Abstract

Nitride ceramics are gaining importance in advanced technology applications. Examples include high temperature engine components of Si(3)N(4), heat dissipating electronic substrates of AlN, and chemically inert cutting tools of cubic BN. The effective and widespread use of nitrogen ceramics in these and other applications, however, depends on the ability to bond them to metals and to themselves as well as to other ceramics. The successful production of reliably strong joints by diffusion bonding and brazing with reactive filler metals is discussed. Reference is made to the joining of AlN, BN and particularly Si(3)N(4) using alloys containing reactive elements, and comments made on the influence of process and parameters such as temperature, environment and ceramic surface preparation on the microstructure, mechanical properties and high temperature stability of interfaces.
