    Abstract:

    Carbamide melts have found applications as electrolytes for electrochemical treatment of metals [1, 2]. The possibility of electrodeposition of cobalt from carbamide melts at 408 K has been examined for tungsten as an example. When studying the electrochemical behaviour of cobalt oxide in molten carbamide, it can be concluded that maximum limiting currents are typical of the system (NH2)2CO-CoO. Cobalt coatings on nickel cathodes have been obtained by the electrolysis of the molten system (NH2)2CO-CoO at current densities of 20-30 mA/cm2.
