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.

Journal of Hydrodynamics, 2017
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.

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.

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.

Cavitation Erosion in Hydroturbines
Journal of Hydraulic Engineering, 1989This paper is based on a field survey of the operational and design characteristics of 729 hydroturbines installed since 1950 having either a capacity in excess of 20 MW or a discharge diameter greater than 3 m. This data base includes 67% of the total U.S. hydropower capacity (40,000 MW).
