Abstract
The joining between ceramics and metallic alloys can be analysed by three fundamentals aspects. - The thermodynamic aspects of physical chemistry and mechanic. - The kinetic aspects of the physical chemistry reaction. - The electrics aspects. On the outside specifics reactions physical chemistry and mechanical of junctions developped between ceramics and metallic alloys, the reactions is still in existence a function of the joining technical appliqued. It is distingued : - The method of junction by wettability of liquide metallic interlayer and junction by technical a solid state bonding. - The reactives and non reactives junctions. The work set out underline the different macromechanic, reactionnal aspects that can explain the adhesion between certain ceramics and metallic alloys. We study the influence of residual stresses, of the nature of components in the area of ceramic / metal interlayer on the life duration of junction.
