CONSIDERATION ABOUT CAVITATIONAL DESTRUCTION OF RUSTLESS AUSTENITE-FERRITE STEEL WITH 19,75 Cr AND 3,4 Ni

摘要

This paper presents the experimental results of cavitational test of rustless steel-austenite ferrite structure. In the same time, there is studied the destruction mechanism and changes. There are made by cavitational erosion proceeded from microphotos achieved on different attack time. The cavitational erosion tests are achieved on vibrating magnetostrictive instrument with nickel pipe in the Timisoara Hydraulic Machinery Laboratory.
