Electrodeposition of Nb-Sn alloy from SnCl2-NbCl5-EMIC ambient temperaturemolten salts

The electrodeposition of the Nb-Sn alloy from the SnCl2-NbCl5-EMIC melt was investigated. From the results of the physical properties and cyclic volta mmetry, the possibility of electrodeposition of the Nb-Sn alloy was suggest ed, which was subsequently obtained from the melt by electrodeposition. How ever, the Nb content in the deposits was very low. The low Nb content was r elated to the low limiting current density of Nb. From the results of bath temperature, melt composition and pulse electrolysis for increasing the Nb content in the deposits, the Nb-Sn alloy containing 69.1 wt % Nb was obtain ed from the 2.8 mol % SnCl2-68.6 mol % NbCl5-28.6 mol % EMIC melt at 200 mA cm(-2) with a pulse period of 10 ms, duty ratio of 0.2 at 160 degrees C.
