Effect of Vanadium on Activated Hydrogenation of Mechanically Treated Zirconium-Containing Alloys

Abstract

The mechanical treatment of powders with nickel additives as a hydrogen chemisorption activator (catalyst) is used to activate the hydrogenation of zirconium-containing alloys. Polarization curves are used to study the kinetics of electrochemical release and sorption of hydrogen on zirconium alloys with different additives when aluminum is replaced by vanadium. It is shown that this replacement is efficient and the maximum hydrogen capacity depends on the optimum concentrations of catalyst additives into the alloy.
