Abstract

The electrochemical behavior of nickel and cobalt in a tungstate melt and the effect of the electrolysis conditions on the composition and structure of the deposits of the nickel (cobalt)–molybdenum (tungsten) alloys and intermetallic compounds in oxide tungstate melts are studied. As the molybdenum (tungsten) concentration in the melt increases or the nickel (cobalt) concentration decreases, the phase composition of the cathodic deposits changes from nickel through nickel (cobalt)–molybdenum (tungsten) alloys and intermetallics of different compositions to pure molybdenum (tungsten).
