中文摘要：

有 Mg20Ni10-xCox 的名字的作文的 Mg2Ni 类型合金(x=0， 1， 2， 3， 4， % ，集体部分) 被融化旋转技术准备。合金的结构被 XRD， SEM 和 HRTEM 学习。氢吸收 / 解吸附作用动力学和合金的电气化学的表演被测量。没有非结晶的阶段形成在的结果表演同样旋转共同释放合金，而是包含公司表演的同样旋转的合金非结晶的阶段的某个数量。当演员组合金的氢吸收能力首先与公司内容的增长变化增加然后减少。当演员组和旋转合金的氢解吸附作用能力与增加公司内容升起。显著地旋转的 melt 改进加氢和除氢作用能力和合金的动力学。为 Ni 的公司的替换清楚地提高合金和同样旋转的合金的周期稳定性的分泌物能力。

英文摘要：

The Mg2Ni-type alloys with nominal compositions of Mg20Ni10-xCox（x=0,1,2,3,4,%,mass fraction） were prepared by melt-spinning technology.The structures of the alloys were studied by XRD,SEM and HRTEM.The hydrogen absorption/desorption kinetics and the electrochemical performances of the alloys were measured.The results show that no amorphous phase forms in the as-spun Co-free alloy,but the as-spun alloys containing Co show a certain amount of amorphous phase.The hydrogen absorption capacities of the as-cast alloys first increase and then decrease with the incremental change of Co content.The hydrogen desorption capacities of as-cast and spun alloys rise with increasing Co content.The melt spinning significantly improves the hydrogenation and dehydrogenation capacities and kinetics of the alloys.The substitution of Co for Ni clearly enhances the discharge capacities of the alloys and the cycle stability of the as-spun alloys.
