ZrCo/Ti储氚复合膜的制备及性能研究

本文利用磁控溅射成功制备了Ti/ZrCo/Ti、ZrCo/Ti/ZrCo/Ti多层复合薄膜,研究了复合薄膜的微观结构与贮氢性能,深入探讨了所制备复合膜作为氘氚中子发生器氚靶部件的应用可能性。结果表明,所制备的多层复合薄膜是由ZrCo相和Ti相组成,各膜层间的界面清晰可辨。相比ZrCo 等单层薄膜,夹层Ti的引入不仅显著提升了复合薄膜的吸氢量,还使薄膜氢化物的具有较高的稳定性。更可喜的是所制备ZrCo/Ti储氚复合膜未发生明显歧化反应。本工作所构建的ZrCo、Ti相互交替的多层复合膜结构,拓展了ZrCo合金的应用领域,可为高容量、高热稳定性新型复合膜氚靶材料的设计开发提供了重要参考。

Study on Preparation and Performance of ZrCo/Ti Tritium Storage Composite Film

Ti/ZrCo/Ti, ZrCo/Ti/ZrCo/Ti multilayer composite films are successfully prepared by magnetron sputtering.The micro-structure and hydrogen storage performance of multilayer composite films are studied,The application possibility of the composite membrane as the tritium target of the deuterium tritium neutron generator is discussed in detail.Experiments show that the prepared multilayer composite film is composed of ZrCo phase and Ti phase, and the interface between the layers is clearly distinguishable. Compared with the ZrCo film, the introduction of the Ti film layer significantly increases the hydrogen absorption of the composite film and retains the stability of the film hydride. At the same time, the disproportionation reaction of ZrCo is significantly suppressed.The alternating composite film of ZrCo layer and Ti layer constructed in this study has high hydrogen absorption capacity and high thermal stability, which extends the application field of ZrCo alloy and provides an important reference for the design and development of new tritium target materials of composite film.
