Computer simulation of potentiostatic current-time transients for nickel electrocrystallization
Résumé
A stepwise computer model is presented for the potentiostatic current-time transient response of hemispherical centres nucleation and the radial growth mechanism. A general time-dependent nucleation law is considered and a particular attention is devoted to the effects of the ohmic drop on the transient responses and onto the growing centres number. Computed data are compared to experimental transient curves and to TEM micrographs obtained in the case of nickel electrocrystallization onto vitreous carbon.
