Interfacial Properties of Dilute Fe-O-S Melts on Alumina Substrates.

Abstract

Compilations and data pertaining to the wettability and interfacial properties of Fe-melts and dilute Fe-O-S alloys on alumina substrates have been collected and compared. The properties included the surface tension of liquid Fe; the surface tension of Al2O3; measurements of work of adhesion and contact angles; and the effects of sulfur and oxygen on the surface tension of liquid Fe and on the contact angle. Based on the comparisons, recommendations for estimating these interfacial properties as well as the tension of the Fe-O-S (liquid)/Al2O3 interface are given.
