The invention provides titanium carbonitride-based metal ceramic and a preparation method and application thereof. The titanium carbonitride-based metal ceramic comprises a first ceramic phase, a second ceramic phase, a metal phase and a high-thermal-conductivity interface layer, wherein the first ceramic phase is titanium carbonitride, the second ceramic phase is carbides of IV, V and VI subgroup elements, the metal phase is cobalt and/or nickel, and the high-thermal-conductivity interface layer is of a continuous network-shaped structure generated by an aluminum-containing compound in situ among the metal phase, the first ceramic phase and the second ceramic phase. By introducing the aluminum-containing compound into raw materials, the microstructure of a traditional titanium carbonitride-based metal ceramic composite material is reconstructed, the thermal conductivity of the material is greatly improved, and then the service life of the material is prolonged. 本发明提供一种碳氮化钛基金属陶瓷及其制备方法和应用，所述碳氮化钛基金属陶瓷包括第一陶瓷相、第二
