FIELD: metallurgy.
SUBSTANCE: method includes igniting a discharge between a workpiece manufactured by fusing fine particles of metals or alloys and a cathode by applying a positive potential to the article, the workpiece being fixed on a conductive suspension, immersed in an electrolyte bath containing a cathode in the form of a conductive plate, and rotate, a voltage in the range of 100 ≤ U ≤ 1000 V, the discharge current is in the range of 0.015 ≤ I ≤ 250 A and process the product for at least 15 seconds, with the electrolyte being a solution with a hydrogen index in the range of 2 ≤ pH ≤ 11.
EFFECT: providing processing of external, internal and porous areas of the surface of products of complex geometric shape, increasing the degree of purification, roughness class and surface hardness of the product.
