Abstract:
Boron carbide powders were ground in a planetary ball mill, and the mixtures of various size fractions were compacted by uniaxial dry pressing. A green density of 75 % of the theoretical was achieved. Upon infiltrating B4 C framework with molten silicon, a non-porous composite is formed with a density of 2.45–2.55 g/cm3 and hardness of 22–27 GPa. As a result of the introduction of 1–5 % MWCNTs (multi-walled carbon nanotubes), the green density of the compacts decreases, however, the strength of the infiltrated material increases significantly. The effect is due to the formation of platelike SiC crystals as a result of the interaction of nanotubes with silicon.
