Abstract
The cavitation fracture of AMg6, BrAZh9-4, grade 20 steel, 12Kh18N10T, 20Kh13, and VT1-0 alloys, which are used in hydraulic machines and units, is studied. In tests, the materials are subjected to ultrasonic waves and the sample mass loss and the microhardness are measured. It is shown that new cavitation- resistant materials, which have a sufficient strength and plasticity, should be designed.
