Properties of Ni-Co Alloy Coating Prepared from Sulphate Bath

Abstract:

The paper deals with nickel – cobalt coatings on the copper substrate prepared by electroplating process. The different Co content in the alloy coating depending on chemical composition of sulphate electrolyte and current density. The microstructure and composition of Ni-Co coating were observed with use of light and scanning electron microscopy. The mechanical properties were determined with use of the test according to EN ISO 6892-1:2009 standard and means of a Vickers microhardness tester. The results showed that under the same bath composition and technological parameters of process the Ni-Co alloy coating exhibited laminated structure. Their strength and hardness of the deposited coatings were higher than those for the Ni coatings.
