The preparation method of the enhanced metal ceramic abrasion-resistant composite material just comprises mixing, drying, sintering and cooling. The metal ceramic composite material has good properties that the bending resistant strength is up to 2500 MPa and the Rockwell hardness is up to 93; in addition, the metal ceramic composite material also has good properties of abrasion resistance and high temperature resistance; the preparation method is simple and feasible and suitable for application and popularization on a large scale.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant composite materials, and in particular relates to a reinforced cermet wear-resistant composite material and a preparation method thereof. Background technique [0002] Cermet is a composite material composed of ceramic hard phase and metal or alloy binder phase. Cermet not only maintains the characteristics of high strength, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability of ceramics, but also Has good metal toughness and plasticity. [0003] Cermets have gone through three generations so far. The first generation was during the "World War II", Germany produced cermets with Ni bonded TiC; The wettability of other carbides improves the toughness of the material; the third generation of cermets introduces nitrides into the hard phase of the alloy and changes the single phase into a composite phase. The binder phase is also improved by...
