Resumen:
AbstractIn this work we study the effects of viscosity
variations in thin-layer electrochemical deposition (ECD)
under galvanostatic conditions through experimental
measurements and theoretical modeling. The theoretical model,
written in terms of dimensionless quantities, describes diffusive,
migratory and convective ion transport in a fluid under
galvanostatic conditions. Experiments reveal that as viscosity
increases, convection decreases when the cell resistance
remains constant. Our numerical model predicts that as
viscosity increases, electroconvection becomes less relevant and
concentration and convective fronts slow down. The time
scaling of this phenomenon is studied and compared to
previously reported low viscosity solution studies.
