Received March 19, 2007 Abstract — Electrochemical behavior of cobalt in a tungstate melt, as well as the effect of electrolysis conditions on the composition and structure of cobalt–molybdenum (tungsten) alloy deposits from tungstate–molybdate melts is studied. With a decrease in the concentration of cobalt and an increase in the concentration of molybdenum (tungsten) in the melt, the phase composition of cathodic deposits is shown to change from individual cobalt to individual molybdenum (tungsten) via a series of cobalt–molybdenum (tungsten) alloys of var-ious compositions.
