摘要	In order to prepare the coating by electrical explosion spray, using powders of Wolfram Carbide as spraying material, we developed a method of electrical explosion spraying of continuously feeding powder in the constraining tube, by which the test of WC powder spraying was conducted. Moreover, the effects of initial voltage and spraying distance on characteristics of coating were analyzed. The results show that, in a certain range of spraying distance, the liquid spraying coating of WC particles in the molten form is formed by this method, and this coating is dense and has a higher bonding strength with substrate. At a very small spraying distance, such as 1 mm, the surface of coating has vapor deposition morphology. At a farther spraying distance, a part of molten particles begin solidifying solid particles in explosion products, and form spraying coating which has solid particles. The compaction of coating declines and coating has a lower bonding strength with substrate. At the high initial voltage, the range of spraying distance increases where liquid spraying coating and spraying coating with solid particles are obtained.
