Simulation of nucleation and growth processes. Application to nickel electrocrystallization in aqueous solutions

A comprehensive approach of the mechanisms of electrochemical processes inv olving nucleation and crystal growth is described. The study is based on th e use of transient electrochemical techniques which prove to be useful in d etermining the kinetics of reaction steps. Fundamental equations are derive d to obtain a precise knowledge of transport and growth processes in solids . Since algebraic solutions are not available, quantitative results are obt ained by numerical calculations. An application to the study of nickel depo sition in acidic solutions is given.
