摘要
本文通过设计硼钛多层复合薄膜结构来提高桥箔的点火能力。利用磁控溅射法交替沉积钛和硼制备多层含能薄膜,单层厚度分别为230 nm和250 nm。对含能薄膜进行X射线衍射图谱测试,结果显示其成分为Ti和B单质状态,并采用HS4540MX12高速运动记录系统记录含能薄膜点火过程,结果表明火花溅射距离可达到30 mm左右。可以推断多层含能薄膜用于制作桥膜可提高火工品的点火能力。
An igniter incorporating B/Ti reactive multilayer energetic films was designed aiming at improving the igniting abilities of explosive bridges. The B/Ti multilayer films were magnetron sputtering deposited on ceramic substrates with individual layer thickness of 230nm and 250nm for titanium and boron. XRD analysis shows that the deposited film consists of titanium and boron. Moreover, the igniting process was recorded using HS4540MX12 high speed camera, sparkles spread to a distance of 3cm were illustrated. It can be deduced that multilayer energetic films will improve the ignition power of initiating explosive device.
