METHOD OF SERIES ELECTROLYTIC-PLASMA POLISHING OF BLISK BLADES OF TURBOMACHINES AND WORKING CAPACITY FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC C25F3/16 

FIELD: technological processes.

SUBSTANCE: invention relates to electrolytic-plasma polishing of articles from alloyed steels, high-melting and titanium alloys and can be used in turbomachinery construction during processing of blisk blades compressors of gas turbine engines to ensure the required operational properties of parts of turbomachines. Method includes dipping of treated blisk blades in electrolyte, which is in container, formation around processed surface of blades blisk steam-gas shell and ignition of discharge between treated surface of blisk blades and electrolyte. Container for electrolyte is a reservoir made from electrically insulating material with electrodes arranged in container reservoir pockets. Successively after finishing of the current blade polishing, the next blisk blade is lowered into the container and processing is performed till finishing of all blisk blades polishing. Working container is configured to be arranged in inter-blade space near the treated blade and providing coverage of the entire treated surface of the blisk blade.

EFFECT: higher quality of blisk blade processing.
