Investigation Wetting Mechanism at Al-Mg/Ceramic Interfaces

The wettability at the metal – ceramic interfaces is important in many applications، such as metal matrix composites (MMCs). The objective of the present paper is to study wetting phenomenon of aluminium base on reactios at interfacial. The effects of alloy elements such as Mg and the processing temperature on wettability were investigated theorically. The reactive wetting is governed not only by the interfacial reaction intensity،، but also by the physical and chemical properties of the resulting interface،. The calculated wetting contact angles from physical and chemical model are approximately in agreement with experimental values.
