采用熔体旋压技术制备了Ni 7 0 - x / 2 Nb 3 0 - x / 2 Zr x (x = 10、20、30、40和60at%)非晶合金。通过比较这些合金的氢渗透率，得出元素添加的原理。结果发现，Ni-Nb-Zr三元非晶合金的氢渗透率随着Zr含量的增加而增加。然而，Ni 4 0 Zr 6 0 二元非晶合金的氢渗透量远小于Ni 5 0 Nb 1 0 Zr 4 0 非晶合金的氢渗透量。这一行为表明 Nb 的添加也提高了氢渗透性。然后，下一步，我们制备了 Ni-X-Zr（X = Y、Ti、Hf、V、Nb 和 Ta）非晶合金，以研究添加元素对熔纺 Ni-Zr 二元非晶合金氢渗透的影响。结果发现，优选添加具有较高氢亲和力的元素，并且应降低Ni含量以提高磁导率。
The Ni 7 0 - x / 2 Nb 3 0 - x / 2 Zr x (x = 10, 20, 30, 40 and 60 at%) amorphous alloys were prepared by the melt-spinning technique. The hydrogen permeability of those alloys was compared to derive the principles of the element addition. As the result, it was found that the hydrogen permeability of the Ni-Nb-Zr ternary amorphous alloys increases with increasing Zr content. However, the hydrogen permeation of the Ni 4 0 Zr 6 0 binary amorphous alloy was much smaller than that of the Ni 5 0 Nb 1 0 Zr 4 0 amorphous alloy. This behavior indicates that the Nb addition also improves the hydrogen permeability. Then, as a next step, we prepared the Ni-X-Zr (X = Y, Ti, Hf, V, Nb and Ta) amorphous alloys to investigate the effect of the additional elements on the hydrogen permeation of melt-spun Ni-Zr binary amorphous alloys. As the result, it was found that the additional element with higher hydrogen affinity was preferable and that the Ni content should be reduced to improve the permeability.
