The wetting behavior of molten Zr55Cu30Al10Ni5 on Al2O3 and ZrO2 was studied using the sessile drop method. The results show that the nonwetting-to-wetting transition for the Zr55Cu30Al10Ni5/ZrO2 wetting system takes place at 1193 K. The wetting of molten Zr55Cu30Al10Ni5 on Al2O3 is a non-reactive wetting. Owing to the formation of diffusion band at the front of the wetting tip in the Zr55Cu30Al10Ni5/Al2O3 system, the wettability of Al2O3 is better than that of ZrO2.
