ANALYSIS OF HEAT TRANSFER PROCESSES BETWEEN ELECTRODES IN CONDITIONS OF LIQUID PHASE PULSE ELECTRIC DISCHARGE FOR METAL TREATMENT BY THE BOW-CONTACT METHOD

摘要

In the paper there are presented results of analysis of heat transfer processes in an interelectrode space of a pulse electric discharge in water depending on working behaviors of the equipment in conditions of the bow-contact technology of metal treatment. There were determined such parameters of a power supply and technological conditions of the treatment that a duration of self-stabilizing electric discharges between the instrument and a work piece must be not longer than 1-1.5 ms. In that conditions a relative deterioration of the instrument is minimal (not exceed 15 percent).
