摘要

The wetting behavior of liquid iron and steel on Al_(2)O_(3), MgO and Ti_(2)O_(3) 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 Al_(2)O_(3) and MgO substrates, reaction layers in form of FeAl_(2)O_(4) and MgO–FeO (solid solution) were formed. These layers slightly decreased the contact angle and surface tension values after a full melting. For a Ti_(2)O_(3) 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 Ti_(2)O_(3) substrate in contact with steel, the contact angle and surface tension values decreased steeply after a full melting, due to the formation Al_(2)TiO_(5) reaction layer formation at the interface.
