摘　　要：利用磁控溅射法制备了不同调制周期的多层Al/Ti纳米含能桥膜,并在电容放电激励下对其电爆性能进行测试,Al/Ti纳米含能桥膜的爆发时间随着电压的增大而降低,而等离子体持续时间随着电压的增加而增大。高速摄影仪记录的Al/Ti纳米含能桥膜的电爆过程表明,在相同的激励电压下,Al/Ti纳米含能桥膜的电爆现象明显比Al桥膜和Ti桥膜剧烈,且伴随着高温粒子四处飞溅,飞溅高度约有4~6 mm,同时Al/Ti纳米含能桥膜的电爆持续时间均长于Al桥膜和Ti桥膜的电爆持续时间,这与伏安特性曲线得出的结论一致。Multi-layered Al/Ti nano-energetic bridge films were prepared by RF magnetron sputtering with different modulation period. Electric explosion performances were investigated when Al / Ti nano-energetic bridge films were ignited using a capacitor-discharger power supply. The outbreak time of Al / Ti nano-energetic bridge film increased with voltage decrease and plasma duration time increased with the increase of voltage. The electric explosion processes of Al bridge film,Ti bridge film and Al / Ti nano-energetic bridge films were recorded by high-speed photography respectively. The results show that Al / Ti nano-energetic bridge films have more drastic electric explosion,the high temperature splash particles of Al / Ti nano-energetic bridge films are about 4-6 mm high. And the duration of electric explosion time of Al / Ti nano-energetic bridge films is higher than Al and Ti bridge films,which are consistent with the volt-ampere characteristic curves.
