Laser-assisted flexible follow-up tool electrode fine electrodeposition device and method

Abstract

The invention discloses a laser-assisted flexible follow-up tool electrode fine electrodeposition device and method, and relates to the technical field of localized fine electrodeposition. According to the device and method, a flexible follow-up tool electrode is used for limiting an electric-field dispersion region and an electrodeposition reaction region, so that the fixed-area performance of electrodeposition and the dimensional accuracy of a component are improved; and a component with a complex shape can be deposited by controlling a movement path of the flexible follow-up tool electrode.Due to the fact that a laser has a high power density, laser irradiation is introduced to change the electrode state of an irradiation area, the ion diffusion speed and electron transfer speed are accelerated, the deposition rate is increased, the defects such as hemp holes and cracks in the deposition body are reduced, and the deposition quality is improved. The manufacturing of fine parts is realized through the combined action of two kinds of energy of electrochemistry and lasers. The method is mainly used for manufacturing the fine parts and can effectively improve the precision of electrochemical deposition and the forming precision of the parts.

Description

technical field [0001] The invention mainly relates to the technical field of localized micro-electrodeposition, in particular to a method and device for micro-electrodeposition of laser-assisted flexible follow-up tool electrodes, which are suitable for processing and manufacturing micro-metal parts. Background technique [0002] The micro-electrodeposition technology is based on the principle of electrochemistry. The metal ions in the solution move to the cathode to obtain electrons to undergo a reduction reaction. The metal ions are continuously reduced to accumulate and accumulate materials on the surface of the cathode in the form of atoms and molecules, so micro / nano Level additive manufacturing has great room for development in the field of micro-nano manufacturing. Laser processing is a non-contact processing method, which has the advantages of high energy density, high efficiency, and good flexibility. Laser irradiation is introduced to enhance micro-area stirring, ...
