METHOD FOR PRODUCING LEAD-BRASS POWDERS FROM WASTES OF LS58-3 ALLOY IN DISTILLED WATER Russian patent published in 2023 - IPC B22F9/14 B22F1/65 

Abstract RU 2795306 C1

FIELD: powder metallurgy.

SUBSTANCE: production of metal lead-brass powders. It can be used for the manufacture of friction parts, for small parts in microengineering, for spraying decorative coatings. Lead-brass powder is obtained by electroerosive dispersion of LS58-3 grade alloy waste in distilled water at an electrode voltage of 150–200 V, a condenser capacity of 50–55 μF, and a pulse repetition rate of 50–100 Hz.

EFFECT: obtaining a powder of the correct spherical shape with a uniform distribution of alloying elements, ensuring the environmental cleanliness of the process.
