| 摘 要： | 为了提高Ni-Cr薄膜发火件的安全性和点火能力,使用磁控溅射技术将Al/CuO含能薄膜与Ni-Cr薄膜发火件复合,制备了一种新型的Ni-Cr@Al/CuO钝感含能元件。该Ni-Cr@Al/CuO钝感含能元件既可以用作换能元,又可以作为最简单的电点火元件,从而简化点传火序列,适应弹药微型化的发展需求。测试其1A1W5min安全性、电发火感度和点火能力。结果表明,Ni-Cr@Al/CuO钝感含能元件满足1A1W5min安全性要求;50 ms临界发火电流为3.08 A,最小全发火电流为3.18 A,最大不发火电流为2.98 A,安全裕度较高;在相同条件下,Ni-Cr@Al/CuO钝感含能元件可以点燃硼/硝酸钾,并且可实现1 mm的间隙点火,而Ni-Cr薄膜发火件不能成功点燃硼/硝酸钾。

| Abstract: | In order to improve the safety and ignition ability of Ni-Cr thin film igniter, a new Ni-Cr@Al/CuO insensitive energetic element was fabricated by combining Al/CuO energetic thin film with Ni-Cr thin film bridge by magnetron sputtering. The Ni-Cr@Al/CuO insensitive energetic element can be used both as the energy transducer element and as the simplest electrical ignition elements. It simplified the point fire transmission sequence and adapt to the development needs of ammunition miniaturization. The safety of Ni-Cr@Al/CuO was tested at the loading condition of 1A1W5min, and its electric ignition sensitivity and ignition capability were tested. The results show that the 50 ms critical ignition current of the insensitive nucleus Ni-Cr igniter is 3.08 A, 99.9% firing current is 3.18 A, 0.1% firing current is 2.98 A. Under the same conditions, Ni-Cr@Al/CuO insensitive energetic element can ignite B/KNO3, besides, it can achieve 1mm gap ignition, while Ni-Cr thin film igniter can not successfully ignite B/KNO3. |
