  • Manufacture Of Metal Powder And Suspensions Thereof (AREA)

Abstract

PURPOSE: To produce titled powder of desired good quality causing no change in composition by irradiating vacuum plasma to the raw material in a vacuum chamber by the use of a hollow hot cathode to allow said material to melt and rotationally scattering the molten metal.
CONSTITUTION: A plasma source gas such as gaseous Ar is introduced into a vacuum chamber 1 which is kept under about a middle degree of vacuum. After this, high frequency is applied between a hollow hot cathode 2 and an ingot 9, so that vacuum plasma is produced. The instant when the plasma is produced, a high frequency electric power source 7 is switched to a plasma electric power source 8 (DC), to maintain the irradiation of the vacuum plasma to the ingot 9. At the same instant when the top part of the ingot 9 begins to melt by the irradiation of the vacuum plasma, the ingot 9 is rotated at a suitable number of revolutions. The melt is scattered by the centrifugal force of this revolution, and is collided against the inside surface of a water-cooled collector 4, by which it is quickly solidified to required metallic powder. Since this method is not practised in a high vacuum, no composition changes occur in the resultant alloy powder.
