Abstract: Disclosed are a device and a method for microelectrodeposition through a laser assisted flexible following tool electrode. Localization of electrodeposition and dimensional precision of members are enhanced by using the flexible following tool electrode to restrict a dispersion region of an electric field and a reaction region of electrodeposition, and a complex-shaped member can be deposited by controlling a motion path of the flexible following tool electrode. Since a laser has a high power density, introducing laser irradiation changes an electrode state in a radiated region, accelerates ion diffusion and electron transfer speeds, and increases a deposition rate, thus reducing defects such as pitting and cracking in a deposit, enhancing deposition quality, and achieving fabrication of a micro-part by a synergistic action of both electrochemical energy and laser energy.

Abstract: A device for insulating a cathode surface in electrochemical machining is provided. The cathode surface insulation device is characterized in that super-hydrophobic micro-structures are prepared in regions to be insulated on the cathode surface, so as to realize selective insulation of the surface of the tool cathode, and thereby achieve objects of constraining an electrical field in the processing area, reducing stray corrosion and side surface taper, and improving processing efficiency and accuracy.
