Combustion of activated aluminum

摘要: Abstract Combustion of activated aluminum was studied by four different methods: microscopic imaging the preignition process, digital combustion process at pressures up to 64 bar in air, nitrogen, and carbon dioxide, TGA, DSC. Activation three fundamentally methods found effective enhancing both ignitability burn rate. The complex fluoride coating prevented agglomeration completely all stages combustion, while nickel cobalt coatings promoted oxide but metal before combustion. Nickel catalyzed nitride formation, accelerating rate more than other air most dioxide. Carbon coagulation dioxide quenched burning many cases higher 8 bar. activation accelerated CO 2 extremely effectively, did not prevent shell formation subsequent quenching high pressures. Ni negated effects , enhanced only slightly. Co reduced accelerate . Only applied large amounts nitrogen.
