Влияние оксида алюминия на пороги лазерного зажигания смеси нанопорошка алюминия и оксида железа

Влияние оксида алюминия на пороги лазерного зажигания смеси нанопорошка алюминия и оксида железа

Abstract

The paper introduces the results of experimental researches on pyrotechnic composition (aluminum nanopowder + iron oxide) ignition by laser radiation (?=1,06 µm) with pulse duration 3,5 ms. The authors have measured energy thresholds of laser ignition of the investigated composition and the composition with aluminum oxide admixtures at different press in densities. Phase composition of end combustion products was studied. It was ascertained that the admixtures of aluminum oxide nanopowder into iron-aluminum termite reduce energy ignition thresholds when increasing sample density.

Приведены результаты экспериментальных исследований по зажиганию пиротехнического состава (нанопорошок алюминия + оксид железа) лазерным излучением (?=1,06 мкм) с длительностью импульса 3,5 мс. Измерены энергетические пороги лазерного зажигания исследуемого состава и состава с добавками оксида алюминия при различных плотностях запрессовки. Исследован фазовый состав конечных продуктов сгорания. Установлено, что добавки нанопорошка оксида алюминия в железо-алюминиевый термит с увеличением плотности образцов снижают энергетические пороги зажигания.
