摘要: Joining of composite, Al2O3-TiC, with heat-resistant 9Cr1MoV steel, was carried out by diffusion brazing technology, using a combination Ti, Cu and Ti as multi-interlayer. The interfacial strength measured shear testing the result explained fracture morphology. Microstructural characterization Al2O3-TiC/9Cr1MoV joint investigated X-ray diffraction (XRD) scanning electron microscope (SEM) energy-dispersion spectroscopy (EDS). results indicate that 122 MPa can be obtained controlling heating temperature at 1130°C for 60 min pressure 12 MPa. Multi-interlayer Ti/Cu/Ti fused fully occurred to produce layer between Al2O3-TiC steel. total thickness is about 100 μm Ti3AlC2, TiC, Fe2Ti are found occur in interface layer.
