Application of volumetric electric-spark dispersion for the fabrication of Ti–Zr–Ni hydrogen storage alloys

Results of X-ray and electrochemical analyses of properties of Ti–Zr–Ni powders obtained by the volumetric electric-spark dispersion method in water, alcohol, kerosene, liquid nitrogen and liquid argon are presented. The influence of working fluids and parameters of discharge pulses on the chemical composition, phase-structural state, electrochemical characteristics and electrical capacity of the obtained powders is considered. The effect of annealing in various media on the electrochemical properties of powders has been studied.
