Advancements in enhancing corrosion protection of Mg alloys: A comprehensive review on the synergistic effects of combining inhibitors with PEO coating

Journal of Magnesium and Alloys, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 1, 2024

Magnesium (Mg) alloys are lightweight materials with excellent mechanical properties, making them attractive for various applications, including aerospace, automotive, and biomedical industries. However, the practical application of Mg is limited due to their high susceptibility corrosion. Plasma electrolytic oxidation (PEO), or micro-arc (MAO), a coating method that boosts alloys' corrosion resistance. despite benefits PEO coatings, they can still exhibit certain limitations, such as failing maintain long-term protection result inherent porosity. To address these challenges, researchers have suggested use inhibitors in combination coatings on alloys. Inhibitors chemical compounds be incorporated into applied post-treatment further boost resistance PEO-coated Corrosion inhibitors, whether organic inorganic, act by forming protective barrier, hindering process, modifying surface properties reduce Containers made materials, polyelectrolyte shells, layered double hydroxides, polymer mesoporous inorganic materials. Encapsulating containers fully compatible matrix substrate promising approach incorporation. Laboratory studies shown results, demonstrating significant mitigation, extending service life alloy components aggressive environments, providing self-healing properties. In general, this review presents available information incorporation which lead improved performance demanding environments.

Organic inhibitors provide advantages for corrosion protection through formation of chelation layers. However, individual have weak inhibition efficiency when they are exposed to neutral media containing chloride ions. In this study, resistance Mg alloy AZ91D is synergistically enhanced by combining green chicory (CA) extracts with metal cations (Ca2+, Fe3+, Fe2+, and Ni2+). The Mg(OH)2 MgO products porous in the early stages immersion. main organic compounds CA including caffeic acid (Caf) chicoric (Chi), which combine inorganic via reaction, adsorbed on corroded area. large Bader charge adsorption energies Chi-Calcium-Chi (CaChi) complexes determined density functional theory calculations suggest that CaChi interacts strongly cations. combined organic–inorganic can therefore be absorbed firmly substrate form an active inhibitory layer.
