Using point metal Ni as anode and circular graphiteas cathode, two- dimensional dendrite of Ni was manufactured by jet-electrodeposition to test the simulation. The re- sult shows that the dendriteof Nihasthe character of fractal, it is similar to the resultsof simulation. The model mentioned above gives a very accurate depiction to the growth process of dendrite in elec- trodeposition and would be helpfulto direct the experimentation of dendritefractal growth.
