| Summary: | This research has been performed to understand the impact
of the combination of nickel anions of sulfate (SO4
2-
), and chloride (Cl-
) in the
solution towards nickel deposition. The evaluation was performed for the
voltage, weight, and efficiency. The electroplating of nickel was performed
by chemical cleaning of the specimen surface, nickel deposition in the nickel
solution under specific current density, and post-cleaning to remove the
residual solution. The nickel solution was consist of sulfate, and chloride
anions compared with nickel sulfate solution only. The result showed that
the presence of chloride anions in a sulfate solution lowered the voltage,
increased the weight of nickel deposition, and increased efficiency compared
with the impact on sulfate solution only. The voltage of a solution consisting
of chloride and sulfate decreased by more than 30%, compared with sulfate
solution only. The weight of nickel deposited on the specimen surface
increased clearly. As the number of chloride anions increased, the nickel
deposition increased linearly. Interestingly, the highest nickel weight was
achieved at a low chloride anion concentration. The heaviest nickel
deposited is 0.7 g was achieved under 0.07 A/cm2 and 15 g/l chloride anions.
The nickel deposition efficiency in the combination of sulfate and chloride anions is always higher than 80% compared with nickel sulfate solution only. |
