Electrode position of zinc-nickel alloy

Studies on the electrodeposition of zinc-iron group alloys are of academic and technological interest. The anomalous codeposition and enhanced corrosion protection of zinc-nickel alloy deposits make the search for newer plating bath formulations. Zinc and nickel were codeposited from sulphamate bath and 82 per cent zinc was obtained in the deposit. The suphamate bath developed offered 100 per cent current efficiency with 24 per cent throwing power.
