Electrodeposition of Со-W alloy coverings from citrate electrolytes with brilliance-forming and smoothing additives was investigated. It is shown, that introduction of these additives in electrolytes of said type promote improvement of surface quality, approaching roughness of coating to roughness of the polished substrate. Application of such additives cause covering amorphization and improve physicomechanical cha- racteristics of received platings.
