Abstract

Pulsed electro deposition of silver alloy is aimed at the improvement of some properties like finer grain size, hardness, anti-tarnishing, lower porosity, improvement in surface property. The pulsed electro deposition of silver alloy has been analyzed from an alkaline cyanide bath with brightener. Pulse duty cycles of 20% to 80%, at frequencies 10 Hz, 25 Hz, 50 Hz and 100 Hz with peak current densities ranging from 1 A/dm2 to 9.3 A/dm2 are employed. The influences of pulse duty cycle, peak current density and pulse frequency on the thickness, hardness of silver deposit, and current efficiency of the plating process are studied. Good quality deposits (less porosity and fine grains) can be obtained at lower peak current density and higher duty cycle.
