Abstract
In electroplating of ternary Zn-Ni-Fe alloy from the acidic chloride baths, the influence of iron codeposition on corrosion resistance and surface topography of the electrodeposits were investigated in comparison with Zn-Ni alloy deposits. It was found that the ternary Zn-Ni-Fe alloy showed better corrosion resistance in comparison with binary Zn-Ni alloy, even though both Zn-Ni-Fe and Zn-Ni deposits contained approximately the same nickel content. The best corrosion resistance, in 3% neutral sodium chloride solution, observed from the deposit having 16.74% nickel and 3.95% iron. The surface topography of the deposits was characterized by using scanning electron microscopy (SEM) in order to give more information about corrosion behaviors. It was found that the deposits with iron had finer grain size and more homogenous structure in contrast to that of Zn-Ni deposits.
