Abstract
The cavitation-pitting tests described in this paper were made with an accelerated-cavitation machine of the vibratory type. An attempt was made to solve some of the phenomena of cavitation by varying the amplitude of vibration, by varying the depth of submergence of the test specimen in the test liquid, and by using alkalis, acids, and oils for the test liquid. Other tests were made to determine the relative resistance to pitting of recently developed materials and techniques for applying these materials. Results showed that accelerated-cavitation tests can be used to determine some of the mechanics of cavitation, as well as to indicate that some of the newly developed materials might be suitable for use on hydraulic machinery under operating conditions where cavitation occurs.
