Toughening Mechanisms of Al2O3/TiC Ceramic Composite with Carbon Additive

Abstract

Abstract: With carbon as an additive, the fracture toughness of Al₂O₃/TiC ceramic material fabricated by hot pressing technology is increased by 20% than that of
Al₂O₃/TiC composite without any carbon added. The results of theoretical and experimental analyses show that the existing of weak interfaces in the ceramic
material is one of the effective approaches to achieve higher fracture toughness. The added carbon, existing as a form of graphite, can result in not only the
formation of spontaneous microcracks but also the formation of weak interfaces. As a result of the comprehensive integration and synergism of varieties of single
toughening mechanisms such as crack bridging, crack branching and crack defection etc., the fracture toughness of Al₂O₃/TiC ceramic material can be enhanced obviously.

Key words: ceramic material, alumina, carbon, additive, toughening mechanism
