urea molecules onto mild steel surface revealed a physisorption mechanism. SEM results showed the non-inhibitive nature of urea on the studied mild steel. Quantum chemical parameters such as HOMO, LUMO, electron affinity, electronegativity, and the fraction of electrons transferred to the metal surface were calculated and interpreted to compare the experimental and theoretical results. The theoretical findings in the current investigation were not in agreement with the experimental result, thereby creating a need for further study using the electrochemical method.
