摘要	The wetting behaviours and interface reactions in Ti32.8Zr30.2Ni5.3Cu9Be22.7/Al2O3 system were investigated using a sessile drop technique at 1073-1223 K in high vacuum. Both the equilibrium contact angles and the interface reactions largely depend on the test temperature. The equilibrium contact angle first decreases and then increases with the increase in temperature. The minimum of the equilibrium contact angle is 21 degrees at 1143 K. The reason for the anomalous change of equilibrium contact angle is the change of the interface structure. At low temperature, the adsorption of alpha-Ti solid solution at the interface and the formation of Ti0.5Zr0.5O0.33 in the precursor film are beneficial to the wettability. With further increasing the temperature to 1173 K, the formation of ionic alpha-BeO is responsible for the deterioration in wettability.
