| Abstract | Using coke, together with SiC or B4C powders as raw materials, carbon/ceramic composites were prepared by a spark plasma sintering process of a short duration. The oxidation resistance of the composite containing B4C powder was higher than that of the composite containing SiC powder. The temperature at which the weight decrease of the composite containing 10 wt% B4C powder began shifted to the high-temperature side compared with that of the carbon material composed only of coke. Approximately 44% of the initial weight of the specimen remained even after thermogravimetric analysis in air up to 1000 o C. By X-ray diffraction analysis, diffraction peaks corresponding to B2O3 were observed. This finding indicates that B4C in the composite is oxidized to B2O3, which then forms an oxidation-resistant film, leading to an increase in the oxidation resistance of the composite. |
