中文摘要：
基于 Mg 的氢存储合金 MgNi， Mg0.9Ti0.1Ni，和 Mg0.9Ti0.06Zr0.04Ni 成功地借助于机械 alloying (麻省) 被准备。结构和这些基于 Mg 的材料的电气化学的特征被学习。X 光检查衍射(XRD ) 结果证明合金的主要阶段展出非结晶的结构。扫描电子显微镜学(SEM ) 相片证明 Ti 和 Zr 的粒子尺寸代替了合金是在直径的大约 24 m。合金的周期生活被增加 Ti 和 Zr 延长。在 50 个费用分泌物周期以后， Mg0.9Ti0.06Zr0.04Ni 的分泌物能力比 MgNi 合金的高是 91.74% 并且 37.96% 比 Mg0.9Ti0.1Ni 的高合金。为电极能力腐烂的主要原因是 Mg 的形成(哦) 2 (Mg 腐蚀的产品) 在合金的表面。potentiodynamic 极化结果显示做的 Ti 和 Zr 在一个碱的答案改进耐蚀。电气化学的阻抗光谱学(EIS ) 结果建议做的 Ti 和 Zr 的那合适的数量显著地改进电气化学的催化活动。
英文摘要：
Mg-based hydrogen storage alloys MgNi, Mg0.9Ti0.1Ni, and Mg0.9Ti0.06Zr0.04Ni were successfully prepared by means of mechanical alloying （MA）. The structure and the electrochemical characteristics of these Mg-based materials were studied. The X-ray diffraction （XRD） result shows that the main phases of the alloys exhibit amorphous structure. The scanning electron microscopy （SEM） photograph shows that the particle size of Ti and Zr substituted alloys was about 2-4 μm in diameter. The cycle lives of the alloys were prolonged by adding Ti and Zr. After 50 charge-discharge cycles, the discharge capacity of Mg0.9Ti0.06Zr0.04Ni was 91.74% higher than that of MgNi alloy and 37.96% higher than that of Mg0.9Ti0.1Ni alloy. The main reason for the electrode capacity decay is the formation of Mg（OH）2 （product of Mg corrosion） at the surface of alloy. The potentiodynamic polarization result indicates that Ti and Zr doping improves the anticorrosion in an alkaline solution. The electrochemical impedance spectroscopy （EIS） results suggest that proper amount of Ti and Zr doping improves the electrochemical catalytic activity significantly.
