Electrodeposition of Nickel from Perchlorate Based Electrolytes

SUMMARY

Nickel is usually electrodeposited from the Watts bath. Other baths like sulphamate and fluoborate are also of industrial importance but are used less commonly. Perchlorate solutions, though examined to some extent in the case of cadmium and lead deposition, have not been experimented upon for deposition of nickel. In this paper certain operational data on Perchlorate nickel deposition are presented. As a consequence, the following bath composition is recommended: Nickel 29.2 g/l, perchloric acid 201.0 g/l, ammonium chloride 60–120 g/l, pH 5.5-6.8. The useful current density is 1–5 A/dm² and optimum temperature 50°C.
