The influences of anode size, jetting speed, NiSO4 concentration and experiment temperature on the growth property of dendrite growth and fractal dimension were investigated. The results show that the dendrite of metal Ni obtained in jet-electrodeposition with point anode is also fractal growth. The fractal dimension of dendrite increases with increasing anode size. With increasing jetting speed, the growing points at the bottom of dendrite increase significantly and the morphology at the top becomes denser when the je
