Dans la composition, Sn et P sont présents en tant qu'alliages de SnP sous forme de poudre ou bien Sn est présent sous forme d'une poudre métallique et P est présent sous forme d'une poudre ferrophosphoreuse; la teneur en Sn, sur la base de la totalité de la composition en poudre à base de fer, est d'au moins de 4,5 % en poids et les particules individuelles contenant Sn et P sont présentes en tant que particules sensiblement séparées des particules de la poudre de fer non-alliée. Enfin, Sn et P peuvent également être présents en tant qu'alliage de SnP sous forme de poudre et Sn peut également être présent en tant que poudre métallique. Ladite composition peut éventuellement contenir également P en tant que poudre ferrophosphoreuse.

    摘要: On décrit une poudre à base de fer permettant de produire, par compactage et frittage de poudres, des éléments caractérisés par une excellente résistance et une très faible variation dimensionnelle. La poudre contient, en plus du fer, de 0,5 à 4,5 % en poids de Ni, de 0,65 à 2,25 % en poids de Mo et de 0,35 à 0,65 % en poids de C, ainsi qu'éventuellement un lubrifiant et des impuretés. La variation dimensionnelle maximale est de 0,07 % pour une masse volumique minimale de 6,7 % g/cm3.

    摘要: The machinability of a sintered body produced by sintering from a pressed iron powder mixture can be increased substantially by utilising an iron powder mixture in which manganese sulphide is included in the form of a very fine powder having a particle size of less than 10 µm. The iron powder mixture is prepared by adding the manganese sulphide in the form of the said fine powder having a particle size of less than 10 µm and in an amount such that the finished mixture will contain 0.05-5% by weight of manganese sulphide, preferably 0.3-1.0% by weight of manganese sulphide.

    摘要: For the purpose of lubricating a cavity, particularly an annular cavity in a tool for forging blanks produced by powder metallurgy, a lubricant spray is directed towards a limited portion of the cavity surface and the nozzle is displaced such that impingement area of the spray against the cavity sweeps over the entire surface of the cavity. The impingement surface of the lubricant spray is adapted to cover the radial extension of the annular cavity, the nozzle being displaced along the periphery of the cavity. An apparatus for carrying out the method includes a carrier (10) with a mounting (11) for a swinging arm (12) carrying a spray nozzle (14). The carrier (10) is adapted for being positioned for mounting of the arm coaxial with the axis of the cavity, the arm (12,13) being arranged for positioning the nozzle (14) over a peripheral portion of the cavity. Means (31) are arranged for causing the nozzle (14) to circulate along the periphery of the cavity.
