Abstract
It is shown experimentally by explosive compacting of aluminum-based alloy granules and powder mxtures that the particle surface state, i.e., the thickness of the oxide (hydroxide) and of the adsorbed coatings has a significant effect on the magnitude of pressure, at which binding of the particles behind a shock wave front occurs. Both the initial granules and powders and those chemically cleaned were subjected to loading. Formulas are derived for calculating the binding shock wave pressure.
