To control the surface quality of gold films electrodeposited on tungsten helix, the effects of current density, electrolytic temperature and deposition time on the electrodeposits were studied. The morphology of gold films was evaluated by means of scanning electron microscope (SEM). The results indicate that current density affects the grain size of the film. When electrodepositing at higher current density, the surface defects such as burring and sponge feature the gold film. The electrolytic temperature causes poorer stability of electrolytic solution and deposition quality. In addition, the variation of deposition time results in different electrodeposits quality. With increasing the deposition time, the edge effect is serious. The proper deposition time is about 1.5 h
