MXene-reinforced alumina ceramic composites

Ti3C2Tx, a typical MXene, was incorporated into alumina (Al2O3) to obtain ceramic composites and its effects on their microstructures and mechanical properties were investigated. The investigation results showed that MXene was well-dispersed in the ceramic matrix and significantly reinforced alumina. At 2 wt% Ti3C2Tx, the fracture toughness, bending strength and hardness was improved by similar to 300%, similar to 150%, similar to 300%, respectively. The toughening mechanisms associated with crack deflection induced by Ti3C2Tx were discussed.
