PULSE-CYCLIC ELECTROCHEMICAL PROCESSING METHOD Russian patent published in 2019 - IPC B23H3/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to electrochemical methods of dimensional processing of metals and alloys and can be used for high-efficiency processing of hard-to-process metals and alloys with provision of modes of elimination of short circuits. Pulse-cyclic electrochemical treatment method involves treatment of part in electrolyte solution by voltage pulses, duration of which is longer than charging time of double electric layer, but shorter than short-circuit development time: t_char < t_pul < t_scd, where t_char is dual electric layer charging time; t_pul is duration of voltage pulse; t_scd is short circuit development time in electrolyte.

EFFECT: invention provides higher reliability of pulse-cyclic electrochemical processing.
