Abstract

Abstract: Micro/nano-aluminum powders have extensive application prospect in the field of explosives and propellants. In order to reveal the combustion mechanism of micro/nano-aluminum powders in propellants, the ignition and combustion properties of different types of micro/nano aluminum powders are studied by CO₂ laser ignition device. The results show that ignition and combustion properties of micro/nano-aluminum powders are better than those of the nano-aluminum powders. Ignition delay time of 80nm aluminum powder is longer than that of 120 nm aluminum powder, which is caused by the decrease in the internal and external pressures because of the reduction in active aluminum content. Ignition and combustion mechanisms of micro/nano aluminum powders are analyzed. The ignition and combustion properties of micro-aluminum powders after surface modification by nickel nanopowders are improved, and the nickel nanoparticles are treated as the carrier of oxygen. Ignition delay time of aluminum nanoparticles coated with organic matter is increased. However, they could prevent the aluminum nanopowders from oxidating and enhance the energy performance. The energetic polymer is still seen to be well done in the surface coating of aluminum nanopowders.

Key words: ordnance science and technology, micro/nano-aluminum powder, energetic polymer, nickel nanopowder, composite particle, laser ignition, ignition delay time
