用溅射法将工业硅涂膜到TiFe合金上,在外表面形成一层非晶态Si膜,经贮氢性能测试活化性能较原合金有明显的改善,XRD和XPS分析表明在TiFe合金上存在非晶态Si,在TiFe外表面有大量Si元素,由SEM图看出,涂膜Si和未涂膜Si的合金,贮氢前后在形貌上均存着明显差别,初步认为是一种可开发的贮氢材料。
An evident improvement on activation properties of hydrogen storage was made by sputtering an amorphous coating of commercial Si on TiFe alloy. SEM observation revealed an obvious difference betwwen the morphologies before and after hydrogen storage for TiFe al-loy with or without amorphous Si coating. It is believed that this may be quite a developable hydrogen storage material.
