镀锌的

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 .
