Effects of Brazing Parameters on Microstructures of C/C Composite/Cu/Mo/TC4 Brazed Joints
摘要
Abstract
C/C composite and TC4 were brazed using TiZrNiCu filler metal and Cu/Mo composite in-terlayers at 820-940℃ for l-30min. The interfacial microstructures were investigated by scanning electron microscopy and electron energy spectrum analysis. The results showed that the sequence of the interface structure at low brazing parameters can be described as the following: Cu/Cu51Zr14/Ti2 (Cu, Ni)+Ti(Cu,Ni)+TiCu+Cu2TiZr/TiC/C/C composite. With the increased brazing parameter, TiCu and Cu2TiZr disappeared, and Ti(Cu,Ni)2 appeared. The interface structure was changed to Cu/Cu5i Zri4/Ti2 (Cu,Ni)+Ti(Cu,Ni)+ Ti(Cu,Ni)2/TiC/C/C composite. For high brazing parameters, the interface structure was composed of Cu/Cu51 Zr14/Cu(s. s) + Ti(Cu, Ni)2/TiC/C/C composite. The thickness of Cu51Zr14and TiC reaction layers increased with the increased brazing temperature and the prolonged holding time.关键词
