摘要： Method for vaporizing alloys containing metals having different vapor pressures from elongated vaporizing crucibles which are fed with the alloy to be vaporized in rod form at several points along the length of the crucible. The alloy is vaporized by direct bombardment of the molten bath surface with electron beams periodically deflected according to a pattern for the deposition of the alloy coating material on a plurality of substrates positioned above the vaporizing crucible. The proportional composition of the alloy to be vaporized is regulated differently over the length of the crucible such that the alloy component with the lowest boiling point (or the highest vapor pressure) is in a smaller proportion in the alloy to be vaporized which is fed to the center of the vaporizing crucible than in the alloy fed to the ends of the vaporizing crucible.

摘要： High-purity metal powder is made by the electron beam melting of a starting material in rod form in a vacuum wherein the molten metal is momentarily caught on a spinning plate rotating at high speed and flung therefrom and thereafter solidified by cooling. The metal on the spinning plate is bombarded with an electron beam that is so focused and periodically deflected that its focal spot is many times smaller than the diameter of the spinning plate. The beam deflection between the rotational center of the spinning plate and its marginal area is performed such that the spinning plate is scanned in a zone that extends radially of the axis of rotation of the spinning plate and is small in relation to its diameter. Cooling of the metal particles to the point of solidification is accomplished by radiation loss.
