...Dayun Yan; Jiadao Wang In summary, the ring area around the cavitation erosion pit is determined by the ions in water as well as the acoustic streaming induced by the oscillation of the horn. The ions determine the submicron structure and the chemical composition of the nascent ring area...

... cavitation erosion in laboratory tests. The vibratory facility, as reported in Ref. [ 3 ] is the most commonly used of these devices because it facilitates the conduction of accelerated tests, allowing a large quantity of data to be collected over a relatively short period using a wide variety of test...

...A. Abouel-Kasem; F. A. Alturki; S. M. Ahmed In the present work, the topographical images of cavitation erosion surfaces at water and oil-in-water (o/w) emulsions were quantified using fractal analysis. The oil-in-water emulsion concentrations were 2, 5 and 10 wt. %, which are in the popular range...

...B. Saleh; A. Abouel-Kasem; A. Ezz El-Deen; S. M. Ahmed The effect of temperature on the wear particles produced by vibratory cavitation erosion tests on Al-99.92 in distilled water was analyzed. Scanning electron microscope images of wear particles were obtained, forming a database for further...

...A. Abouel-Kasem; A. Ezz El-Deen; K. M. Emara; S. M. Ahmed Cavitation erosion pits and their effects on erosion progression were investigated in detail for SUS 304 stainless steel, α + β brass (60/40), and pure aluminum (Al-99.999 and Al-99.92) by means of vibratory erosion. Two kinds of erosion...

...A. Abouel-Kasem; B. Saleh; S. M. Ahmed Wear particles produced by vibratory cavitation erosion tests on 1017 carbon steels in water and oil-in-water (o∕w) emulsions were analyzed. Scanning electron microscope (SEM) images of wear particles were acquired, forming a database for further analysis...

...A. Abouel-Kasem; S. M. Ahmed The mechanism of cavitation erosion is investigated in detail through observations of the removed particles from pure aluminum (Al-99.999). The particles removed during the incubation stage have distinctive characteristics compared to those removed in the subsequent...
