Wetting, spreading and joining in the alumina-zirconia-Inconel 738 system

A study is presented on the wetting and spreading behaviour of Ag-Cu-Ti on zirconia and alumina-zirconia ceramics and on the Inconel 738. The results are discussed in terms of thermodynamic and kinetics of spreading, and on the basis of the morphological analysis, including microhardness tests, of the interfacial layers, both in the wetting couples and in the different joints.
