中文摘要：本文以Ti和C的片状材料为原料，利用放电等离子烧结（SPS）技术烧结制备了具有层状结构特征的Ti/TiC/C复合材料，研究其反应界面的性质和状况，并讨论了烧结温度对界面反应层的影响。研究结果表明：采用放电等离子烧结技术可以制备出Ti/C叠层复合材料，其界面反应的程度与烧结温度有关，随着烧结温度升高，反应层的厚度增大，烧结温度达到1500°C时界面反应程度较好，反应层的厚度可达到32.6µm，进一步提高烧结温度，将会使得Ti发生熔化现象，无法得到Ti/C叠层复合材料。
英文摘要：The laminated structure of the TiC/Ti composite materials with the sheet of Ti and C as raw materials was prepared by spark plasma sintering (SPS) technology. We studied the characteristics and conditions of interfacial reaction and discussed the effects of sintering temperature on the reaction layer. The results show that: Using spark plasma sintering technique can be prepared Ti/C laminated composite materials. The extent of interfacial reaction related to the sintering temperature and the thickness increased with the temperature. When the sintering temperature at 1500°C has better degree of interfacial reaction and the layer thickness was up to 32.6μm. The Ti will melting with the sintering temperature improved and thus can not obtain Ti/C laminated composite materials.
