本文研究了氢化物ＴｉＨ２对Ｆｅ＋Ｔｉ机械合金化非晶储氢合金的表面成份偏聚和性能的影响。应用Ｘ射线光电子谱（ＸＰＳ）和俄歇电子谱（ＡＥＳ）对样品表面由表及里逐层测量成份分布。同时应用热重分析方法研究了样品氧化性能和产物。研究结果表明，在机械合金化过程中，Ｈ原子不仅能使ＦｅＴｉ非晶化，同时促使表面产生明显的Ｆｅ原子偏聚。表面Ｆｅ／Ｔｉ原子比接近７。非晶ＦｅＴｉ（Ｈ）相的氧化分两个阶段进行，Ｔｉ原子首先氧化（８３３Ｋ），随后Ｆｅ原子氧化（８９０Ｋ）。
The effect of TiH2 hydride on the segregation and properties of the surface of Fe + Ti mechanically alloyed amorphous hydrogen storage alloy was studied in this paper. The composition distribution of the sample surface was measured layer by layer using X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). At the same time, the thermogravimetric method was used to study the oxidation performance and the product of the sample. The results show that in the process of mechanical alloying, H atoms not only make FeTi amorphous, but also promote the surface to produce obvious Fe atom segregation. Surface Fe / Ti atomic ratio close to 7. Oxidation of the amorphous FeTi (H) phase takes place in two stages, the Ti atom being oxidized first (833K) followed by the Fe atom oxidation (890K).
