Electrodeposition of Nb-Sn alloy from ambient temperature molten salt electrolytes, i.e., an SnCl2-NbCl5-BPC (1-butylpyridinium chloride) system and an Sn-NbCl5-BPC system, by pulse electrolysis was investigated. The Nb content in the Nb-Sn electrodeposit was effected by the pulse period, current density, and duty ratio. Decreasing the duty ratio and increasing the current density increased the Nb content in the Nb-Sn alloy deposited from a 28.6mol%SnCl2-14.3mol%NbCl5-57.1mol%BPC bath. An Nb-Sn alloy containing 44.3wt% Nb was obtained from this bath at 60mA·cm-2, T=50ms, and a duty ratio of 0.2, An Nb-Sn alloy containing 41.3wt% Nb was deposited from a 7.7mol%Sn-15.4mol%NbCl5-76.9mol%BPC bath at 60mA·cm-2, T=10ms, and a duty ratio of 0.2.
