The nano-wetting aspect at the liquid-metal/SiC interface

Abstract

The wetting process on the nano-scale, as an initial and essential step in liquid metal/ceramic joining, is discussed here. Thanks to recent breakthroughs in experimental techniques with nanometre resolution, questions posed several decades ago are being looked at again. Despite recorded facts on acting mechanisms, the published results are very diverse due to the variety of materials and their structures, as well as experimental conditions, so the modeling is inevitable for process development and to overcome the multi-scale influencing parameters issues. A nano-scale wetting model have been proposed and tested on results obtained in a liquid-metal/SiC system that was published in the literature.
