| description | The invention belongs to the technical field of hard alloy materials, and relates to a method for preparing tungsten carbide powder based on a self-ball-milling process, the preparation method adopts the self-ball-milling process, tungsten carbide with different particle sizes is taken as a raw material, the raw material is added into a ball mill, and target tungsten carbide powder can be obtained after ball milling and screening. The raw materials of tungsten carbide comprise coarse tungsten carbide, fine tungsten carbide and micro tungsten carbide; the ball mill is a closed space, nitrogen and argon are gradually introduced in the ball milling process, and gas introduction is stopped until the pressure in a tank of the ball mill reaches 0.8-1.5 Mpa; and the ball-milling rotation process is carried out alternately according to forward rotation and reverse rotation. According to the preparation method, the characteristics of high hardness and high wear resistance of tungsten carbide are utilized, parameters s |
