Document Type and Number:
WIPO Patent Application WO/2023/284431
Kind Code:
A1
Abstract:
The present invention relates to the field of special processing. Disclosed are a method and apparatus for implementing localized electrodeposition induced by using laser irradiation on the back of a thin-walled part. In the method, a part to be repaired is repaired under the combined action of a laser and an electrochemical reaction; and a tool anode is placed on the back of the part, the tool anode and the part keep apart by a certain clearance, and a laser beam is focused on the outer surface of the part to locally repair the back. In light of the problem that inner wall coatings of tubular, box and other parts fall off, malfunction, and are difficult to repair, the present invention utilizes high thermal conductivity characteristics of a workpiece, and synergizes a laser thermal effect with electrochemical deposition to achieve the localized coating repair on the back of the workpiece, and no electrodeposition reaction occurs in the remaining regions that do not need to be repaired. The operation process is simple, plating solution costs are greatly reduced, and the problem of the difficulty of repairing the inner wall coating of the thin-walled part after falling off is solved.
