Abstract
Ternary Zn-Co-Ni alloys were deposited by electrochemical deposition technique on to steel substrates. The effect of bath
composition on the composition of the deposits, crystallographic structure, surface morphology and corrosion properties
were investigated. Polarization study revealed shift of potential towards positive direction in the presence of more nickel
content. SEM photomicrographs showed fine-grained deposit in the presence of nickel of 10 and 28 % in the film. All films
have the same structure, but with different crystallographic orientations. It is observed that Zn-Co-Ni alloy electrodeposition
is of anomalous type.
