Abstract

Изобретение относитс  к порошковой металлургии. Цель изобретени  - увеличение скорости получени  порошков и интенсификаци  скалывани  осадка . Это обеспечиваетс  снабжением катода упругими струнами 3, нат нутыг ми между торцовыми стенками 1,2 и в радиальном направлении в плоскости торцов, а также выполнением торцовых стенок в виде эллипса при отношении длин большой и полуосей, равном 1,5-2. Применение плавак цих полых сферических электродных тел 4 обеспечивает при их взаимодействии с катодными струнами улучшение маесопереноса через объем электролита, увеличение площади поверхности катода, интенсификацию скалывани  порошка. Применение катода позвол ет по сравнению с известным увеличить скорость получе-.- ни  порошков в 5-6 раз. 1 з.п, ф-лы, 3 ил. i (ЛThe invention relates to powder metallurgy. The purpose of the invention is to increase the speed of obtaining powders and intensify spallation of sediment. This is ensured by supplying the cathode with elastic strings 3, tension between the end walls 1.2 and in the radial direction in the plane of the ends, as well as performing the end walls in the form of an ellipse with a ratio of the lengths of the major and semi-axes equal to 1.5-2. The use of floatable hollow spherical electrode bodies 4, when interacting with the cathode strings, provides improved maternal transfer through the volume of the electrolyte, an increase in the surface area of the cathode, and increased spallation of powder. The use of the cathode makes it possible, as compared with the known method, to increase the rate of obtaining —.- powders by 5-6 times. 1 з.п, ф-л, 3 Il. i (L
