Abstract:

In this paper, the theory of fractal was introduced to investigate the dynamics of dendrite growth during jet electrodeposition and to further control the growth of dendrites. In the investigation, the modified diffusion-limited aggregation （DLA） model was adopted and the Microsoft Visual C ＋ ＋ 6.0 programming was performed to simu- late the morphology of the two-dimension dentrite cluster obtained by the jet electrodeposition with parallel plate electrode. Moreover, by using parallel Ni plate as the anode and graphite plate as the cathode, two-dimension Ni dendrites were manufactured by a self-designed jet electrodeposition system to verify the simulated results. It is found that the Ni dendrites possess the character of fractals and are similar to those simulated by the DLA model, meaning that the proposed model is helpful to the experimental investigation of jet electrodeposition with parallel plate electrode.
