Abstract:The electrodeposition of zinc from zinc chloride-1-ethyl-3-methylimidazolium chloride molten salt was adopt to study the process of the cathode reaction. The electrodeposition was carried out with direct current and impulse current. The factors influencing the coating were studied. The result indicate that: the electrodeposition of zinc on nickel and tungsten substrates involves instantaneous three-dimensional nucleation. The coating is the best when the current density is 4mA/cm2 and the temperature is 80 ℃. The coating by the method of the impulse electrodeposition is better than the direct current electrodeposition. Especially when f is 100Hz, ton/toff is 2/8 and J is 8mA/cm2, the coating is clean and uniformity. The crystal size is nearly 0.3μ m .
