Brazing is a joining technique that can be applied to sintered materials in the manufacture of metal-metal and metal-ceramic components with high complexity. The production of sound joints requires the use of an appropriate filler alloy along with the optimization of process parameters, such as brazing temperature and time. In addition, the open pores can act as canals removing the filler alloy from the interface by a capillary effect, which is detrimental to the joining process as well as to corrosion behavior of the substrate. In this study, sintered Fe-Cu pellets were brazed together using Ag-based commercial alloys. In addition, alumina (Al2O3) was brazed to low-expansion alloys (Fe-Ni-Co). Such alloys were produced by powder metallurgy in order to adjust the coefficient of thermal expansion of the material to that of Al2O3 through an accurate control of their composition. in metal-ceramic bonding it is important to reduce the thermal expansion mismatch between the materials, thus minimizing the presence of thermal-mechanical stresses and improving the mechanical reliability of the joints.
