The evaluation of the wear resistance of a material to cavitation erosion using an ultrasonic vibratory apparatus can be found in ASTM standard G32-06. The definitions of terms (incubation time, maximum erosion rate, cumulative mean depth of erosion, etc.) can also be found there. The incubation time, maximum erosion rate and cumulative mean depth of erosion are derived from a cumulative mass loss–time curve. The measurement on the mass of the sample tested should be accurate. In recent years, surface roughness [CHI 05] and area fraction of cavities of the eroded surface [DUL 04] have provided useful information for the incubation stage.
