Summary

Special procedures have to be adopted to achieve successful brazing and this paper discusses the use of active metal brazes containing titanium. This component reacts to change the chemistry and properties of ceramic surfaces. Particular attention is drawn to the use of thermodynamic data in explaining wetting behavior, illustrated by reference to copper base brazes. Wetting is the first requirement for successful brazing, but it cannot be assumed that the joints will be strong. Nevertheless, the structural changes caused by melt-ceramic reactions can promote bonding and the maximum bonding can be related to the interface chemistry.
