Abstract

Disclosed in the present invention are a tungsten carbide composite material comprising aluminium oxide particles and silicon nitride whiskers and a preparation process thereof. The tungsten carbide composite material comprises 0.5-3% aluminium oxide particles by mass percent, and 0.4-10% silicon nitride whiskers by mass percent, and the balance is tungsten carbide and an inevitable impurity phase; the silicon nitride whiskers are authigenic ß-Si3N4 whiskers. The WC composite material prepared in the present invention does not contain any metal bonding phase, has good hardness, abrasion resistance and mechanical performance at high temperatures, and medium toughness; the present invention can not only reduce the costs of preparing the WC composite material, but also effectively expand the scope of application thereof; and the material is suitable as a cutter such as a indexable blade, etc., a plastic machining tool such as a wire-drawing die, etc., and is also suitable as a shearing tool, such as a punching and shearing die, etc.
