See Lowenheim, Frederick A. "Electroplating. Fundamentals of Surface Finishing," McGraw-Hill Book Co., New York, 1978. pp.180-182. (ISBN: 0-07-038836-9)

It seems that you may be missing an additive or the pH might be too high.



RE: zinc electroplating

i am trying to have free download of the book (but i cant). but what kind of additive should i use and the pH should be what?

RE: zinc electroplating

Can you provide more information about the plating conditions? Such as temperature, pressure, concentrations of components, pH, plating voltage, etc.

RE: zinc electroplating

concentration 26gm ZnSO4 with 200gm water
temperature room temperature around 23C
pressure atmospheric pressure
plating voltage 20V
