Information × Registration Number 0212U001723, 0110U002560 , R & D reports Title Development of a new method of electrodischarge synthesis of compositional powders containing carbon and metals, and pilot equipment for their spark-plasma plugging. popup.stage_title Head Suzonenko Olga Mukolayivna, Registration Date 02-03-2012 Organization Institute of Pulse Research and Engineering popup.description2 For the first time on the basis of research of regularity of the processes of phase- and structure formation of composition powders of type WC, TiC with a metal bond (Со, Fe,..) at the high-voltage electric discharge in a hydrocarbonic liquid, results of X-ray-phase and micro-X-ray-spectrum analyses, the new method of synthesis of composition powders is developed. Regularity of dependence of reserved energy (from 0.25 to 4 kJ), integral energy (from 0.8 to 4 МJ) and the rate of current rise (from 13 to 31 GA/s) on the intensity of powder interaction Fe-C; Ti - C; Fe-Ti; Co-C in the course of the electric discharge. The thermodynamic analysis is carried out, conditions are theoretically proved and parametres at which chemical reactions in system "powders - hydrocarbonic liquid" are possible are determined. The electrodischarge method and the device for metal carbides electrodischarge synthesis of a transitive group is developed. For the first time in Ukraine work on making of a new generation of power-generating equipment for plasma-spark sintering of disperse composites. Physical modelling is done of separate circuit designs and knots of the generator of plasma-spark sintering - the high-frequency inverter, the high-frequency rectifier, the high-frequency reducing transformer, elements of the circuit design.
