Pd/Nb30Ti35Co35/Pd复合膜在氢气分离和净化方面具有很高的应用潜力。在高温下（4 ~ 400℃），长期氢渗透过程中，钯的层间扩散和钯的聚集是导致通量下降的主要原因。HfN中间层用于限制Pd层与衬底层之间的相互扩散。在500 ~ 600℃的温度下，对Pd/HfN/Nb30Ti35Co35/HfN/Pd复合膜进行了长期的氢渗透试验。HfN层提高了复合膜在500 ~ 550℃温度范围内的渗透稳定性。HfN层的增强效果与HfN层的厚度和操作温度有关。提出了一个预测模型，揭示了HfN层影响下的通量-时间依赖关系。
Composite membranes of Pd/Nb30Ti35Co35/Pd exhibit high potential in hydrogen separation and purification applications. There are two factors, interlayer diffusion and aggregation of Pd, causing the flux degradation during long-term hydrogen permeation at high temperatures (>400 °C). HfN intermediate layer is used to restrict the interdiffusion between the Pd layer and the substrate layer. The long-term hydrogen permeation tests of Pd/HfN/Nb30Ti35Co35/HfN/Pd composite membranes were conducted at temperatures from 500 to 600 °C. The HfN layer improved the permeation stability of the composite membranes in the temperature range of 500–550 °C. The enhanced effect of the HfN layer is related to the thickness of HfN and the operating temperature. A prediction model was proposed to reveal the flux-time dependence relationship with the influence of the HfN layer.
