Process detection and laser electrochemical composite deposition

Abstract

A detection system equipped with a hydrophone and an infrared imaging device was developed to determine the thermal and mechanical effects of a laser on electrochemical composite deposition. Scanning electron microscopy was performed to observe the surface and cross-sectional morphology. Experimental results show that the mechanical and thermal effects of a laser get more pronounced when a laser energy is increasing, which is more evident in the CuSO₄ electrolyte. Those effects can result in increased deposition rates and refined grains, which is important for the electrochemical composite processing.
