摘要
介绍了放电等离子烧结制备储氢合金的可行性,从La-Mg-Ni系、Mg基、Ti-V基合金的微观结构及其吸放氢性能等角度综述了放电等离子烧结在储氢合金中的应用研究进展,并指出储氢合金吸放氢性能的改善原因在于适当温度的放电等离子烧结促进了合金中新相的形成,控制了合金晶粒尺寸。
The feasibility of hydrogen storage alloy prepared by spark plasma sintering （SPS） was introduced.Research progress in the application of SPS on preparation of hydrogen storage alloy was summarized according to the microstructure and hydrogen absorption/desorption properties of La-Mg-Ni system,Mg-based and Ti-V based alloy.It was pointed out that the improvement of hydrogen absorption/desorption properties of the alloy was attributed to the fact that SPS at appropriate temperature could promote the formation of new phase in hydrogen storage alloy and control the grain size of the alloy.
