Interfacial Wetting Behavior under Low-Density Ultrasonic Field and Solvent - Assisted Wet Condition
In this paper, the author had adopted the low-density ultrasonic field coupling method, coupled the ultrasonic directional beam to metallic melt, and then coupled energy to C/Al interface by sound propagation, eventually accomplish C/Al interfacial wettability and interfacial reaction by using ultrasonic field coupling method, and synthesize Al-Ti-C master alloys by using the same method. Some experiments showed that in the low-density ultrasonic field and under flux auxiliary wetting, there is no explicit incubation period in the prophase of wetting, in the medium term of wetting, the wetting angle between aluminum melt and carbon will reduce with time extension, however, the wetting spreading radius will increase with the extended holding time, and reach wetting balance state in 20 minutes. In the condition of 1023K, the equilibrium wetting angle is less than 22°,and wetting spreading radius is close to 20mm.
