摘要
采用机械合金化法制备了MgNi非晶,并对不同制备工艺下的MgNi储氢合金的电化学性能进行了测试。对球磨参数、合金微观结构和合金电化学性能之间关系的分析结果表明,球磨过程中的转速、球料比R和球磨时间3个参数对合金电化学的影响是通过对合金微观结构的控制来实现的。
Amorphous MgNi hydrogen storage alloy was synthesized by mechanically alloying (MA). The electrochemistry property of the alloy prepared in different parameters was tested. The relationship between the mechanically alloying parameter. the microstructure of the alloy and the electrochemistry property was analyzed. The results show that the electrochemistry property of the alloy has a strong relationship with milling speed, ball/powder weight ratios(R) and milling time.
