METHOD OF PRODUCING METALLIC NANOPOWDER FROM LEAD BRONZE WASTES IN DISTILLED WATER

摘要

FIELD: physics.;SUBSTANCE: invention relates to production of nanopowders from lead bronze wastes, which can be used for application of wear-resistant, antifriction, corrosion-resistant and antiscoring coatings. Waste of lead bronze is subjected to electro-erosion dispersion in distilled water at pulse repetition rate 95…105 Hz, voltage at electrodes 190…200 V and capacity of capacitors 65.5 mcF, followed by separation of nanosized particles from large-size centrifuging solution.;EFFECT: obtaining nanopowders from wastes with low power consumption and ecological purity of the process.;1 cl, 6 dwg, 3 ex
