The increasing demand for magnesium-based materials for transportation has led to the development of surface treatments to enhance their performance. Active coatings stand out due to their ability to provide on-demand functionalities such as corrosion inhibition or self-healing. The current outlook on smart protection methods is dominated by organic-based materials, which present poor mechanical and thermal resistance that limits their applicability. This work pursues a new approach to achieve the active functionalisation of ceramic coatings, which inherently present excellent physical and chemical stability at high temperatures and exceptional performance in aggressive environments. The multi-functionalisation relies on the combined response of the ceramic matrix that provides long-term wear protection, with the incorporation of encapsulated inhibitors into nanocontainers that offer corrosion protection on demand. The inhibitors are released into the media when detecting pH changes arisen from electrochemical activity and will act locally at the anodic and cathodic sites inhibiting corrosion propagation.
