摘　　要：The wetting behavior of molten Zr55Cu30Al10Ni5 on Al2O3 was studied by the sessile drop method in high vacuum. The results show that wetting kinetic at 1 163 K is composed of three stages: incubation, quasi-steady decrease and trend constant. Precursor film forms surrounding the wetting tip when wetting temperature is above 1 163 K. Formation of precursor film is related to the change of triple line configuration and results in good wettability. Chemical reaction dos not occur at the wetting interface. Al2O3 is an excellent reinforcement for Zr55Cu30Al10Ni5 matrix composite in terms of wettability and reactivity. The kinetic relationship of spreading ratio with spreading time was also investigated.The wetting behavior of molten Zr_(55)Cu_(30)Al_(10)Ni_5 on Al_2O_3 was studied by the sessile drop method in high vacuum.
