摘要
本工作采用超高真空气相氢渗透技术,在140—400℃温度范围内,测定了氢在纯 Ni(不同冷变形量)中的渗透率、扩散系数和溶解度常数,研究了冷加工对氢渗透和扩散行为的影响。结果指出,在实验温度范围内,氢在纯 Ni 中的渗透率和扩散系数均遵循 Arrhenius 方程,纯 Ni 的冷加工对氢渗透和扩散行为没有明显影响。
Permeability,diffusivity and solubility of hydrogen in different cold deformednickel have been measured by gaseous permeation technique over the temperature range of 140to 400℃.The effects of cold working on hydrogen permeation and diffusion have been investi-gated.The results indicated that permeability and diffusivity of hydrogen in pure nickel over theexperimental temperature range follow Arrhenius equations and hydrogen permeation and dif-fusion behaviour are not obviously influenced by cold-work of pure nickel.
