This work assessed the fundamental characteristics of multifunction cavitation (MFC) through both theoretical and experimental investigations. Ultrasonic irradiation of a water jet during floating cavitation was used to generate microjets with hot spots and this MFC process was employed to perform hot work on titanium oxide (TiO_2) particles as well as an ITO (Indium Tin Oxide) film on soda-lime glass and a steel surface. The processed TiO_2 particles were found to have modified surface morphologies and electrochemical surface conditions which improved their photocatalytic activity. It was also observed that the ITO film could be removed by MFC and that this process remarkably decreased the outgassing of carbon steel.
