A non-cyanide brass plating bath

Abstract

Brass electrodeposits are used for decorative applications and for promotion of adhesion of rubber to steel and other metals. Brass coatings, because of their lubricity, are applied on rods and wires which are further subjected to joining into thinner gauge. Brass deposits are generally obtained from cyanide electrolytes. With a view to exploring the usefulness of a non-cyanide formulation, solutions with nitrillo-triacetate complexes were experimented upon brass deposition. Studies were identified to undertaken to identify a suitable non-cyanide brass plating bath. The results of experiments on cathodic efficiency, rate of build up and the percentage composition of the alloy deposits from the bath so identified are reported in this paper.
