Abstract

In this investigation, the feasibility of direct synthesis and production of ultrafine tungsten carbide in a high-speed jet of tungsten carbon electric discharge plasma is shown. According to X-ray diffraction and electron microscopy, the plasmadynamic synthesis product consists of the cubic modification of tungsten carbide mostly, the structure of which is closest to the structural model of WC1 − x. Furthermore, the powder contains crystalline tungsten W, tungsten carbon W2C, and graphite C, the total weight of that amount being about 2.0 wt %. The particles of the tungsten material have a two-layer carbon shell.
