Abstract

Ceramic-ceramic joining methods that utilize microdesigned multilayer metallic interlayers are presented. The methods allow the formation of ceramic-ceramic joints with high melting point metals at temperatures that are generally several hundred degrees lower than those required for the most conventional diffusion bonding and brazing methods. The methods make use of a thin transient liquid phase layer to facilitate bonding. Examples of interlayer design strategies and successful interlayer designs are presented. An overview of processing parameters and results of flexure tests on alumina assemblies bonded with several distinct interlayer chemistries is provided. Effects of environmental exposure on the properties of joints are discussed.
