Effect of Sn-xTi/Al2O3 wettability with Ti addition

Abstract

Abstract: In order to solve a problem that addition of active element Ti is beneficial to improve wettability of metal/Al₂O₃ system, but the wettability mechanism is still unclear, the wettability of molten Sn-(0%,2%,5%) Ti alloy on Al₂O₃ surface in high vacuum at 973~1 273 K was studied by improved sessile drop method. The results show that increase of Ti content significantly improves the wettability ofSn-xTi/Al₂O₃ system. The reason for wettability improvement is that the adsorption of Ti at the interface reduces free energy of the solid/liquid interface, rather than the reaction product precipitated at the interface. For this conclusion, conducted experimental results are verified by a statistical thermodynamic model of adsorption, and it is proved that the spreading kinetics of Sn-xTi Al₂O₃ system is well controlled by the adsorption kinetics to a great extent.

Key words: wettability, spreading, adsorption, interfacial reaction
