Reactive multilayer films (RMFs) are a type of a thermite nanoenergetic multilayer film, which can be potentially applied to an exploding foil flyer generator (EFFG). Herein, Al/Ni RMFs with a bilayer thickness of 500 nm are integrated into an exploding foil layer by a magnetron sputtering method. The effects of interface layer on the properties of the EFFG are systematically investigated in terms of the electrical behavior and flyer velocity. The interface layer is controlled by annealing, whose structure and chemical composition are confirmed by X‐ray diffraction and transmission electron microscopy. The periodic multilayer structure can be clearly visible, and the thickness of interface layer increases with increasing annealing temperatures from room temperature to 573 K. The EFFG integrating as‐deposited Al/Ni RMFs exhibits improved exploding properties with a short exploding time, violent explosion region, and high flyer velocity phenomenon in comparison with generator at 573 K. Overall, the EFFGs integrated Al/Ni RMFs with larger interface layers can decrease the electrical plasma performances, which are significant for investigating the applicability in various engineering fields.

界面层对铝/镍多层集成炸箔飞片发生器性能的影响

反应性多层膜（RMFs）是一种铝热剂纳米高能多层膜，可潜在地应用于爆炸箔飞行器发生器（EFFG）。在此，通过磁控溅射法将双层厚度为500nm的Al / Ni RMF整合到爆炸箔层中。界面层对EFFG性能的影响是根据电学行为和飞片速度进行系统研究的。界面层通过退火控制，其结构和化学成分通过X射线衍射和透射电子显微镜确定。周期性多层结构可以清晰可见，并且界面层的厚度随着退火温度从室温升高到573 K而增加。
