Abstract

This paper presents a physico-mathematical model of the high-temperature oxidation of a nanosized aluminum particle coated with a nickel layer. The model is built under the hypothesis that, initially, the reaction of self-propagating high-temperature synthesis occurs with the formation of NiAl, and then the remaining unreacted aluminum is oxidized. The model takes into account the diffusion of the oxidizing agent and aluminum vapor through the formed spherical layer of NiAl and aluminum oxide around the aluminum melt, and the temperature dependence of the reaction between oxygen and aluminum. The conducted parametric study has been shown that at ambient gas temperatures in the range of 1200 K÷1600 K, a nanosized aluminum particle coated with nickel burns faster than uncoated one, while as at higher temperatures, a nickel-coated aluminum particle burns more slowly than uncoated.
