Research demonstrates enhanced damage tolerance in MAX-phase ceramic composites for high-temperature applications, implying potential uses in industrial turbines.
Continuous fibre-reinforced MAX-phase ceramic matrix composites (CMCs) are emerging as superior materials for high-temperature and oxidation-resistant applications. These composites combine the durability and resistance of traditional oxide ceramics with the easier processing and damage tolerance of metals, making them viable alternatives to conventional high-temperature alloys and ceramics like alumina, carbon, or silicon carbide. The materials are produced using molten salt shield synthesis (MS3), which allows for the scalable production of MAX-Phase powders. This research focuses on slurry-based processing methods, specifically pressure slip casting, to create both monolithic and fibre-reinforced ceramic bodies. Incorporating braided alumina fibres improves the damage tolerance of the MAX phase. The advancements in material processing and the potential for these materials to be used in the hot gas sections of industrial and aviation gas turbines are discussed. This study showcases significant developments in the field, highlighting the practical applications and benefits of MAX-phase CMCs in demanding thermal environments.
