Potentiostatic Current Transients during the Diffusion-Controlled Growth of a New Phase

Аннотация

The problem of a mathematical description of the formation of an electrode deposit layer according to the mechanism of nucleation–growth–overlapping of new-phase 3D clusters and their diffusion zones is considered. The characteristics of potentiostatic current transients are analyzed. Expressions for calculating the nucleation parameters and the diffusion coefficient of deposited ions are obtained.
