Effects of experimental conditions of the vibratory erosion test upon the damage caused by cavitation erosion of metals were investigated. By use of a dimensionless number as a quantitative criterion of cavitation damage, the following conclusions were obtained. (1) Amplitude of vibration and diameter of test specimen exert decisive influence on the rate of erosion but not at all on the degree of damage. Temperature and pH of test liquid (corrosiveness of the test liquid), frequency of vibration and pre-strain on the specimen have influences on the degree of damage as well as on the rate of erosion. (2) In a vibratory cavitation erosion test it is quite feasible that damage may be caused to metals by any desired mechanism. Some characteristic features of damage were also revealed.
