Abstract

a. Pièce autolubrifiante de machines réalisée à l'aide de poudres métalliques et procédé pour la fabrication de telles pièces. b. Pièce caractérisée en ce qu'elle est en poudre d'acier inoxydable, frittée, avec une densité notablement inférieure à la densité théorique pour que la porosité reste essentiellement interconnectée (ouverte) et une partie de la porosité, en commençant à la surface extérieure de la pièce en direction de l'intérieur, est imprégnée avec un métal choisi dans le groupe formé par le bismuth et un alliage riche en bismuth à faible coefficient de frottement. c. L'invention concerne la fabrication de pièces autolubrifiantes.
