Definitions

  • the invention relates to a method for producing a mechanically alloyed composite powder by grinding of at least one metal powder with at least one non-metallic powder or metallic powder whose components are imperfectly in the liquid state or not at all soluble in each other, in a T drum mill with high energy input in the regrind, if necessary under control of the atmospheric and / or temperature conditions.
  • the method of mechanical alloying enables the production of composite powders, the fine dispersion of a metallic or nonmetallic particles of low T eilchenabstand in a metallic matrix exist.
  • the method is used for the production of such alloys, the components of which are not sufficiently soluble in one another in the molten state and / or which are subject to undesirable oozing out during solidification.
  • metallic powder and one or more ingredients such as refractory oxide powder or other metal powder in a drum mill T with high energy input ground.
  • the powder particles are rolled out and / or crushed into thin foils by the grinding media and at the same time the thin foils are welded together again and again.
  • the solution of this problem is the use of a centrifugal mill with a cylindrical grinding drum, which rotates about its own axis and rehkir simultaneously on a rotation circle with a constant D about a fixed and the axis of the grinding drum parallel R OTA tion axis is rotated and a drive mechanism for the Rotation of the grinding drum around the drum axis and for rotation on the rotation circle of the axis of the grinding drum is provided.
  • the center of rotation lies within the cross section of the grinding vessel.
  • the M ahlgefäß itself no rotational movement leads around its own axis.
  • centrifugal mill known from DE-OS 26 31 826, which has no critical speed, uses up to 30 times the acceleration due to gravity for grinding, in contrast to the mills described above in relation to the prior art. This leads to a much higher E nerve-gie Notice in the mill and therefore a substantially smaller construction.
  • the centrifugal has been previously used for grinding mineral R ohstof- fen and other products to high fineness and specific surface areas due to the high efficiency and for F einmahlung of coal in K ohle / water or K ohle / oil suspensions.
  • the very good mixing effect due to the high effective centrifugal forces has a positive effect here.
  • D is missing a complicated sprockets and pinions, wear is correspondingly lower.
  • the degree of filling is expediently 30 to 90% with a throughput of 0.01 to 1.5 t / h.
  • the high plastic deformation is essential for the mechanically alloyed composite powders produced in the Z centrifugal mill of predominant importance, which creates the high hardness of the powder particles.
  • the composite powders can be compacted by extrusion and, if necessary, then heat-treated.
