Title (EN) METALLURGICAL COMPOSITION OF PARTICULATE MATERIALS, SELF-LUBRICATING SINTERED PRODUCT AND PROCESS FOR OBTAINING SELF-LUBRICATING SINTERED PRODUCTS
(FR) COMPOSITION MÉTALLURGIQUE DE MATÉRIAUX PARTICULAIRES, PRODUIT FRITTÉ AUTOLUBRIFIANT ET PROCÉDÉS PERMETTANT D'OBTENIR DES PRODUITS FRITTÉS AUTOLUBRIFIANTS
Abstract: front page image
(EN)The metallurgical composition comprises a main particulate metallic material, for example iron or nickel, and at least one alloy element for hardening the main metallic material, which form a structural matrix (10); a particulate solid lubricant (20)., such as graphite, hexagonal boron nitride or mixture thereof; and a particulate alloy element which is capable of forming, during the sintering of the composition conformed by compaction or by injection molding, a liquid phase, agglomerating the solid lubricant (20) in discrete particles. The composition may comprise an alloy component to stabilize the alpha-iron matrix phase, during the sintering, in order to prevent the graphite solid lubricant from being solubilized in the iron. The invention further refers to a self-lubricating sintered product, obtained from the composition, and to the process for obtaining said product.
(FR)La composition métallurgique selon l'invention comprend un matériau métallique particulaire principal, du fer ou du nickel par exemple, et au moins un élément en alliage pour durcir le matériau métallique principal, qui forment une matrice structurelle (10); un lubrifiant solide particulaire (20), comme du graphite, du nitrure de bore hexagonal ou un mélange de ceux-ci; et un élément d'alliage particulaire qui est apte à former, durant le frittage de la composition qui est réalisé selon un procédé de compaction ou de moulage par injection, une phase liquide, d'où l'agglomération du lubrifiant solide (20) en particules discrètes. La composition peut comprendre un élément d'alliage pour stabiliser la phase matricielle alpha-fer durant le frittage, afin de prévenir la solubilisation du lubrifiant solide au graphite dans le fer. La présente invention concerne également un produit fritté autolubrifiant obtenu à partir de la composition, ainsi qu'un procédé permettant d'obtenir ledit produit.
