✦ Synopsis
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.
Es wird ein einfacher theoretischer Formalismus entwickelt, welcher es gestattet, Phasenbildungsprozesse bei stetig anwachsender fjbersattigung zu beschreiben. Elektrolytische Keimbildung unter galvanostatischen Bedingungen -im Regime steigender kathodischer fjberspannungwird im Rahmen dieses Formalismus betrachtet. Es wird gezeigt, daD zur quantitativen Beschreibung der elektrolytischen Keimbildung das atomistische Modell angewendet werden muD.
