The present paper has represented the results of the research of electrochemical deposition of coatings based on Co-W alloy from the citrate electrolyte. Possibility to obtain large (more than 40 μm) thicknesses without cracking has been demonstrated. Peculiarities of the surface relief structure change after increase of the coating thickness have been researched. Possibility to control a concentration of tungsten in the coating alloy within the range 14 at.% – 21 at.% has been shown. Dependence of the coating microhardness on the thickness has been represented.
