The structure of the surface layer of ceramic composite materials (CMC) of the compositions HfB 2 & # 8211; SiC and SiC & # 8211; TiC after exposure to a flow of dissociated air has been investigated. ...
Materials based on Si 3 N 4 -BN were obtained by liquid-phase sintering using 20 & # 37; (by volume) YAG as a sintering aid. To obtain composite materials, we used boron nitride powders of hexagonal ...
