    • Abstract


      Although a strong thermo-compression bond is formed between some metals and ceramics, the bonding mechanism is not clearly understood. In the present work57Fe Mössbauer spectroscopic study of (Al2O3 + Fe) cermet is carried out to investigate the reason of adherence at the metal-ceramic interface. The isomer shift, quadrupole splitting and linewidths of Mössbauer spectra indicate that a compound of the spinel type FeO·Al2O3 is formed but the site symmetry around Fe may be locally distorted by a small amount as compared to that for stoichiometric FeAl2O4.
