Method of cavitation erosion test
1 Scope
This document specifies the test device, specimen preparation, test conditions, test flow, data processing and test report of cavitation erosion test.
This document is applicable to the cavitation erosion test of materials using vibration, turntable and jet cavitation erosion test devices, and is used to evaluate the cavitation damage and cavitation erosion resistance of metal materials in fluid media. It may serve as a reference to other materials subjected to cavitation erosion caused by liquid impact.
