摘　　要：以连续陶瓷Si C纤维和TA2箔材为原材料,采用箔-纤维-箔方法,通过真空热制造技术制备了不同参数的连续陶瓷Si C纤维增强Ti基复合材料。利用光学显微镜、扫描电镜和能谱分析仪对制备态复合材料微观组织和元素分布进行了分析。结果表明,当真空热制造工艺参数为900℃/30 min/45 MPa时,复合材料增强体陶瓷Si C纤维与韧性基体Ti实现了理想冶金结合,Si C纤维以层状形式等距均匀分布于基体材料中,纤维轴向间距为200μm,复合材料体积分数为36.82%,陶瓷Si C纤维与基体Ti金属界面层厚度为0.8μm,界面处C元素呈抛物线分布,Si元素和Ti元素分别呈单向递减和单向递增分布。Taking continuous ceramic Si C fiber and TA2 foil as raw materials,by means of the foil-fiber-foil method,continuous ceramic Si C fiber reinforced Ti matrix composites with different parameters were prepared.The microstructure and element distribution of the fabricated composites were analyzed by optical microscope,scanning electron microscope and energy disperse spectroscopy.The results show that when the process parameters of vacuum thermal manufacturing are 900℃/30 min/45 MPa,the composite reinforcement ceramic Si C fiber and the ductile matrix Ti realize the ideal metallurgical combination.The Si C fiber is evenly distributed in the matrix material in the form of layer,the axial spacing of the fiber is 200μm,the volume fraction of the composite material is 36.82%,and the thickness of the interface layer between ceramic Si C fiber and the Ti matrix metal is 0.8μm.At the interface,the C element is parabolic distributed,and the Si element and Ti element are distributed in unidirectional decreasing and unidirectional increasing respectively.
