Pulse Electrodeposition of Copper-Zinc Coatings from an Alkaline Bath

Abstract

A copper-zinc bath containing EDTA was used for deposition of multi-functional copper-zinc coatings. Copper substrates were used for pulse electrodeposition of copper-zinc coating. Microhardness and wear resistance of copper-zinc coatings has been studied. The films were characterized by scanning electron microscopy and X-ray diffraction. EDS and EDS-dot mapping were also performed to analyse the amount and the distribution of Cu-Zn atoms.
