Scaling of cavitation erosion progression with cavitation intensity and cavitation source

► Several materials were eroded using two methods and various cavitation intensities. ► Material characteristic time and depth enabled all data to collapse on one curve. ► A simple mathematical expression was found to describe depth of erosion versus time. ► Characteristic parameters' dependency on cavitating jet pressure was obtained. ► Relative erosion resistance of some tested materials depends on cavitation intensity.
