Zusammenfassung:PURPOSE:To remove voids and allow the title substance to have excellent wear resistance by a method wherein Si is added in a suitable amount to a composite ceramics made of TiC and Al2O3, and further one or more kinds of B and C are added in a suitable amount. CONSTITUTION:Si is added in 0.05-5pts.wt. to the 100pts.wt. of the composite ceramics made of TiC at 20-55wt% and the remnant Al2O3. Thereby, the strength of interface between TiC and Al2O3 particles increases. Next, one or two kinds of B and C are added thereto in 0.05-2.0pts.wt. The addition of these elements results in the remarkable improvement of the wear resistance of the ceramic composition. Further, one or more kinds of Fe, Cr, and W are added thereto in 0.05-5pts.wt. This manner enables the crystals of Al2O3 and TiC particles to be stronger.
