Cavitation erosion of aluminas
Ceramics International, 1999Abstract Various aluminas were eroded in distilled water at 18°C using an ultrasonic facility operating at 20 kHz and with a peak-to-peak amplitude of 50 μm. The progress of erosion was measured by weight loss and the eroded surface was examined using a scanning electron microscope.

Abstract The cavitation in a mechanical heart valve (MHV) is a serious concern. In most of the investigations of the MHV cavitation in vitro, the tap water, the distilled water, or the glycerin are used as the test liquids, instead of the real blood. Therefore, the effects of the liquid properties on the cavitation can not be well revealed.

Metallurgical and Materials Transactions A, 1999
Vibratory cavitation erosion tests were carried out on as-cast NiAl intermetallic compounds containing 46.5 to 62.1 at pct Ni. The erosion rate decreased with increasing nickel content by over two orders of magnitude, from a high of 16.4 to 0.11 mg·h−1. These low erosion rates exhibited by the nickel-rich alloys containing 58 and 62.1 at.

The Mechanism of Cavitation Erosion
Journal of Applied Mechanics, 1942Abstract After pointing out the interrelation between corrosion resistance, caustic embrittlement, fatigue, creep, and other phenomena of metals, the author cites the results of experiments on glass and quartz rods, subjected to high liquid pressures, as indicative of the action which probably occurs in cavitation erosion. To demonstrate

<div class="htmlview paragraph">Cavitation-erosion is a peculiar form of corrosion or pitting which occurs on the water side of Diesel engine cylinder liners, on hydraulic turbines, on centrifugal pumps and on high speed ship propellers causing extensive and costly damage. As a result it has been the subject of numerous investigations.

The erosive activity of a sound field can be enhanced by the addition to the liquid of finely disperse abrasive particles commensurate in size with the effective range of the shock wave created by the implosion of a cavitation bubble. In this case, besides the purely cavitation destruction of solids, the surface of the latter is further acted upon in ...

Hydroturbine Cavitation Erosion
Journal of Energy Engineering, 1992This paper is based on an analysis of turbine cavitation data obtained from 729 turbines installed in the United States since 1950 and 19 selected Canadian turbines. An equation has been developed to express the anticipated rate of cavitation within 75% and 95% confidence limits.
