NUMERICAL SIMULATION OF METAL COATING PROCESSES USING ELECTRICAL DISCHARGE DEPOSITION

Ana-Cristina IUGA, Liviu-Daniel GHICULESCU

Abstract


This study investigates the numerical simulation of microstructure deposition using three distinct electrode materials, utilizing COMSOL Multiphysics software. The electric discharge deposition (EDD) process serves as an advanced additive manufacturing technique for creating metal structures. This method relies on the high wear rate of the tool electrode, operating as the reverse of electrical discharge machining, to facilitate metal deposition onto a substrate. Additionally, the effect of tool electrode rotation was examined to determine its influence on material distribution and deposition uniformity. The research also examines the impact of a magnetic field on the EDD process for three electrode materials to enhance deposition quality. A finite element model was developed with parameterized working conditions to analyze their effect on the deposition process.
