Molten salt electrolysis was done on V-Ti-Fe alloy prepared by metallothermic reduction,and deoxidation process of the alloy was studied.The influence of electrolysis time on deoxidation degree was investigated.The results show that most of oxygen in V-Ti-Fe alloy can be removed by molten salt electrolysis.With the increase of electrolysis time,oxygen content in the alloy gradually decreases to about 0.2%after 240 min electrolysis.Hydrogen absorption and desorption performances of V-Ti-Fe alloy are improved by electro-deoxidation in molten salt.With the increase of electrolysis time,both the maximum hydrogen absorption capacity and the effective hydrogen desorption capacity increase as high as 2.65% and 1.01%,respectively.
