Specific features of microparticle deformation upon impact on a rigid barrier

Based on experimental data and numerical modeling, it is shown that a lamina of melted metal of thickness of order 0.01 $d$, in which the temperature is close to the melting point of the particle material, can be formed upon high-speed impact ($v_0\approx$500-1200 m/sec) of a fine metal particle ($d$ = 1–50 $\mu$m) on a rigid undeformable barrier near the contact surface.
