High-entropy carbide ceramic-based nano composite cutter material and preparation method thereof
The invention relates to the technical field of ceramic-based composite materials, in particular to a high-toughness high-entropy carbide ceramic-based composite tool material and a preparation method thereof. The metal Ni is used as a metal binding phase of the high-entropy carbide ceramic, the nano Al2O3 is used as a ceramic binding phase, and meanwhile, the graphene is introduced as a strengthening and toughening phase of the high-entropy carbide ceramic, so that multiple properties such as hardness, bending strength and fracture toughness of the high-entropy ceramic material are synergistically improved. Through multi-scale cross-dimension coupling and regulation of micron-scale metal Ni, nano-scale ceramic Al2O3 and two-dimensional graphene nanosheets, a proper spark plasma sintering process is adopted, and the high-entropy carbide ceramic-based composite material with optimal performance configuration is obtained. The material has potential application value in the field of cutter preparation and application.
