摘要
在研究含Ｓｍ＜８ａｔ％的Ｐｄ─Ｓｍ合金透氢特性中发现高Ｓｍ量使透氢量急剧增大。测量合金的溶氢特性、扩散系数之后，提出这种合金的反常透氢特性是由表面活性改变引起的。这可能与合金内部组织有序化程度直接相关。
The anomaly hydrogen permeability of Pd-8 at.%Sm alloy was detected,It was discovered that high amount of Sm made the amounts of hydrogen permeated increase rapidly,The measurements of hydrogen solbility and hydrogen diffusion in Pd-Sm alloy resulted in that the anomaly hydrogen permeability of the alloy was caused by the change of surface activity and was possible to directly correlate with the level of long-range order in Pd-Sm alloy.
