Abstract

A method for preparing self-synthesized tungsten carbide nano-grade wires, including the steps of: (a) coating a tungsten carbide film over a substrate top face; and (b) subjecting the substrate that has been coated with the tungsten carbide film to annealing, so as to form high density tungsten carbide nano-grade wires over the tungsten carbide film surface. The annealing temperature is set at 450 to 800 DEG C, and the relative annealing time is 2.5 hours to 5 min. The changes of crystal phase of the tungsten carbide film as occurred during the annealing process allows production of a great amount of tungsten carbide nano-grade wires over the tungsten carbide film without the need of using catalyst.
