The constitutive response of brazing alloys and the residual stresses in ceramic-metal joints

Nowadays the joining of dissimilar materials is often the only solution to fulfill the complex requirements of high technology applications. One of the fields in which the research activity is more intense and promising is that of the brazing of ceramics w ...

Solid freeform fabrication of porous ceramic parts from ceramic powders and preceramic polymers

Thomas Alexandre

This dissertation addresses the development of a Solid Freeform Fabrication process, Selective Laser Pyrolysis, to fabricate three-dimensional porous ceramic preforms from ceramic powders and preceramic polymers. It contributes to a better understanding of ...

Selection and design of brazing fillers for metal-ceramic joints

Matteo Galli

Three different approaches for metal to ceramic brazing are compared using the example of Si3N4/TiN-steel joints: the use of an active filler metal (single layer brazing system), the metallisation of the ceramic and brazing with a non active filler (two-la ...

Effect of thick-film materials on the mechanical integrity of high-strength ceramic substrates

Peter Ryser, Thomas Maeder, Caroline Jacq, Giancarlo Corradini

Recently, high-strength zirconia-toughened alumina (ZTA) ceramic substrates have attracted interest, because they offer much improved mechanical properties over straight alumina, while maintaining advantages such as good thermal conductivity and chemical s ...

Strength of ceramic substrates for piezoresistive thick-film sensor applications

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol

Force and pressure sensors based on the piezoresistive properties of thickfilm resistors are widely used due to their reliability, simplicity and lowcost. Recently, the introduction of low-temperature co-fired ceramic(LTCC) substrates has allowed further i ...

High temperature deformation mechanisms of cemented carbides and cermets

The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...

Microfabrication of ceramic components by microstereolithography

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technique that allows the manufacture of small and complex three-dimensional (3D) components in plastic material. Many of the components produced by this technique are too small and too complex to be replicated by molding and, c ...

Manufacturing of zirconia microspheres doped with erbia, yttria and ceria by internal gelation process as a part of a cermet fuel

Manuel Alexandre Pouchon

Zirconium oxide is an inert matrix candidate for the transmutation of plutonium in light water reactor (LWR). The thermal conductivity of cubic zirconia is however lower than the conductivities of UO2 and MOX. Special designs are therefore necessary to avo ...

High-strength ceramic substrates for thick-film sensor applications

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol

Force and pressure sensors based on the piezoresistive properties of thick- film resistors have recently found wide application due to their low cost, reliability, and relatively good precision. Achieving high elastic mechanical strains is important to max ...

Analysis of porous features in zirconia based inert matrix, impact on the material qualification

Manuel Alexandre Pouchon, Marco Streit

Pore size distribution, porosities and consequently derived densities are key parameters for the qualification of inert matrix fuel (IMF). Porous features must be determined accurately for assessing the in-pile behaviour of the fuel. The analytical methodo ...
