Wetting phenomena in materials processing

It is well known the wettabilities of liquids by solids play an important role in materials manufacturing including iron and steelmaking. Non-wetting systems are required in some cases such as deoxidation process in steel making and wetting ones are sometimes desired to fabricate high quality metal matrix composites. In this meaning it is necessary to control the wettability to produce nigh quality materials. III this paper, factors affecting the wettability are described and how the wetting phenomena affect in materials manufacturing process, especially in deoxidation process and solidification process of steel are reviewed.
