An experimental study using pulsed ultrasonic technique to investigate the effect of the cavitation on Zn probes is reported. The difference of potential between two Zn electrodes one in the focal zone and the other out of it, the intensity of sonoluminescence and that of subharmonic emission, have been measured at 0.7 MHz by varying the transducer voltage and the other two pulse parameters. A correlation between these data under the difference stages of cavitation is observed, which may lead to the understanding of the mechanisms of the sonoluminescence and of the erosion.

Abstract
An experimental study using pulsed ultrasonic technique to investigate the effect of the cavitation on Zn probes is reported. The difference of potential between two Zn electrodes one in the focal zone and the other out of it, the intensity of sonoluminescence and that of subharmonic emission, have been measured at 0.7 MHz by varying the transducer voltage and the other two pulse parameters. A correlation between these data under the difference stages of cavitation is observed, which may lead to the understanding of the mechanisms of the sonoluminescence and of the erosion.File in questo prodotto:
