Abstract
A rotary electrode apparatus for producing metal powders including a chamber for maintaining a controlled atmosphere. A first electrode is mounted in the chamber and a second consumable disc electrode is mounted in the chamber confronting the first electrode. An electric arc is struck between the first electrode and a circumferential portion of the disc electrode in order to melt the circumferential portion. The disc electrode is rotated at sufficient speed to enable melting of the circumferential portion of the disc and spinning off of melted portions of the disk.
