Titre : Improved wear resistance of dendrite composite eutectic Fe-B alloy Type de document : texte imprimé Auteurs : Licai Fu, Auteur ; Jun Yang, Auteur ; Qinling Bi, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Dendrites  Eutectic  alloys  Friction  Oxidation  Wear  resistance Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The dry-sliding tribological properties of the dendrite composite eutectic Fe-B alloys (Fe94.3B5.7, Fe75B25 Fe67B33) were studied comparatively with various sliding speeds. The friction coefficient of the Fe-B alloy changes slightly with the boron content. The wear rate of the Fe94.3B5.7 alloy with about 30 vol. % dendrite t-Fe2B is only one third of Fe75B25 alloy with 15 vol. % dendrite and Fe67B33 alloy with 90 vol. % dendrite in the high sliding speed. First, a hard t-Fe2B phase reduced the wear of the Fe-B alloy directly. Second, the compactly oxide layers resulting from oxidation of the alpha-Fe on the worn surfaces also decreases the wear rate of Fe-B alloys. On the whole, the wear rate of the Fe94.3B5.7 is lower than Fe67B33 and Fe75B25.
