Abstract
Nano-porous titanium carbide (TiC) coating was in-situ synthesized by titanium tetrachloride (TiCl4) vapour based on silicon carbide (SiC) fibre substrate. The microstructure of the coating was characterized and the reaction process and growth mechanism of terraced TiC grains were analyzed. The coating consists of TiC nanograin and the nanopores are formed by the lateral stack growth. The supersaturation of gaseous reagents at the boundary layer controls the composition and the morphology of the coating. The SiC fibre covered by the optimized TiC coating preserves the original flexibility. Finally, the SiCf/SiC mini-composite with nano-porous TiC interphase was prepared. The fracture surface exhibits fibre pull-out and interphase fracture.
