A NEW FACILITY FOR EVALUATION OF MATERIALS SUBJECT TO EROSION AND CAVITATION DAMAGE

Abstract

A new type of test facility for simulating accelerated cavitation damage is described. The facility consists of a rotor with a material specimen attached at the periphery in such a manner that there is repeated impact with a column of liquid droplets during high-speed rotation of the specimen. Preliminary tests indicate that erosive weight loss from the specimen is similar in character to that produced by other cavitation damage facilities. A refined ability to control impact conditions permits detailed study of the failure mechanics.
