Recent progress in synthesis of MAX phases and oxidation & corrosion mechanism: a review

Layered MAX phases possess distinctive chemical, physical, electrical, and mechanical properties due to their amalgamation of metallic and ceramic characteristics. Understanding the corrosion mechanisms of MAX phases in various extreme environments is crucial. This paper commenced by scrutinizing synthesis techniques for MAX phase powders, thin films, and bulk materials, with a focus on fabrication processes and formation mechanisms. Subsequently, it delved into corrosion & oxidation mechanisms in diverse environments, emphasized their unique self-healing properties, and outlined future research directions. This comprehensive and systematic review aims to furnish researchers with effective guidance for selecting MAX phases based on different application environments.
