Numerical Simulation of the anomalous electrodeposition of Nickel-Iron alloy on rotating disk electrode

Abstract

Electrodeposition was originally used for the preparation of metallic mirrors and corrosion resistant surfaces. In this paper, we study a stationary one dimensional system modelling nickel-iron alloy electrodeposition. This system takes into consideration the following phenomena: dissociation, diffusion, electromigration, convection and deposition of multiple ion species. In this work, we present the finite element discretization of the main model supported with a numerical algorithm to effectively handle the nonlinearities. We compare the obtained numerical result with experimental data reported in the literature and show that our simulation method can predict the characteristic features of the Nickel-Iron system.
