STUDY OF THE ELECTROSPARK DISPERSION PROCESS OF MATERIALS TO OBTAIN NANO-SIZED COMPONENTS OF PROMISING POWDER COMPOSITIONS FOR ADDITIVE TECHNOLOGIES

A laboratory electric spark machine was developed, that makes it possible to create an overvoltage at the inter¬electrode gap between the dispersible electrodes. The possibility of obtaining nanopowders of conductive mate¬rials by the method of electrospark erosion under the con¬ditions of a significant overvoltage of the discharge gap is shown. The prospects of obtaining powder materials in low tonnage volumes for additive technologies with high economic effectiveness are shown.
