Joining of Si(3)N(4) ceramics with transition metal interlayers
The bonding of Si(3)N(4) ceramics has been investigated, using thin transition metal and alloy interlayers as joining agents, via either solid or liquid state. Joining conditions varied according to the selected interlayer materials, which were Ni, Cr, Fe, Ni-Cr, Fe-Cr for diffusion bonding and Ni-Cr-Si for brazing. Joints with high strength have been manufactured under optimised solid state bonding procedures. The microstructure of the joint interface has been characterised by optical microscopy (OM), electron probe microanalysis (EPMA), scanning electron microscopy (SEM) and X-ray diffraction (XRD) in an effort to determine the influence of the different bonding and interlayer material parameters. Amongst the different elements present in the interlayers, Cr was found to be the most active.
