Experimental Research and Simulation of Laminated Templates Electro-deposition in Manufacturing Metal Part
Laminated templates electro-deposition (LTE) is a new manufacturing technique aimed at a highly precise and low-cost fabrication of metallic structures through a number of planar template-patterned depositing. Based on the initial experiments, the ability to control deposit surface non-uniformity in each planar depositing is known as a key to this technique and correspondingly a three-dimensional simulation for electrical field has been modeled using the finite-element method in line with real experimental conditions. The mapped contour of simulating proved the variedly distributed electrical field on cathode and basically match with the experimental results. Also in this paper, three groups of LTE test respectively powered by direct current , pulse and double-pulse current are introduced and assessed in term of their effect to improve uniformity. By comparison, pulse application, especially double-pulse offered a better deposit quality with optimized parameters including pulse width, frequency,working time and off time. Theoretical explanation is proposed about the effect of pulse-reverse current in its reducing surface roughness . A bulk of 10-15layers copper parts , section size 20mm×20mm and 4-6mm thick ,were produced using the improved experimental conditions.
