Investigation of Impact Resistance of Protective Barriers Made from Cermets

Resumo

Ceramic-metal materials (cermets) based on titanium diboride and boron carbide are designed and produced by the method of self-propagating high-temperature synthesis, with the pressure applied to the combustion products. The data, obtained by an experimental-theoretical investigation of impact resistance of protective barriers containing the above-mentioned materials in collisions with a spherical steel projectile, are presented. A better impact resistance of TiB₂ + B₄C cermets compared to that of Al₂O₃-ceramics is demonstrated. A possibility of prediction calculations of impact resistance of the specimens containing cermets in the range of collision rates under study is shown.
