Abstract
This paper presents the results of an experimental study of the effect of particle encapsulation on the main operating parameters and features of the ignition and combustion of aluminum particles in air. It is found that the application of a nickel-based coating to the aluminum-particle surface, which substitutes for the oxide film, increases the reactivity of the aluminum-air mixture, with retention of the initial particle dispersity and energy parameters of the mixture. The model developed for the encapsulated-particle ignition taking into account the stress-strained state of the particle was used to determine the time and temperature limits for the retention of the protective-coating properties and to explain the experimental results.
