METHOD OF PROCESSING PART SURFACE BY ARC DISCHARGE IN VACUUM AND DEVICE TO THIS END Russian patent published in 2012 - IPC C23F4/00 B23H9/00 C23C14/02 

FIELD: machine building.

SUBSTANCE: proposed method comprises exciting the discharge, processing the surface by vacuum arc cathode spots and displacing them along processing area. Note here that arc cathode area is displaced along processing area by varying current strength via negative potential current leads connected to two and more points of processed surface with concurrent continuous or discrete relative displacement of positive electrode and processed surface. Proposed device comprises arc supply source, positive electrode and processed article placed in vacuum that makes cathode. Note here that negative potential current leads are connected to processed surface at two and more points via current controller.

EFFECT: higher surface quality, simplified process.
