SURFACE PROCESSING BY ARC DISCHARGE IN VACUUM

摘要

FIELD: metallurgy.SUBSTANCE: arc discharge cathode spots are initiated at processed surface, arc discharge being initiated between anode and cathode in the mode of voltage-current characteristic of increasing section, said cathode being a processed surface. Region of cathode spot location on processed surface is localised and processed surface is shifted by anode displacement. Anode with current-collecting surface area smaller than that of cathode is used and placed at the distance from cathode that ensures a positive anode voltage drop.EFFECT: stabilised cathode spots on processed surface, fast surface cleaning and higher surface quality.2 dwg
