“…The effect of perezone concentration and impregnated MgAl coating on AS21 magnesium alloys was investigated by Casillas et al 35 When the inhibitor was treated with talc, the corrosion prevention effect significantly improved, and the corrosion suppression efficiency reached 91.1%. To elucidate the adsorption mechanism of perezone on the magnesium surface, DFT calculations were performed.…”

Self‐healing coatings possess the remarkable ability to autonomously mend damages and restore their corrosion protection capabilities, which are compromised due to environmental influences or external forces. The progression of computational materials science has significantly bolstered theoretical explorations into self‐healing anti‐corrosion coatings. Such inquiries enhance our grasp of self‐healing mechanisms, refine coating efficacy, and curtail the expenditures associated with empirical approaches. The research advancements in computational materials science for self‐healing coatings are reviewed here. It delineates the theoretical elucidation of self‐healing mechanisms through the lens of molecular dynamics, density functional theory, Monte Carlo simulations, and finite element analysis. The computational exploration of intrinsic self‐healing coatings primarily involves dynamic reversible covalent bonds, dynamic reversible non‐covalent bonds, and shape memory effect; whereas, extrinsic self‐healing coatings concentrate on the modalities of film‐forming substances and the adsorption behaviours of corrosion inhibitors. These simulation techniques not only shed light on the self‐healing processes at a microscopic scale but also enable the prediction and enhancement of the macroscopic performance attributes of the coatings in practical applications. The merits and constraints of these computational simulation methodologies when applied to self‐healing coatings are critically assessed. Looking ahead, efforts will be directed towards a more profound amalgamation of computational simulations, empirical investigations, and artificial intelligence. This will pave the way for creating a comprehensive database cataloguing the self‐healing properties of coatings, thereby streamlining material selection and design with greater efficiency.

In this research, the high efficacy of Mentha spicata L. extract, commonly known as spearmint, as a corrosion inhibitor with an efficacy rate of 86.98% is highlighted. Analytical techniques, such as scanning electron microscopy (SEM) to obtain a detailed morphological view, Fourier transform infrared spectroscopy (FTIR) to identify the functional groups of flavonoids, and electrochemical impedance spectroscopy (EIS) and Tafel plots for a corrosion assessment, were employed. This study pioneers a greener alternative to traditional corrosion inhibition methods. The distinctive aspect of this research is the innovative spray coating application method used to deliver the spearmint extract onto structural steel. This method involves the strategic use of an airbrush for spray coating, ensuring the uniform and efficient deposition of the organic inhibitor, thus forming a protective barrier against corrosion. This spray coating technique is emerging as an innovative approach for the industrial application of natural corrosion inhibitors, demonstrating significant advances in the corrosion resistance of coated steel. The results not only corroborate the efficacy of natural inhibitors, but also highlight the critical role that sophisticated application techniques play in improving their industrial viability. This methodological innovation presents a pathway to sustainable practices in corrosion management, prioritizing environmental protection and ecological footprint reduction in the quest for corrosion mitigation.
