Unbonded-phase tungsten carbide composite material and preparation method thereof
The invention belongs to the technical field of tungsten carbide composite materials, and discloses an unbonded-phase tungsten carbide composite material and a preparation method thereof. The unbonded-phase tungsten carbide composite material comprises the following raw materials in mass percentage: 88-94 percent of WC, 1.9-3.7 percent of Al2O3, 4.1-8.3 percent of ZrO2(3Y), and the balance of inevitable impurity content. The composite material prepared by the invention has unbonded phase, higher hardness, abrasive resistance and oxidation resistance, and better toughness; the used raw materials are easy to prepare, wide in sources and cheap in price; meanwhile, according to the invention, the compact composite material can be obtained under a relatively low sintering temperature.
