    摘要:

    本文利用磁控濺射成功制備了Ti/ZrCo/Ti、ZrCo/Ti/ZrCo/Ti多層復(fù)合薄膜,研究了復(fù)合薄膜的微觀結(jié)構(gòu)與貯氫性能,深入探討了所制備復(fù)合膜作為氘氚中子發(fā)生器氚靶部件的應(yīng)用可能性。結(jié)果表明,所制備的多層復(fù)合薄膜是由ZrCo相和Ti相組成,各膜層間的界面清晰可辨。相比ZrCo 等單層薄膜,夾層Ti的引入不僅顯著提升了復(fù)合薄膜的吸氫量,還使薄膜氫化物的具有較高的穩(wěn)定性。更可喜的是所制備ZrCo/Ti儲(chǔ)氚復(fù)合膜未發(fā)生明顯歧化反應(yīng)。本工作所構(gòu)建的ZrCo、Ti相互交替的多層復(fù)合膜結(jié)構(gòu),拓展了ZrCo合金的應(yīng)用領(lǐng)域,可為高容量、高熱穩(wěn)定性新型復(fù)合膜氚靶材料的設(shè)計(jì)開(kāi)發(fā)提供了重要參考。

    Abstract:

    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.
