摘要

Carbon can be applied as an additive to improve the properties of ceramic, but it has some damage effects on the matrix. Herein, the hybrid material of TiO₂-supported carbon layers (C/TiO₂) was synthesized through the oxidation of Ti₃C₂ at high temperature, which consisted of the large-scale carbon platelets with a thickness of ∼33.9 nm and the micron-scale TiO₂ particles scattered between layers. By adding of C/TiO₂ into Si₃N₄, the fracture toughness and the tribological properties of the composite achieved a comprehensive enhancement, importantly, without sacrificing the hardness. This was attributed to the bridging between carbon layers and grains, and the loading-support of the in-situ formed TiN.
