The joints of Si3N4 ceramics bonded together with Fe-Ni/Cu/Ni/Cu/Fe-Ni inte
rlayers were compared with the joints bonded with Ti/Cu/Ni/Cu/Ti interlayer
s. The composition and the strength of eight kinds of joints were studied u
sing scanning electron microscopy (SEM), electron probe microanalysis (EPMA
). X-ray diffraction (XRD) and strength tests. It was found that the Fe-Ni
interlayers formed constantly strong joints with interfaces that were strai
ght with no distinguishable reaction layers. (C) 2001 Elsevier Science B.V.
