Cavitation erosion using vibratory

ASTM Standard G-32. Standard method for cavitation erosion using vibratory apparatus. ASTM Volume 03.02, Wear and Erosion Metal Corrosion, ASTM, Philadelphia, PA (1993). 

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. ...

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. 

As noted earlier, cavitation erosion test methods such as the vibratory method (Rg. 6) have also been used to screen materials for service under liquid impingement conditions.
