Investigation of temperature effects on cavitation erosion behavior based on analysis of erosion particles / B. Saleh in Transactions of the ASME . Journal of tribology, Vol. 132 N° 4 (Octobre 2010) 

Public ISBD [article]  in Transactions of the ASME . Journal of tribology > Vol. 132 N° 4 (Octobre 2010) Titre : Investigation of temperature effects on cavitation erosion behavior based on analysis of erosion particles Type de document : texte imprimé Auteurs : B. Saleh, Auteur ; A. Abouel-Kasem, Auteur ; A. Ezz El-Deen, Auteur Année de publication : 2011 Note générale : Tribology Langues : Anglais (eng) Mots-clés : Aluminium  Fatigue  Particle  size  Scanning  electron  microscopy  Wear  Wear  testing Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : 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 analysis. This study showed that the variation of average particle size with temperature was very much similar to the variation of weight loss with temperature. The average particle size was maximum at 40°C. It was also observed that the average particle size was time dependent. The particle's morphology features revealed that the predominant erosion mechanism was fatigue failure, irrespective of the temperature.

Quantitative analysis of cavitation erosion particle morphology in dilute emulsions / A. Abouel-Kasem in Transactions of the ASME . Journal of tribology, Vol. 130 N° 4 (Octobre 2008) 

Public ISBD [article]  in Transactions of the ASME . Journal of tribology > Vol. 130 N° 4 (Octobre 2008) . - 6 p. Titre : Quantitative analysis of cavitation erosion particle morphology in dilute emulsions Type de document : texte imprimé Auteurs : A. Abouel-Kasem, Auteur ; B. Saleh, Auteur ; S. M. Ahmed, Auteur Année de publication : 2015 Article en page(s) : 6 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Wear  Particulate  matter  Cavitation  erosion  Emulsions  Shapes  Water  Mechanisms  Elongation Résumé : 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. The particle morphology features were first clarified. Next, the size parameters (size, area, and perimeter) and shape factors (elongation and roundness) were determined for each test liquid, using image analysis software. The size parameters of the removed particles were higher in water than in o∕w emulsions. While the shape factors could not significantly discriminate between the particles produced in water and o∕w emulsions. The size distribution was in a wide range for water than that for o∕w emulsions. The cavitation erosion mechanism is fatigue failure for water and o∕w emulsions.
