In the work scientific and applicative principles of LS58-3 (CuZn39Pb3) grade brass waste processing technology into powders suitable for industrial application are realized. The purpose of the work was to study the physicochemical properties of the lead brass charge obtained by electroerosion in isopropyl alcohol under the optimal dispersion regimes. Grinding of alloy waste to microparticles was carried out on a special patented unit. Optimization of lead brass electrodispersing process was carried out by setting up a full factor experiment. The validation of composition and properties of the obtained powders was carried out using modern intercomplementary methods of physical materials science. It has been experimentally established that the composition, structure and properties of the charge dispersed by electrical erosion of brass LS58-3 are influenced by the chemical composition of the dielectric fluid, as well as dispersion modes. The particles of the resulting charge have a given complex of properties and can be used by various methods of powder metallurgy. The results of the conducted researches allow to recommend the use of the obtained powder as an initial raw material for obtaining alloy blanks and to expand the area of their practical application. Economic efficiency from the use of electroerosion powders is due to the use of waste and low energy-intensive technology for their production.

The work was carried out within the framework of implementation of the development program FSBEI HE “Southwest State University” of the project “Prioritet-2030”.
