METHOD OF CREATING AN IDENTIFICATION MARK AND A TOOL FOR ELECTROCHEMICAL PROCESSING OF AN IDENTIFICATION MARK Russian patent published in 2018 - IPC G06K1/12 B23H5/00 B23H9/06 

FIELD: technological processes.

SUBSTANCE: invention relates to the identification of material resources made of electrically conductive materials. Method includes applying to the electrically conductive object a coordinate grid with an identification number and an individual unique matrix obtained by electrochemical interference between the object and an electrode connected to a low-voltage current source with the introduction of laser radiation through a glass substrate and a semitranslucent metal film into the interelectrode gap. Laser radiation is introduced into the interelectrode gap through a corner reflector freely fixed above the metal film and located in the electrolyte stream above the metal film, the electrolyte stream in front of the corner reflector is further turbulized. Tool for electrochemical processing is also provided that creates an identification mark on an electrically conductive object using laser radiation stochastically irradiating the surface of the object in a wide range without the use of a random number generator.

EFFECT: method for creating an identification mark and a tool for electrochemical processing of the identification mark are proposed.
