镁基合金具有重量轻、吸氢能力强等优点，因此在近几十年来得到了广泛的研究。石墨作为氢吸收剂近来也受到极大关注。本文采用球磨法制备了Mg-C合金，并对其加氢性能进行了研究。首先将粉末与1：1摩尔比的Mg与石墨混合。研磨球和罐由SUS 304制成。该工序在Ar气体气氛下，用振动球磨机以11.8Hz的速度进行60小时。将制备的粉末在填充有Ar气体的手套箱中处理。球磨后，样品显示出新的X射线衍射峰，其不是来自Mg和/或石墨的峰。在453 K和1.8 MPa氢气压力下证实了粉末与氢气的亲和力。从热脱附光谱（TDS）谱估计吸收的氢的总量为2.0重量%。
Magnesium based alloys possess light-weight and high hydrogen absorption capacity so that they have been investigated extensively for several decades. Great attention also has recently been paid to graphite as a hydrogen absorber. In this study Mg-C alloys were prepared by ball milling and their hydrogenation properties were investigated. Powders were first mixed with a 1 : 1 molar ratio of Mg to graphite. Milling balls and a pot were made of SUS304. This process was performed with a vibration ball mill at the speed of 11.8 Hz under an Ar gas atmosphere for 60 hours. The prepared powders were handled in a glove box filled with an Ar gas. After ball milling, samples showed a new X-ray diffraction peak, which was either not a peak from Mg and/or graphite. An affinity for the powders with hydrogen was confirmed at 453 K and the 1.8 MPa hydrogen pressure. The total amount of absorbed hydrogen was estimated to be 2.0 wt% from the thermal desorption spectroscopy (TDS) spectrum.
