Abstract:
Cu-Ni alloy films were synthesized by pulsed electrodeposition process from a
citrate bath without additives at 35°C and pH of 7. The effect of current density (40, 60, 90
and 110 mA/cm2) on the composition and surface morphology of deposited films was
investigated by EDX and SEM, respectively. The results showed that the particle size
increased from 5.97 to 15.45 μm as the current density increased from 60 to 90 mA/cm2,
while further increase in current density had no significant effect. The surface morphologies
of the Cu-Ni alloy films exhibited a cauliflower-like appearance and crack-free characteristics
at both low and high current densities. The CuNi alloy films have a stoichiometry of
Cu0.86Ni0.14, Cu0.90Ni0.10, Cu0.80Ni0.20, and Cu0.88Ni0.12 that are obtained at 40, 60, 90 and 110
mA/cm2, respectively. It was found that nickel content in the deposited film increased as
the current density increased from 60 to 90 mA/cm2 because copper and nickel codeposition
is of the regular type. However, an interesting finding is that the content of nickel decreased
when the current density increased from 40 to 60 mA/cm2 and 90 to 110 mA/cm2. This
might be caused by a nickel dealloying in the electrodeposition process.
