ABSTRACT:
Activation of metallic powders by subjecting the powder to bombardment with electrons, ions, or molecules in an inert or reductive atmosphere. Improved densities result in sintering, as do improved catalytic actions. Simultaneous pulverization of coarse particles or bodies is also achieved where desired. The pretreatment is, in some instances, combined with loading the activated particles directly into a mold, for compaction or sintering, preferably with some additional activation, all done in an integrated system. The corpuscular particle bombardment of powder is advantageously effected by exposing the powder to a glow discharge produced between a pair of electrodes in a rarefied non-oxidizing atmosphere with the pressure of the atmosphere and the distance between the electrodes being such that their product in mm Hg times cm is in a range between 10.sup.-2 and 10.
