抄録
The effects of temperature and oxygen on the wettability of alumina substrates by liquid iron were measured at the temperature range from 1823K to 2023K over the wide range of oxygen concentration up to 0.08mass% by use of the sessile drop method. Obtained results are as follows;(1) Contact angle of liquid iron on alumina substrate decreases with increasing oxygen concentration in liquid iron, but does not change with temperature.(21 Work of adhesion between liquid iron and aulmina substrate decreases with increasing oxygen concentration, but does not change with temperature.(3) Above 0.04mass% of oxygen concentration in liquid iron, contact angle and work of adhesion are kept to bo nearly constant and hercynite (FeO・Al203) was identified at the interface between liquid iron and alumina substrate by X-ray method. It was estimated from work of adhesion and interfacial excess quantity for oxygen that oxygen ion existed at the interface with close-packing.
