In order to reveal the laser thermal-mechanical effect on electrochemical deposition further, a laser electrochemical composite deposition system was constructed, and the system was analyzed and verified. Specimens were prepared in the exposure area by laser round scanning, and mechanical effect and thermal effect was developed in the processing. Finally scanning electron microscope was used to observe surface morphologies of specimens. The results show that laser thermo-mechanical effect could speed up the reduction reaction of metal ions, promote nucleation and grain refinement. The deposition rate is enhanced at 0.198mg/min when laser energy is 0.2mJ(20kHz), and tensile strength is strengthened at 256.38MPa when laser energy is 0.4mJ (20kHz). The results are useful for the development of electrochemical machining technology later.
