Abstract: Based on the diffusion-limited aggregation(DLA) model,the parallel plate electrode jet-electrodeposition medel was built,and the growth process of jet-electrodeposition with parallel plate electrode was successfully simulated.Using parallel plate Ni as anode and graphite plate as cathode,the two-dimensional dendrites of Ni were manufactured,the simulated results were compared with the test results.The results show that the dendrites of Ni obtained on graphite plates were similar to the results of numerical simulation.It was feasible that using the model to simulate dendrite fractal growth in jet-electrodeposition with parallel plate electrode.
