Summary

The possibilities of application of the brazing technology for the manufacturing of ceramic joints are shown on examples of TiN particle reinforced Si3N4 and SiC fibre reinforced borosilicate glass composite joints. These composite materials were brazed to other ceramics or metals in a onestep process using active filler metals. In case of ceramic-metal joints the main attention was paid to the control of the residual stresses. Novel filler metals were developed to minimize the residual stresses and to improve the joint. Numerical and experimental methods were applied to evaluate the residual stress state in the joints. The joints were characterised in their temperature service range in bending- and tensile- tests. The characterisation of the thermo-mechanical behaviour was accompanied by fractography work. The influence of the filler metal, of the specimen preparation (especially chamfering), processing parameters and joint design on the joint strength were studied. To clarify these effects, the microstructure of the joints, especially of the brazing zone was characterised.
