Process of producing a mechanically alloyed composite powder

摘要

In a process of producing mechanically alloyed composite powder, a mixture consisting of at least one metallic powder and at least one non-metallic powder or of a plurality of metallic powders is ground in a drum mill in which a large amount of energy is introduced into the material being ground. To obtain composite powders having reproducible properties for mechanical technology, the powders are ground in a centrifugal mill which has a cylindrical grinding drum, which rotates about its axis and revolves on an orbit about a stationary axis that is parallel to the axis of the drum. Said revolution is effected at an angular velocity that has a constant ratio to the angular velocity at which the drum rotates about its own axis.
