摘要
For developing TiO based imitated gold materials, the wettabilities of Fe and Fe Cr Ni Ti on TiO 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 Fe 2Ti and Ti 2O 3, but this did not improve the wettability effectively. When Ni Ti was added into Fe Cr alloy, Ni 3Ti was formed on the interface, which can reduce the interface energy, improve the wettability, and prevent the formation of Fe 2Ti and Ti 2O 3. The wetting angles could go down to about 40° when 3% Ni Ti was added to Fe Cr alloy.
