The ability to make quantitative statements concerning cavitation damage should involve appropriate measurements of both material loss and material damage. This study investigates the extent to which surface profilometry techniques can be used to determine cavitation damage characteristics by obtaining the surface profiles of test specimens before and after cavitation. Based on the maximum depth of penetration obtained from the surface profiles, the velocity exponent for maximum damage is determined. This value of the exponent agrees favourably with previously published values obtained from weight loss measurements.
