摘要：

针对连续SiC纤维增强钛基复合材料界面反应速率、反应产物进行了研究。采用基体-纤维涂覆法和热等静压工艺，制备了连续W芯SiC纤维增强TC17复合材料。对复合材料进行不同温度、不同时间热暴露，通过SEM、TEM、EDS，表征分析了界面反应层厚度、界面处化学成分及界面反应产物类型。结果表明：C涂层能有效保护SiC纤维；界面反应层处的主要元素为Ti和C；制备状态试样的界面反应产物为TiC1-x，靠近C涂层的TiC1-x晶粒较细小，靠近基体TiC1-x晶粒较粗大；高温热暴露使界面反应加剧，反应层厚度增加，反应层的生长符合抛物线规律，反应的动力学参数为频率因子k0=1.33×10-3m·s-1/2，反应激活能Q=243.22 kJ·mol-1。

It was studied the interface reaction rate and product in continuous SiC fiber reinforced Titanium composite. The continuous W core SiC fiber reinforced Ti17 composite was fabricated by HIP technology through matrix-fiber coated method, and then the composite was exposed to various temperatures and time. The thickness of the interface reaction layer, the chemical component and the reaction product of the interface were observed and analyzed by Scanning Electron Microscopy(SEM), Transmission Electron Microscopy(TEM) and Energy Design Suite(EDS). The results demonstrate that the carbon coating can protect the SiC fiber efficiently, and the main elements in the interface reaction layer are Ti and C. Furthermore, the interface reaction product of as-processed sample is TiC1-x , which has a fine grain size near the carbon coating and coarse grain size near the matrix. Thus, the interface reaction and its layer thickness increase after thermal exposure, the growth of the interface layer obeys parabola law, and the kinetic parameters are frequency factor k0=1.33×10-3 m·s-1/2 and activation energy Q=243.22 kJ·mol-1， respectively.
