The effect of an applied voltage on the electrochemical deposition is investigatedwith the use of computer simulation. The model equations are expressed in terms ofcoupled diffusion fields; the one is the concentration field of tons, and the other is theelectric potential field. An important dimensionless parameter is introduced todescribe the strength of applied voltage. It is found that the morphology of the aggregate crosses over from DLA fractal to the dense aggregate when the parameter is increased. The mechanism of the aggregation based on this model seems to be morerealistic in comparison with experiments on the electrochemicai deposition ratherthan a diffusion-limited aggregation model with drifting random walk particles.
