MODELING AND SIMULATION OF ELECTRICAL DISCHARGE DEPOSITION OF DIFFERENT MATERIALS

Abstract

This paper deals with numerical simulation of the deposition of microstructures with two different electrode materials using a dedicated software, COMSOL Multiphysics. An electric discharge deposition process (EDD) can be used to fabricate various metal structures, using a new type of additive technique. The metal is deposited in this process by using the tool electrode's high wear rate as an inverse process of electrical discharge machining. An analysis of the effect of the magnetic field at EDD on two electrodes materials, copper, and tungsten over the substrate was achieved for the purpose of improving the quality of the material deposition. The finite element modeling was parameterized, considering above all the working parameters to determine their influence on the deposition process of the studied materials of electrodes.
