A Mathematical Model of Pulse Plating on a Rotating Disk Electrode

Document Type



A galvanostatic pulse plating model is presented for the electrodeposition of an alloy on a rotating disk electrode. This model is used to simulate the electrodeposition of nickel/chrome alloys. The mass transport equations used in the model include the effects of diffusion, migration and convection; and the electrode kinetics are described by the Butler-Volmer equation. It is predicted that the effect of ionic migration is significant and therefore should be included in models of pulse plating.
