A simple theoretical approach treating the kinetics of phase formation at constantly increasing supersaturation is developed. The process of electrolytic nucleation in galvanostatic regime i.e. at time changing cathodic overpotential is analyzed in terms of this formalism. It is found that the atomistic model of nucleation has to be applied in order to describe quantitatively the process of electrolytic phase formation.
