Abstract

The invention discloses a laser and electro-deposition combined machining device and method, and relates to the technical field of combined non-traditional machining. A transparent conductive materialis used as an auxiliary anode to directly face a cathode workpiece to realize uniform distribution of an electric field on the surface of a cathode plate; when laser-induced electro-deposition machining is carried out, a three-dimensional fine part is prepared through the principle that laser focuses move upwards layer by layer and sediments are continuously superposed; and when laser enhanced electro-deposition machining is carried out, a laser focus carries out overall or local scanning on the surface of a deposition layer, so that the performance of the deposition layer is improved, or a surface structure is prepared while the deposition layer grows. The device and the method are simple, and are suitable for preparing fine complex parts and high-performance surface coatings.

Description

technical field [0001] The invention mainly relates to the technical field of composite special processing, in particular to a device and method for composite processing using laser electrodeposition, which is suitable for the preparation of fine and complex parts and high-performance surface coatings. Background technique [0002] Electrodeposition technology is based on the principle of electrochemistry, that is, a coating processing technology that generates a metal layer on the surface of metal materials or semiconductor materials through the reduction reaction of metal ions near the cathode of the deposition pool and the electrocrystallization process. Electrodeposition technology, as a technology for surface modification or preparation of metals with specific components and properties, has been widely used in the field of micro-nano manufacturing. However, the traditional micro-electrodeposition technology has poor localization, low deposition efficiency, and poor bond...
