Abstract

Fabrication of composite materials is considered. Porous preforms from reaction-sintered silicon nitride (RSSN) and RSSN with SiC particles have been infiltrated with CaF2 and CaSiO3 melts at a temperature of 1450 and 1600‡C, respectively. The wear resistance of the composite (with infiltrations) materials turned out to be much higher than that of original (without infiltrations) materials of the RSSN and RSSN — 50% SiC type. A composite material with the composition RSSN — 50% SiC — CaSiO3 is shown to possess the highest hardness and abrasive resistance.
