摘要
以机械粉化的La Ni4.25Al0.75贮氢合金粉末为基底材料,对其表面进行Pd–P化学镀覆。通过扫描电镜、能谱仪、X射线衍射仪等对沉积膜层的表面形貌和成分结构进行表征和分析。考察了化学镀覆Pd–P前后La Ni4.25Al0.75合金粉末的贮氢性能。结果表明,在La Ni4.25Al0.75颗粒表面化学镀覆Pd–P膜层能够改善其抵抗O2和N2毒化作用的能力。
Electroless Pd-P plating was conducted using mechanically pulverized LaNi4.25Al0.75 hydrogen storage alloy powder as substrate. The surface morphology and structure of the deposited film were characterized by scanning electronic microscope, energy-dispersive spectroscope, and X-ray diffractometer. The hydrogen storage properties of LaNi4,25Al0.75 alloy powder before and after electroless Pd-P plating were studied. It is shown that the Pd-P film electrolessly plated on the surface of LaNi4.25Al0.75 particle is beneficial to improving its resistance against the toxic effect of O2 and N2 impurities.
