| 摘要 |
The present invention relates to an electrochemical composite deposition machining method and apparatus using a laser light tube as an electrode. A full-beam pulse laser beam is converted to an annular hollow laser beam with zero light intensity at the center by a light beam modulating system; the annular laser is used to irradiate the expansion of plasma; a compression impact is generated on the electrochemical deposition within a non-solid light tube electrode. The deposition stress is removed, the cathode reaction gas is discharged, and the material density is improved; moreover, the deposition reaction can only occur in the center of the light beam where the laser energy is zero, thereby enabling electrochemical composite deposition machining, repairing and surface performance strengthening having high quality and good location-targeting. The present invention belongs to the field of rapid miniature machining and processing, and is suitable for the machining, repairing and surface performance strengthening of miniature high-performance metal parts. |
