Preparation method of nanometer tungsten carbide powder

Tungsten powder as raw material, the technology of nanometer tungsten carbide powder prepared by plasma synergistic ball-Milling activated carbonation method, the core is the introduction of low-temperature plasma in the tungsten powder ball grinding cavity, the effect of plasma field in the ball grinding cavity and the interaction of the plasma field and mechanical energy to strengthen the mechanical alloying of tungsten powder. In particular, to improve the effect of activated tungsten powder, the synthesis of nanometer tungsten carbide powder at low temperature was realized.

The technology of dielectric barrier discharge plasma synergistic mechanical alloying mainly includes: it satisfies the complex moving plasma discharge technology of tungsten powder in ball milling cavity, satisfies the technology of dielectric barrier discharge plasma power, the technology of tungsten powder mechanical ball Milling and plasma discharge parameters to synthesize nanometer tungsten carbide.
