摘　　要：根据机械合金化和界面固相扩散反应的基本原理,合成出了一系列不同原子配比的Mg-Ni系储氢合金箔(Mg,Ni原子配比分别是8∶1,4∶1,2∶1及1∶1)。研究了Mg-Ni系储氢合金箔的组成及其储氢性能。结果表明,Mg8Ni合金箔的吸放氢温度最低可降至300℃,Mg4Ni和Mg2Ni合金箔在250℃就可部分氢化,且放氢量均可达到2.5%(质量分数)以上;MgNi合金箔吸氢量较低,但放氢温度有所降低。Based on the theory of mechanical alloying and boundary surface solid diffusion, the high performance Mg-Ni based hydrogen storage alloy foil was synthesized,and its composition and hydrogen storage properties were studied.The hydrogen storage property of Mg-Ni based alloy film with different deposition nickel is indicated that the property of Mg film is greatly improved.The hydrogen absorption and desorption temperatures of Mg8Ni film are decreased down to 300 ℃,and Mg4Ni and Mg2Ni films can be hydriding in 250 ℃,and their dehydriding capacity is not less than 2.5%,the capacity of MgNi film is low,but its dehydriding temperature decreases some degrees.
