Abstract

The ohmic (Joule) heating in an electrolysis cell during electrochemical deposition (ECD) with a binary electrolyte could be significant since the conductivity of the solution without supporting electrolyte is low. Here we report some results concerning the simulation of the thermal field due to ohmic heating in idealized 2D and 3D thin-layer ECD cells. The mathematical model is based on a Laplace-type equation for the electrical potential and a time-dependent equation for the heat conduction. The coupled equations system is solved using a finite element method. The numerical results are compared with experimental ones and a qualitative agreement is found..
