Titanium carbide-based hard alloy taking nickel-molybdenum alloy as adhesive and preparation method thereof

The invention discloses a titanium carbide-based hard alloy taking a nickel-molybdenum alloy as an adhesive and a preparation method thereof. The titanium carbide-based hard alloy consists of the following raw materials in percentage by mass: 13 to 20 percent of nickel powder, 7 to 10 percent of molybdenum powder and the balance of titanium carbide powder. The preparation method comprises the following steps of: adding the nickel powder, the molybdenum powder and the titanium carbide powder into a ball mill for wet milling, filtering and drying; adding paraffin wax; uniformly mixing, drying and performing compression molding; putting the mixture into a hydrogen atmosphere after molding and preserving heat at the temperature of between 300 and 500 DEG C for 2 to 3 hours; and sintering the mixture under the vacuum degree of 1*10 to 5*10 Pa at the temperature of between 1,400 and 1,450 DEG C so as to obtain a finished product. An alloy material prepared by the method has high hardness, high wear resistance, high corrosion resistance, low consumption of strategic resources, low porosity and high performance price ratio, can be applied to (half) finish machining of low carbon steel continuous cutting and can be taken as a substrate material for a diamond coating cutter.
