A. Abouel-Kasem, Auteur ; B. Saleh, Auteur ; S. M. Ahmed, Auteur |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 furthe[...]
