Abstract: For developing TiO based imitated gold materials, the wettabilities of Fe and Fe-Cr-Ni-Ti onTiO were studied. The results indicated that the wettabilities of Fe and Fe-Cr on TiO were poor, and their wetting angles were about 90°at melting point. The wetting angles reduced with the increase of wetting temperature,but the influence of temperature was small. Fe and Fe-Cr containing Cr 50% or less could react with TiO on the interface to form Fe2Ti and Ti2O3, but this did not improve the wettability effectively. When Ni-Ti was added into Fe-Cr alloy, Ni3Tiwas formed on the interface, which can reduce the interface energy, improve the wettability, and preventthe formation ofFe2Ti andTi2O3. The wetting angles could go down to about40°when 3% Ni-Ti was added to Fe-Cr alloy.
