Development of Large-size Ultrasonic Sonotrodes for Cavitation Treatment of Molten Metals
Abstract
This work presents results of the development of large-size high-amplitude ceramic sonotrodes destined for use in cavitation treatment of molten metals. The sonotrodes were characterized for their vibration amplitude, erosion resistance and cavitation-producing ability in aluminum melts. The ability of the sonotrodes to refine the grain structure was examined by applying them to the DC casting of Al-Si hypereutectic alloys. The results showed that the sonotrodes have excellent performance characteristics, and they possess far superior erosion resistance and endurance than those made of such high-resistance refractory metals as Nb alloys.
