Electrodeposition of ternary nickel-iron-molybdenum alloys from an acetate bath

Ternary nickel-iron-molybdenum alloys containing 0.5–8.5% molybdenum, 18–48% iron and balance nickel were electrodeposited from an acetate bath under a variety of conditions. Satisfactory deposits were obtained from the bath containing 0.3394 M nickel acetate, 0.02878 M ferrous sulphate, 0.0015 M sodium molybdate at current density 2.0 A dm^–2, pH 5.0 and temperature 20°C without agitation for plating times up to 30min. The alloy deposits were examined for their crystal structure by X-ray diffraction and microstructure by metallography.Dedicated in honour of the late Dr D. Singh, Reader in Chemistry, Banaras Hindu University.
