Apparatus for coating turbine blades with ceramic has crucibles which can be rotated with respect to electron beam guns, bars of material to be vaporized being positioned with their upper ends in crucibles and exposed to beams

Apparatus for coating substrates has at least two crucibles (5 - 8) which can be rotated with respect to electron beam guns. Bars of material to be vaporized are positioned so that their upper ends are in the crucibles and are exposed to the beams. The beams are moved upwards as they are vaporized....

Beschreibung
Zusammenfassung:	Apparatus for coating substrates has at least two crucibles (5 - 8) which can be rotated with respect to electron beam guns. Bars of material to be vaporized are positioned so that their upper ends are in the crucibles and are exposed to the beams. The beams are moved upwards as they are vaporized. Die Erfindung betrifft eine Vorrichtung zum Beschichten von Substraten mit wenigstens zwei Tiegeln, in der mittels Elektronenstrahlkanonen Materialien verdampft werden. Hierbei sind die Tiegel relativ zu wenigstens einer Verdampferquelle verdrehbar. Das in den Tiegeln zu verdampfende Material wird durch die Enden von Werkstoff-Stäben gebildet, die entlang ihrer Längsachse nachgeschoben werden.
