Wettability of TiAl Alloy on Calcia-Stabilized Zirconia

Abstract:

The wettability between liquid Ti-50Al (at.%) (TiAl) and calcia-stabilized zirconia (ZrO₂ (CaO)) in the gravity field and/or electromagnetic fields was studied in argon atmosphere. The results show that the equilibrium contact angle between liquid TiAl and ZrO₂ (CaO) decreased from 63° in the gravity field to 50° in the electromagnetic field. However, the time required for the system to achieve equilibrium in the electromagnetic field was 16s, which was longer than that in the gravity field. The effect of the electromagnetic field on the wettability between TiAl and ZrO₂ (CaO) was explained by the total free energy at the liquid/solid interface and activity of Ti element.
