Description

technical field [0001] The invention relates to the field of micro-rapid prototyping in manufacturing technology, in particular to an electrochemical composite deposition manufacturing method and device for laser light tube electrodes, which are suitable for processing, repairing and surface performance enhancement of micro-miniature high-performance metal parts. Background technique [0002] Both laser processing and electrochemical processing belong to special processing methods. The two processing methods have their own characteristics. Laser processing uses high-energy beams as processing energy. When it is focused on the surface of the workpiece through optical transmission, it will generate unique light, heat, force and other non-linear effects. Electrochemical machining is to use a circuit to transmit current to both ends of the electrode. The electrodeposition solution is used as the medium between the electrodes, and finally an electrochemical reaction occurs at the...

AI Technical Summary

Problems solved by technology

However, the recombination efficiency of laser energy and electrochemical reaction is not ideal. The thermal effect of laser will vaporize the solution at the deposition site to form an anhydrous zone. The expansion and expansion of the body will push the solution outward, which is not conducive to the localized deposition of metal ions in the processing area.
