β-SiAlON-BN Composites by Infiltration-Mediated SHS under High Pressure of Nitrogen Gas

摘要

Infiltration-mediated SHS of β-Si_(6-z)Al_zO_zN_(8-z)— BN composites was explored upon variation in applied nitrogen pressure, amount of combustible and low-melting components in green mixture, sample size, and BN content of resultant composites. Synthesized ceramic composites of different density and BN content were characterized by their strength parameters, tribological behavior, and thermal shock resistance.
