It was previously reported by the authors that the cutting performance of TiC, SiC and SiC whisker contained Al2O3 based black ceramics was quite unique and different in each other. Then the properties of combined ceramics having 25vol% of SiC and TiC were studied. It was found that the properties such as strength, resistance to oxidation, interfacial reaction between ceramics and work, and cutting performance for S48C and Inconel 600 were regularly changed according to SiC/TiC volume ratios. The reason was in the fact that, in combined black ceramics, SiC and TiC parTiCles coexisted in the structure, and mullite and Al2TiO5 also coexisted in the scale.
