| Dendritic growth on metal electrodeposition process is a more importance problem, When making metal use the electrolytic process, The Hendritic growth always the reason what make the process can not normal proceed. Study the process about the dendritic growth and its morphology can make one understand this growth process very well, it also can help make sure the anfractuous industrial process make good play, and help produce high-quality products. In addition, because the result was often anisotropic and inhomogeneous and its complex forms are not well understood, the growth of dendritic crystal on electrodeposited metals has attracted scientific interest for a long time. Yet the full nonline problem is difficult to solve by use of traditional Euclidean geometry method, even the numerical solution cannot be got, so it puzzled researcher nearly half century.Today, computer be used to simulation various growth process, the major advantage about computer simulation is, when completed a program, one can setting or change the parameters at his option, and computer can automatic performance, accomplish a great deal miscellaneous task, and finally, computer will give one result which people want or beaten all. The computer simulation about has more import applied cost. Combine the basic theory about fractal and computer simulation, people solved some questions that classical electrochemistry never considered, so people can more objective understand the process of dendritic growth, lead more tenuously conclusion, this must give the question which dendritic growth more help.In this paper, The electrochemical growth of agglomeration is studied by combination of fractal and electrodeposition, by means of modify the DLA model, realized the simulation about the growth process of electrodeposition which used point electrode or parallel plate electrode as cathode, compare and analyze the difference analog result by the way of fractal dimension. And then, experimental investigations the two-dimension growth process of electrodeposition metal copper and zinc, The current time graphs were got and the fractal dimension and macroscopic morphology under various experimental conditions were observed and analyzed. The results show:1. The simulation of dendritic growth process on point-like cathode shown, as the rate of migration about particles increase, the form aggregation has a trend forminopen growth to dense growth. For use the parallel plate electrode as cathode, the change of particles migration rate, there is not clearly change on the simulation aggregation can be found. But both for point-like cathode and parallel plate electrode, the fractal dimension will enhance with the rate of migration about particles increase.2. When the kernel is changed to circle N square or line and so on, the morphology about simulation aggregation are different, but their fractal dimensions are similar.3 . During the different stage of electrical deposition procedure discovered, that during the initial stage of electrical deposition, with the tune prolong, the fractal dimension of formed aggregation of deposited metal increase, while the fractal dimension of aggregation gained by the simulation to dot electrode is waving at a invariableness number; and to the parallel board electrode, its fractal dimension have a tiny increasing potential.4 . On the experiment of copper electrodeposition , the current through experimental apparatus will increase with the time of electrodepositing, and the higher the applied voltage, the higher concentration of the copper sulfate, the faster the current increase.5 . On the process of copper electrodeposition experiment, it was found that the hydrogen evolved from cathode, but on the process of zinc electrodeposition experiment, there was not hydrogen evolved. In our scope of experiment, the change of applied voltage will affect the fractal dimension for both copper and zinc-electrodeposited aggregation. But the change of fractal dimension for copper is irregular. For zinc...
