英文摘要	Electrical explosive spraying is a new surface modification technology. The diversification and morphology of sprayed raw materials are important factors to promote the application of this technology into engineering. Based on the understanding of traditional wire electrical explosive spraying, a powder conductor,as a raw material, was adopted for this electrical explosive spraying experiment. A set of electrical explosive spraying device for the powder conductor was developed and the energy deposition characteristics of powder electrical explosive spraying were studied preliminarily. The results show that, with the change of charging voltage(8~13 kV) and particle size(10~100 μm), there are two energy deposition modes in powder electrical explosion, namely, smooth oscillation mode () and catastrophe mode(). In the smooth oscillation mode, it is difficult to form an effective coating on the substrate surface. While in the catastrophe mode, it is easier to form a high-quality coatings. It is concluded that the essence of the powder energy deposition mode is controlled by the competition between the resistance of powder system and the gap resistance of interparticle. Therefore, the powder energy deposition mode can be transformed from the smooth oscillation to the catastrophe by increasing charging voltage and reducing particle size simultaneously, and hence the resultant coating quality can be improved. © 2020, High Voltage Engineering Editorial Department of CEPRI.
