Electrochemical synthesis of intermetallic compounds of cobalt and neodymium in chloride melts

The electrodeposition of neodymium on a cobalt substrate in a chloride-fluoride melt NaCl-KCl — 10 wt. % NaF — 5 wt. % NdF3was studied. It is shown that during electrolysis, a coating with a crystal size of 2–5 microns is formed. Microanalysis of the coating determined the electrocrystallization of the intermetallic compounds Co17Nd2 and Co5Nd on a cobaltsubstrate.
