Boron nitride (BN) and silicon carbide (SiC) coatings were prepared in sequence on desized SiC tows by chemical vapor infiltration (CVI) at the temperature of 950°C. BN was synthesized by the reaction between boron trichloride (BCl 3 ) and ammonia (NH 3 ) while SiC was from the thermal decomposition of methyl trichlorosilane (MTS).
