The Volume Factor in Cavitation Erosion

نویسنده

چکیده

Use of jet cavitation, however, occurs through an exit nozzle whose diameter can be changed, thereby changing volume with changing velocity. The results of such a change is shown to tie cavitation damage more powerfully to volume flow than to velocity. A specific example is in cavitation erosion of a high strength igneous rock which remained virtually undamaged at 70 MPa driving pressure but was substantially eroded where nozzle diameter was increased and the driving pressure reduced to 40 MPa.

Synergistic effect of ultrasonic cavitation erosion and corrosion of WC-CoCr and FeCrSiBMn coatings prepared by HVOF spraying.

The high-velocity oxygen-fuel (HVOF) spraying process was used to fabricate conventional WC-10Co-4Cr coatings and FeCrSiBMn amorphous/nanocrystalline coatings. The synergistic effect of cavitation erosion and corrosion of both coatings was investigated. The results showed that the WC-10Co-4Cr coating had better cavitation erosion-corrosion resistance than the FeCrSiBMn coating in 3.5 wt.% NaCl ...

Microstructural Transformations of a Duplex Steel Weld and their Influence on the Particle and Cavitation Erosion Resistance

Original scientific paper The microstructural transformations which took place during the welding of duplex steel as well as their influence on the resistance to particle erosion wear and cavitation erosion wear were investigated. A sample was cut from a 1.4462 rolled steel plate and heat treated in order to obtain a microstructure which would resemble, as closely as possible, the actual welded...

A New Parameter to Predict Cavitation Erosion

In order to avoid or predict cavitation erosion, it is necessary to know resistance of materials against to cavitation impacts. The cavitation impacts, which are larger than certain threshold level, only affect cavitation erosion of materials. In the present paper, existence of the threshold level was revealed experimentally. The threshold level of material is a new parameter to predict the cav...
