摘要：

Cavitation erosion represents an actual problem in machines, whose components such as propellers, blades of hydraulic pumps and turbines, are exposed to high-speed flow of liquid. Reasearch exhibited that hydraulic machinery parts during cavitation are exposed to mechanical action, electrochemical corrosion as well as local temperature increase. Therefore, high ductility, hardness, tensile strenght, dynamic strenght and corrosion resistance represent main properties in the choice of materials for producting hydraulic machinery parts. These properties depend on chemical composition and microstructure of materials. In this paper cavitation phenomenon was analyzed from laboratory investigation stand point by use modified ultrasonically induced cavitation test method.
