Electromechanical systems, which provide electrical power and data

connection between moving terminals require high conduction and erosion

resistant surfaces. Transfers of electrical power and data are accomplished

by the contact of drum and brush wires. The simultaneous electrochemical

deposition of desired Au-Ag-Cu alloy compositions, which can be used to

coat the brush wires, was investigated in this study. In the scope of the study,

the static potential and cyclic voltammetry behaviors of gold, silver and

copper cyanide plating baths, as well as the mixtures of binary and ternary

baths were investigated to obtain suitable amount of KCN and working

potential values. SEM and EDS analyses were conducted in the

characterization of coated samples.
