Electrodeposition of multicomponent Co–Cr–Fe–Mn–Ni alloy

This work is focused on the initial realization of a multi-component coating deposition from the aqueous solution. The Coating composed of the elements Co-Cr-Fe-Mn-Ni was prepared by electroplating process. The chosen substrate was copper. The purpose of the work was to apply the high entropy alloy, which is defined as alloy with structure of a solid solution containing five or more elements in an approximately equal atomic ratio. The use of electrodeposition in this area is rare. The conditions of the plating process, the percentage of the metal ions and cohesion of the layers were studied. The morphology of the excluded coatings was monitored by scanning electron microscopy and their elemental composition was verified by the EDS analysis. The wear resistant features were examined approximately before and consequently also after the thermal resistance testing.
