在容积为20 m3的烟幕箱中,测试了30 g纳米TiN形成的烟幕对1.06μm激光、10.6μm激光、3～5 μm红外及8～12 μm红外的干扰性能,结果表明,纳米TiN烟幕对各波段红外辐射的遮蔽/干扰效果良好,质量消光系数均基本大于1 m2·g-1,与常规材料的烟幕性能比较表明,纳米TiN烟幕消光性能好,是一种能有效干扰1.06.μm,10.6μm激光测试系统及3～5 μm,8～12μm红外热像仪的新型烟幕材料.%In 20 m3 smoke chamber, the jamming effects of 30 g nanometer crystalline titanium nitride( nano-TiN) smoke are tested. Tests are done not only to 1.06 μm and 10.6 μm laser but also to 3 - 5 μm and 8 ~ 12 μm IR. The experimental results show that nano-TiN smoke exhibits excellent extinction ability to broadband IR radiation and the mass extinction coefficients are all above 1 m2 ? G -1. Compared with the smoke performance of conventional materials (such as HC,RP,oil,graphite,carbon black) ,nano-TiN smoke possesses better obscuration capability. Therefore,it is a new obscurant material which can effectively jam the broadband IR devices including 1.06 μm.10.6 μm,3 -5 μm and 8-12 μm.
