  • Centrifugal atomization of iron-based alloys
    Patent number: 10273567
    Abstract: A method for the production of iron-based alloy powders, or particulate materials, through rotating or centrifugal atomization (CA) is disclosed. The invention is suitable for obtaining steel powder, especially tool steel powder, high strength steels and other iron-based alloys of similar properties by means of centrifugal atomization, particularly conducted by means of a rotating element atomization technique. The fine, smooth, low oxygen content and low satellite, or even satellite-free, powder is atomized by a cooled rotating atomization device (e.g. disk, cup, . . . ) with various geometries in an atomization chamber under a preferably non-oxidizing atmosphere.
    Type: Grant
