Abstract

This research attempt is made to study the effect of base metal composition in pulse plating of silver over silver alloy.
The effect of pulse parameters due to the electro deposition of silver over 50% silver alloy is studied and the results are
compared with the results obtained from the study of the effect of pulse parameters because of the electro deposition of
75% silver alloy. The surfaces are characterized by scanning electron microscopy and X-ray techniques. Higher the
purity of silver, finer is the grain size. It is also evident that 75% silver alloy has more corrosion resistant than 50%
silver alloy. It is suggested that the properties are improved in pulse plating if the concentration of silver in silver copper
alloy is more.
