Ti48Al2Cr2Nb alloys and ZrB₂-SiC ceramics were brazed with Cu_41.83Ti_30.21Zr_19.76Ni_8.19 (at.%) amorphous alloy filler.The microstructure and mechanical properties of the joint were analyzed by scanning electron microscopy,energy spectrometer,X-ray diffraction and testing machine.The results show that the typical joint interface structure of TiAl alloy and ZrB₂-SiC ceramic brazed joint is:TiAl/Ti₂Al/AlCuTi/(Ti,Zr)₂(Cu,Ni)+TiB+TiCu/Ti₅Si₃/ZS.When the brazing temperaure is 910 ℃,the width of the reaction layer near the ZrB₂-SiC side increases gradually with the increase of the holding time,and the TiB and TiCu aggregates in the diffused part of the joint grow.The joint shear strength increases first and then decreases with the increase of holding time.When the brazing temperature is 910 ℃ with holding time of 20 min, the joint shear strength reaches the maximum value of 187 MPa.Through the fracture analysis of each process,it is found that the joints are all broken on the ceramic side,and the fracture mode is brittle fracture.
