“…For joining of ceramics several techniques are available including solid-state diffusion bonding [1], friction joining [2], laser welding [3], ultrasonic joining [4], and brazing [5]. Most of these joining processes involve high temperatures which may be detrimental for components with heatsensitive properties.…”

In this study, Al 2 O 3-ceramics were joined via TLP bonding using interlayers of eutectic Au-12Ge (wt%) and Au-3Si (wt%) solder alloys, respectively, with a melting temperature of 361 and 363°C and Ni wetting layers. The Ni layers were part of a metallic multilayer coating (Ti/W/Ni) applied on the ceramic surface to ensure wetting and adhesion during the joining process. For comparison, a soldering process was performed as well by changing the multilayer structure to Ti/W/Au. With respect to the different joining processes the influence of the variation in wetting layers on the interface reactions, mechanical properties and re-melting temperature was analyzed by scanning electron microscopy, shear testing, and differential scanning calorimetry. It is shown that sound joint can be produced at a joining temperature of 400°C, achieving reasonable shear strength and re-melting temperatures more than 550°C above the initial melting temperature of the filler metal.

“…In practice, the situation is not so simple, as witnessed by the reduced interfacial contact and cracking sometimes seen in joined systems [10][11][12]. The organic vehicle can then be removed from the whole and the assembly sintered.…”

This paper reports part of an attempt to harness the scope and versatility of polymer manufacturing operations and use them in ceramics processing. It describes the preparation of extruded zirconia ridged plates, the film-blowing of zirconia and the solvent welding of stacks of these components to produce cross-flow structures. Assemblies of this type, prepared from a single ceramic, find application in heat exchangers. Assemblies of composite ceramics, when the problems of cofiring of different powders are overcome, provide solid oxide fuel cell structures. The organic vehicle used for these processes was based on polystyrene. The structures were sintered and then examined for the defects which are characteristic of these plastic-forming operations when applied to ceramics.
