Summary: This work introduces a novel nanocomposite coating with dual-action self-healing corrosion protection activated by the photothermal response of plasmonic titanium nitride nanoparticles, which efficiently suppresses the corrosion process at the exposed metal surface. The surface characterization and electrochemical measurement results proved that the nanocomposite coating exhibited optimal corrosion protection and excellent self-healing performance under NIR illumination within 30 seconds. This photo-controlled self-healing approach has the potential to design next-generation self-healing coatings with ultrafast response time and high healing efficiency.

Summary: A novel anti-corrosion composite coating, which combines micro-arc oxidation (MAO), ionic liquid, and superhydrophobic coating, is fabricated for magnesium alloys. The successful preparation of the composite coating is characterized by various techniques, and its excellent anti-corrosion performance is attributed to the synergistic effect of the superhydrophobic feature, the corrosion inhibition of the ionic liquid, and the physical barrier of the MAO coating. The incorporation of the ionic liquid not only offers self-healing capability but also enhances the overall anti-corrosion performance of the composite coating by sealing the pores on the MAO surface.

Summary: Novel coatings with self-healing and osteoimmunomodulation functions were fabricated to enhance corrosion resistance and osseointegration of Mg-based endosseous implants. The coatings showed effective protection to Mg in vitro and in vivo through cFMSNs as corrosion inhibitors, while curcumin release improved immune microenvironment favoring osteo-differentiation and extracellular matrix mineralization of bone marrow stem cells, leading to better osseointegration. Coatings with higher cFMSNs content exhibited superior immunomodulatory efficiency and achieved the best osseointegration in vivo.

Summary: Magnesium (Mg) and its alloys are favored for lightweighting in automotive and biomedical applications due to their excellent biocompatibility and osseointegration properties. However, their poor corrosion resistance restricts their use in many applications, necessitating intensive research to improve their anti-corrosion stability. Protective layer coatings on Mg have been proven to be highly effective in enhancing anti-corrosion stability. This article provides an overview of current chemical-based coatings applied to Mg alloys, including anodizing, plasma electrolytic oxidation, electrodeposition, electroless plating, chemical conversion coating, sol-gel coating, layered double hydroxide, and layer-by-layer assembly. The progress in coating fabrication, corrosion performance breakthroughs, and coating mechanisms and functional perspectives are discussed. As significant advancements have been made in developing corrosion protection approaches for Mg alloys, there is a vast potential for exploring chemical-based coatings. Despite the development of future functional and smart coatings, traditional chemical-based coatings retain comparative functional qualities and require a deeper understanding of aspects such as ease of fabrication, coating strength, and actual anti-corrosion performance.
