Abstract
The purpose of this study was to conduct metallographic studies of the composition of the charge obtained by the method of electrodispersion of lead brass waste in distilled water.Methods. Waste electrodispersion of lead brass brand LS58-3 was carried out on an experimental setup. Metallographic studies of charge samples from LS58-3 alloy waste were performed using the equipment of FGBOU VO SWGU and NRU BelGU: the shape, size and structure of charge particles, as well as its granulometric composition.Results. On the basis of the conducted experimental studies aimed at studying the composition, structure and properties of the charge obtained from the waste of the LS58-3 alloy in distilled water, the high efficiency of using the electrodispersion technology is shown, which provides, at low power costs, the production of new copper-lead powders suitable for industrial use. materials. It is noted that the powder materials obtained by electroerosion of lead brass waste of grade LS58-3 in distilled water have the following characteristics: the geometric shape of the charge particles is mainly spherical; particle sizes from 0.45 to 29.63 microns; the volume average particle diameter is 7.1 μm.Conclusion. The research carried out will allow for a gradual transition to advanced production technologies and materials through the use of progressive, environmentally friendly, low-tonnage and waste-free technology of electroerosive dispersion in the production of new copper-lead powder materials from LS58-3 alloy waste.
