Resumo:Title screen
The influence of dispersivity of micron-sized industrial Al powders with interval of the particles diameter of 0.18-11.0 [mu]m on their resistance to oxidation in the saturated water vapor atmosphere at its different partial pressures has been studied. It was experimentally shown the effect of increasing the stability of powders with a higher proportion of submicron particles to oxidation when exposed to water vapor, which consists in reducing the degree of oxidation with increasing dispersivity of Al powders under the same exposure conditions to water vapor. Enhancing the stability of submicron and nanoparticles of Alto oxidation with water vapor was explained by the formation on the particle surface a special charge state of the oxide film (double electric layer) which slows the diffusion of oxidant to the metal core of particles.
