Cavitation Fatigue. Embolism and Refilling Cycles Can Weaken the Cavitation Resistance of Xylem [PDF]

Plant Physiology, 2001
Abstract Although cavitation and refilling cycles could be common in plants, it is unknown whether these cycles weaken the cavitation resistance of xylem. Stem or petiole segments were tested for cavitation resistance before and after a controlled cavitation-refilling cycle. Cavitation was induced by centrifugation, air drying of shoots,

On the Cavitation Erosion Resistance of Coatings

Journal of the Society of Materials Science, Japan, 1965
The propellers of ships have often been observed as damaged as a result of cavitation erosion. Although several investigations have been made on the problem of cavitation erosion of coatings by way of prevention against damage of propellers, the cavitation tests have been conducted under different test conditions with different test methods.
