Finite Elements Analysis of an Electrochemical Coating Process of an Irregularly Shaped Cathode with COMSOL Multiphysics®

The overall goal of this work is the use of COMSOL Multiphysics in the modelling of the current density distributions for the electrodeposition of Aluminum coatings from Ionic Liquids baths. The local current distribution is strongly dependent on the conductivity, on the distribution of concentrations and on the geometry of the galvanic cell, and, therefore, such a calculation can only be performed by the numerical solution of the Partial Differential Equations (PDE) governing the system. This work approach is to exploit computational techniques based on the wellknown Finite Elements Analysis (FEA) to obtain stationary and dynamical solutions of such a problem. The ability to predict the local current density on an electrode is crucial to eventually evidence portions where the deposition may be invalidated.
