| Description |
Zinc electrodeposits offer protection to steel against atmospheric corrosion both by galvanic and
shielding effects. The cyanide process for zinc electrodeposition is increasingly being replaced
by chloride and many other non-cyanide formulations. The search for a better zinc plating
electrolyte is therefore a continuing process. In this paper the authors present details of zinc
plating from an acetate electrolyte together with the deposit properties. The addition of
thiaminehydrochloride to the plating bath improves the surface morphology of zinc electrodeposits.
The X-ray diffraction data obtained for electrodeposited zinc showed it to be
polycrystalline in nature with an hexagonal structure. Analysis by scanning electron microscopy
demonstrated a uniform and pinhole-free surface.
