    Abstract

    The wetting behavior of liquid iron and steel on Al2O3, MgO and Ti2O3 substrates was measured by using the sessile drop method. Measurements were carried out using a controlled oxygen partial pressure and using an argon protected atmosphere. For the Al2O3 and MgO substrates, reaction layers in form of FeAl2O4 and MgO-FeO (solid solution) were formed. These layers slightly decreased the contact angle and surface tension values after a full melting. For a Ti2O3 substrate in contact with pure Fe, no-reaction could be observed at the interface. Furthermore, the contact angle and surface tension values were almost stable after a full melting. For a Ti2O3 substrate in contact with steel, the contact angle and surface tension values decreased steeply after a full melting, due to the formation Al2TiO5 reaction layer formation at the interface.
