| 摘 要： | 利用放电等离子烧结(SPS)对碳化钛(TiC)/氢化钛(TiH2)混合粉末进行烧结以制备块材。利用X射线衍射(XRD)并结合Rietveld精修法对块材进行定性与结构分析;借助扫描电子显微镜(SEM)对块材断面微观形貌进行观察;测试了块材硬度并探讨SPS技术制备TiC块材的致密化过程与反应机理。结果表明:混合粉末经SPS烧结,获得了高度致密的TiC块材;与传统烧结方法比较,SPS技术更具低温快速性。

| Abstract: | In this work,the blended powders of titanium carbide(TiC) /titanium hydride(TiH2) are sintered by spark plasma sintering(SPS) in order to prepare TiC bulk.The qualitive and structural analysis are realized by X-ray diffraction(XRD) combined with Rietveld refinement.Furthermore,the micrographs of the fracture surface is characterized by scanning electron microscopy(SEM).Then,the hardness is measured and the densification and reactive mechanism of TiC bulk prepared by SPS technology are discussed.The results show that the TiC bulk with good densification is prepared by SPS with the starting materials of blended powders.Compared with traditional sintering methods,the SPS technology is of lower sintering temperature and less time. |
