ResumoThe resistance of a material to cavitation erosion is assessed by measuring specimen weight change induced by the application of a high-power vibration horn close its surface. This paper describes a proof-of-concept study of a measurement technique for assessing the progression of cavitation erosion for commonly used engineering materials. UK National Physical Laboratory Cavitation Sensor enabled the generated acoustic signals produced by inertial cavitation collapse. Results suggest that acoustic emission monitoring shows promise as a tool which can be employed to quantitatively record the stability of the applied cavitation erosion stimulus.
