The experimental results of the macroscopic spherical particles penetration in the half-infinite aluminium and steel targets have been analyzed. It is shown, that for particles, having sizes about 50–100 $\mu m$ and velocities in the range 1000–3000 {m}/{s}, the hydrodynamical penetration model is not applicable. Under such conditions the penetration procedure is determined by the processes, taking place immediately in front of the particles surface. It fundamentally differs from models, suiting for describing the damage of target metal under the influence of large mechanical bodies. The specific penetration model for macroscopic particles, having small size have been formulated. The special properties of this mechanism which distinguish it from the common approach are shown.
Keywords: penetration procedure, blast surface alloyage, hydrodynamical penetration model, radial expansion.
