Electrochemical hydrogenation of Ti-Ni powder after mechanical activation

Abstract

The paper studies electrochemical hydrogenation of Ti-Ni powder after mechanical activation. High-energy mechanical activation was performed using a planetary ball mill with rotation speed of 1820 rpm for 10 s. The initial powder after mechanical activation has a mixture of phases TiNi (B2) and (B19c), Ti₂Ni, and TiNi₃ with the lattice parameters corresponding to those reported in literature. When hydrogenation time increases, the lattice parameter of the Ti₂Ni phase only significantly changes, and 90 min of hydrogenation is the incubation period of this process, when the lattice parameter of the Ti₂Ni phase changes within the error. Electrochemical hydrogenation performed for more than 90 minutes causes formation of the Ti₂NiH_x phase based on Ti₂Ni, and 140 and 180 min of hydrogenation is sufficient to form the Ti₂NiH_0.5 stoichiometry.
