Vibratory tests, cavitation damage

Vibratory test apparatuses are relatively cheap to build and run, and have low power consumption, while flow rigs are bulky, expensive to build and run, and have high power consumptions but have the advantage that they simulate more closely practical conditions of hydrodynamic cavitation. On the other hand, the damage rate is higher in the vibratory tests than in the... 

ASTM G 32, Method for Vibratory Cavitation Erosion Test— This standard presents a test method for determining the susceptibility of an alloy in an electrolyte to cavitation damage using high-frequency vibration. In general, the rate of erosion is determined by weight loss of the specimen. The method contains terminology definitions, a description of the apparatus, test specimen dimensions and preparation, test conditions, test procedures, interpretation of residts, and report considerations. 

ASTM G 32-98, Test Method for Cavitation Erosion Using Vibratory Apparatus [13], describes a standard method for performing cavitation tests. Its scope is listed as follows "This test method produces cavitation damage on the face of a specimen vibrated at high iiequency while immersed in a liquid. The vibration induces the formation and collapse of cavities in the liquid, and the coUapsirrg cavities produce the damage to and erosion (material loss) of the specimen. ...
