ABSTRACT:
An apparatus is disclosed for manufacturing splat foils by disintegration and rapid solidification of metallic melts. The apparatus has a self-consuming electrode disposed above a rotatable counter electrode. Attached to the counter-electrode is a conical plate which is cooled by a fluid circulating through its interior. The application of electrical energy to the electrodes causes the self-consuming electrode to melt and drop melt droplets onto the rotating counter-electrode. Centrifugal force causes the melt droplets to fly off the counter-electrode and contact the conical plate at which point they are rapidly cooled to form thin foils. A housing surrounds the electrodes and conical plate to collect the cooled foils and to permit the apparatus to operate in an inert atmosphere, if desired.
