HAND TOOL - ELECTRODE FOR ELECTROCHEMICAL POLISHING OF METALS Russian patent published in 2013 - IPC C25F7/00 C25F3/16 

FIELD: chemistry.

SUBSTANCE: hand tool has a housing made from dielectric material in which there is an electrode which is connected to the negative terminal of a direct current source, a flexible tube for continuously feeding electrolyte into the gap between the electrode and the processed article which is connected to the positive terminal of the direct current source. The electrode consists of a fixed part and a removable part in form of a nozzle with openings. The housing and the fixed part of the electrode are in form of hollow cylinders. The fixed part of the electrode is pressed into the housing with formation of a protrusion for mounting the nozzle, wherein one part of the openings in the nozzle is used to pass the electrolyte and the other is used to mount means of forming said gap, which are in form of remote supports and are made from dielectric material, each consisting of two parts in form of a cylindrical part which is pressed into the nozzle, and a hemispherical part. The nozzles can be in form of a hemisphere, a rectangular prism, a cone or a cylinder.

EFFECT: invention improves the quality of processing metal surfaces while maintaining geometric parameters of articles obtained before electrochemical polishing.
