A review on effect of Metallic Coatings on the Ignition Characteristics of Aluminum

The exothermic of aluminum oxidation and its relatively low price, make Al combustion desirable for utilization in solid propellant formulations. This usage aids to improve rocket performance characteristics in particular it increases the specific impulse. However, efficient ignition and burning of aluminum is a problem due to the strong oxide layer naturally formed on aluminum. To improve burn efficiency and to increment of burning rate, one route is creation of metal coatings (Fe and Ni) on Al particles. In this paper investigate influence of this approach on the ignition characteristics of aluminum.
