Analytical Methods. In addition copper has a high plating efficiency while being among the least expensive metals in stable supply. Silver has been applied since late 1800s on electrical switchgear and other components that pass electrical current. Silver plating of copper or copper alloys is a highly functional finish for transferring heat and electricity utilized across a wide breath of industries. Pulse Electroplating of Copper Film: A Study of Process and Microstructure Zhang et al. conductivity of copper, and the ease of mechanical working and brazing. Experiment 8: Copper Electroplating and Faraday’s Law 1 Purpose: An electrochemical cell is constructed to determine the efficiency of copper electroplating. The chemical treatment was planned to be replaced by physico-chemical process like adsorption.
