CA 2447806

The present invention relates to improved matallurgical powder compositions that incorporate solid lubricants, methods for preparing and using the same, and methods of making compacted parts. Ejection properties, such as stripping pressure and sliding pressure, of compated parts can be improved by using the solid lubricants.The solid lubricants contain functionalized polyalkylene lubricants have the formula: R1 Q- R2 where Q is a linear or branched, polyalkylene containing from about 10 to about 200 carbon atoms, and R1 and R2 are each independently a hydroxyl group, a carboxylic acid group or a metal salt thereof, an amine group, a mono- or di- C1 to C25 alkyl substituted amine group, or an alkylene oxide group having the formula: -[(CH2)qO]nH where q is from about 1 to about 7, n is from about 1 to about 100.

L'invention concerne des compositions en poudre métallurgiques améliorées comprenant des lubrifiants solides, des procédés de préparation et d'utilisation de ces compositions, ainsi que des procédés de fabrication d'éléments comprimés. Des propriétés d'éjection telles que pression d'arrachage et pression de glissement des éléments comprimés peuvent être améliorées grâce à l'utilisation de lubrifiants solides. Ces lubrifiants solides contiennent des lubrifiants polyalcoylène fonctionnalisés de formule R¿1? Q R¿2?, dans laquelle Q représente un polyalcoylène linéaire ou ramifié contenant environ 10 à environ 200 atomes de carbone, et R¿1? et R¿2 ?représentent chacun indépendamment un groupe hydroxyle, un groupe acide carboxylique ou un sel métallique de celui-ci, un groupe amine, un groupe amine à substitution mono- ou di- alkyle C¿1? à C¿25?, ou un groupe oxyde alcoylène de formule [(CH¿2?)¿q?O]¿n?H, dans laquelle q vaut environ 1 à environ 7 et n vaut environ 1 à environ 100.
