Abstract
Vorrichtung zum Beschichten von Substraten mit wenigstens zwei Tiegeln, in denen Materialien verdampft werden, wobei diese Tiegel relativ zu wenigstens einer Verdampferquelle verdrehbar sind, dadurch gekennzeichnet, dass das in den Tiegeln (5 bis 8) zu verdampfende Material durch die Enden von Werkstoff-Stäben gebildet wird, die entlang ihrer Längsachse verschiebbar sind, wobei die Werkstoff-Stäbe in oder an einem Revolvermagazin (11, 12) angeordnet sind.Device for coating substrates with at least two crucibles in which materials are evaporated, these crucibles being rotatable relative to at least one evaporator source, characterized in that the material to be evaporated in the crucibles (5 to 8) passes through the ends of material rods is formed, which are displaceable along its longitudinal axis, wherein the material rods are arranged in or on a revolver magazine (11, 12).
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device according to the preamble of
Zum Beschichten von Substraten sind verschiedene Verfahren bekannt.For coating substrates, various methods are known.
Besondere Probleme treten dann auf, wenn ein Substrat nicht nur mit einer Schicht, sondern mit mehreren Schichten versehen wird. Dies ist beispielsweise bei Turbinenschaufeln der Fall, wenn deren Thermobarriere effizienter gemacht werden soll. Es müssen dann verschiedenartige keramische Schichten in unterschiedlichen Dicken auf den Turbinenschaufeln aufgebracht werden.Particular problems arise when a substrate is not provided with only one layer, but with several layers. This is the case, for example, with turbine blades, if their thermal barrier is to be made more efficient. Different types of ceramic layers of different thicknesses must then be applied to the turbine blades.

Aufgabenstellungtask
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, bei welcher das zu verdampfende Material während des Betriebs nachgeschoben und in einem Maße zur Verfügung gestellt wird, dass ein Dauerbetrieb der Vorrichtung möglich ist.The invention has for its object to provide a device according to the preamble of
Diese Aufgabe wird gemäß den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved according to the features of
Die Erfindung betrifft somit 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. Um einen für einen Dauerbetrieb genügenden Vorrat zu haben, werden die Stäbe in oder an einem Revolvermagazin angeordnet.The invention thus relates to a device for coating substrates with at least two crucibles in which materials are evaporated by means of electron beam guns. Here, the crucible are rotatable relative to at least one evaporator source. The material to be vaporized in the crucibles is formed by the ends of material rods that are advanced along their longitudinal axis. In order to have a supply sufficient for a continuous operation, the rods are arranged in or on a revolver magazine.
Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, dass ein Tiegel oder eine erste Gruppe von Tiegeln für den Verdampfungsvorgang verwendet wird, während ein anderer Tiegel oder eine zweite Gruppe von Tiegeln mit anderem Verdampfungsmaterial in Warteposition steht.The advantage achieved by the invention is in particular that a crucible or a first group of crucibles is used for the evaporation process, while another crucible or a second group of crucibles with other evaporation material is in waiting position.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawings and will be described in more detail below.
