Abstract
Diffusion bonding Al2O3-TiC ceramic matrix composites with Cr18-Ni8 austenitic stainless steel has been performed with a Ti/Cu/Ti multi-interlayer. The Al2O3-TiC/Cr18-Ni8 joints were characterized by means of scanning electron microscope (SEM) with energy-disperse spectrometry (EDS), electron probe microanalysis (EPMA) and X-ray diffraction (XRD). The results indicate that the Al2O3-TiC/Cr18-Ni8 diffusion-bonded joint with shear strength of 106 MPa was obtained by using the Ti/Cu/Ti multi-interlayer. An interfacial transition zone was formed by diffusion reaction between Ti, Cu and the elements from the substrates, Al2O3-TiC and Cr18-Ni8. TiO, TiC, α-Cu, CuTi, FeTi and Cr2Ti are produced near the interface of the Al2O3-TiC/Cr18-Ni8 joint.
