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.
