摘要

Examples of joining techniques applied to various ceramic materials are presented and related to the principal features that must be controlled in order to realize a reliable bond. Adhesion between two ceramic materials can be obtained by exploiting their specific microstructural and compositional characteristics. In particular, the interfacial forces, that act during the sintering process and determine the final microstructure of the materials, play an important role even during bonding. The intergranular force balance change with temperature, applied pressure and in the presence of new compounds. Moreover, when a liquid phase that wets well the main ceramic phase is involved in a bonding process, adhesion can be promoted by the capillary force that arises at the meniscus between two surfaces in contact. The consequent interaction between the ceramic grains at the interface and the liquid phase determines the final microstructure and properties of the joint. Results are presented for oxide (AL_2O_3, ZrO_2 and AL_2O_3/ZrO_2 composite) and non oxide (Si_3N_4 and SiC) dense ceramics, bonded with a metal or a glass interlayer or with no interlayer, with or without an applied pressure. The chemical stability and the mutual mobility of the phases involved are investigated. The microstructure of the interfacial region is analysed and related to the flexural strength values and other mechanical and compositional features of the materials.
