“…Despite this, several limitations are associated with the PEO technique, including a limited range of compositions, high porosity, and high energy consumption. In general, the properties of PEO coatings are determined mainly by the design and microstructure, controlled by factors such as the method, solution, and substrate used to create them [70]. Optimizing the electrolyte composition is an effective strategy to enhance the properties of PEO coatings.…”

Magnesium has been a focal point of significant exploration in the biomedical engineering domain for many years due to its exceptional attributes, encompassing impressive specific strength, low density, excellent damping abilities, biodegradability, and the sought-after quality of biocompatibility. The primary drawback associated with magnesium-based implants is their susceptibility to corrosion and wear in physiological environments, which represents a significant limitation. Research findings have established that plasma electrolytic oxidation (PEO) induces substantial modifications in the surface characteristics and corrosion behavior of magnesium and its alloy counterparts. By subjecting the surface to high voltages, a porous ceramic coating is formed, resulting in not only altered surface properties and corrosion resistance, but also enhanced wear resistance. However, a drawback of the PEO process is that excessive pore formation and porosity within the shell could potentially undermine the coating’s corrosion and wear resistances. Altering the electrolyte conditions by introducing micro- and nano-particles can serve as a valuable approach to decrease coating porosity and enhance their ultimate characteristics. This paper evaluates the particle adhesion, composition, corrosion, and wear performances of particle-incorporated coatings applied to magnesium alloys through the PEO method.

Mg alloy is the preferred material for the lightweight development of manufacturing industry. However, its application is limited due to the poor wear resistance and corrosion resistance. In this experiment, Mg‐Al LDH/SC (Layered double hydroxide/Steam coating) composite coatings were prepared on the surface of LA43M Mg‐Li alloy by steam treatment and in‐situ hydrothermal method for different times (12 h, 18 h, 24 h, 30 h and 36 h). The morphology and structure of the coatings were characterized by SEM, EDS, and XRD, and the friction wear test of the coatings was carried out. The corrosion resistance of the coatings was evaluated by immersion tests and hydrogen evolution experiments. The effect of hydrothermal time on the growth characteristics, wear resistance, and corrosion behavior of LDH/SC coatings in 3.5 wt.% NaCl solution was systematically investigated. In addition, the growth mechanism and corrosion resistance mechanism of the LDH/SC coating were discussed. The results show that the composite coatings is mainly composed of LDH and Mg(OH)2 phases. Appropriately prolonging the hydrothermal reaction time is beneficial to the nucleation and growth of LDH. When the hydrothermal time is 30 h, the prepared coating has the best density, and the prepared coating can significantly improve the corrosion resistance and friction wear properties of the substrate.This article is protected by copyright.

The synthesis of a novel eco-friendly anionic Gemini surfactant, pursuing three parameters of green chemistry: economic, environmental factor, and mass reaction efficiency is developed as a corrosion inhibitor for AZ31 Mg alloy. Herein, the corrosion inhibition ability of novel EDTA-based dimeric surfactant on AZ31 Mg alloy in corrosive media with varying concentrations of NaCl and Na2SO4 at temperatures between 30–50 °C were studied. The surfactant’s molecular structure is affirmed by FT-IR, NMR, and LC–MS techniques. Electrochemical techniques and surface morphology were employed to evaluate the corrosion inhibition efficiency. The inhibitor studied exhibited appreciable corrosion inhibition at 30 °C. The surfactant shows physical adsorption as per the data obtained in the Gibbs free energy and enthalpy of adsorption studies. The adsorption of the inhibitor was found to be a film-like layer on the surface of AZ31 Mg alloy and, is confirmed by SEM–EDX and XPS techniques. In addition, theoretical simulations were performed to compare with experimental results. Conclusively, the work provides a deeper understanding of the intricacies involved in the development of a new anionic dimeric surfactant as an effective corrosion inhibitor.
