TiFe 贮氢合金活化困难。通过在表面上焊接 LaNi_5微粒,TiFe 合金的活化性能得到改善,可以在室温3MPa 氢压下一次完全活化。SEM 和电子探针分析表明,焊有 LaNi_5微粒的 TiFe颗粒具有麻球状结构。焊接于表面的 LaNi_5微粒起着吸氢窗口的作用,促进了 TiFe 的活化。
TiFe hydrogen storage alloy activation difficult. By welding LaNi_5 particles on the surface, the activation performance of the TiFe alloy is improved, and the TiFe alloy can be completely activated at a hydrogen pressure of 3 MPa at room temperature. SEM and electron probe analysis showed that TiFe particles welded with LaNi_5 particles have a spherulitic structure. The LaNi_5 particles soldered on the surface function as a hydrogen absorbing window and promote the activation of TiFe.
