It was rationalized, with limited supporting evidence, that
most damage due to cavitation stems from cavities which are the
consequence of outgassing nuclei growing from fissures in a body's
surface. To minimize this damage, it was proposed that body
surfaces be treated to reduce the number and activity of these
surface faults. Vibratory cavitation damage tests of specimens
treated to seal, neutralize, or compress the test surface indicated
that these protective measures were inadequate for the severe
conditions of a vibratory test.
Light shot peening of a work hardening stainless steel prior
to cavitation exposure substantially reduced the normal rate of
