Abstract

This research attempts to optimize the parameters for DC plating of silver on silver alloy of two different
compositions namely 50% and 75% silver alloy. In the Silver –copper alloy, the surface morphology and composition
of the electro deposit are influenced by current density, silver concentration in the bath, applied current type and
addition of additive. It has been found that concentration of silver in silver alloy has an effect in weight electrodeposited over cathode in DC plating. The surface morphology is studied by taking SEM micrograph for the
two different compositions of silver alloy and grain size is measured using XRD analysis. Higher the purity of silver,
finer is the grain size. It has been observed that with the increase of silver in the sample, the amount of silver
deposited, hence the thickness of the deposit varies for the same current and voltage settings.
