The detailed characteristics of pitting in the early phases of cavitation damage incurred by test specimens inserted into the diffusing portion of a cavitating venturi are shown pictorially and discussed in terms of degree of cavitation, fluid, material, duration, and velocity effects. Quantitative damage results are presented from these tests for mercury and water as test fluids and for a variety of test materials. Various possible damage correlating parameters are discussed and examined.
