Abstract: A device for vaporizing coating material is disposed in a vacuum chamber as part of a deposition apparatus; the coating material being arranged in a crucible for vaporization purposes. The vaporizing device has an evaporation chamber that is connected, via a vacuum valve, to a loading chamber which can be evacuated while an evaporator is connected to the evaporation chamber at a vapor discharge end, i.e., the end facing the vacuum chamber, via a first vapor stop valve.

Abstract: A thermal vacuum deposition device and method in which a band-shaped substrate is continuously conveyed in a vaporization channel that is charged with a vaporous coating material is characterized in that the vaporization channel is sealed by inserting at least one positionally adjustable hollow element into an outer space of the vaporization channel and an inner space of the vaporization channel when a minimum conveying speed is not attained or when the substrate is at a standstill such that the substrate is located in the inner space.

Abstract: A coating method is provided for thermally vacuum-depositing a continuously conveyed substrate that moves within a deposition channel by vaporizing solid or liquid coating materials and vapor-depositing the vaporized coating material onto the substrate in a deposition device. In order to create a coating conveyed substrate, in which accessibility to the vaporization device is improved while the processes taking place in the deposition chamber and the vaporization device can be controlled independently of each other, at least one evaporation device is located outside the deposition chamber and delivery of steam between the evaporator and the deposition channel is regulated.

Abstract: A valve is used for vapor-tightly disconnecting two interconnected process units. The valve comprises a continuous duct which connects two vacuum evaporators that are individually provided with an outer vapor-proof jacket, and a blocking mechanism mounted in the duct. In order to allow the two interconnected vacuum evacuators to be disconnected in a vapor-proof manner such that the functional reliability is improved, a vapor-impinged surface of the valve duct is provided with a vapor condensation-repellent zone which is connected in a thermally conducting manner to a heating apparatus that envelopes the valve.

Abstract: The invention is an electron-beam vaporization installation for coating structural components made of extreme-heat-resistant alloys (super alloys), especially turbine blades, with so-called thermal barrier coatings. The invention divides the continuous process principle for this coating task with extreme thermal stress for the substrata. The invention divides the thermally high stressed chambers by a partition with a slot. As a result of this the heating chamber and the coating chamber are thermally decoupled from the room for the transport system of the substrata carriage. A further characteristic of the invention is that the carriage for the transport of the substrata through the installation is cooled. For this purpose at the specific work positions the cooling system of the carriage is coupled with the exterior cooling circuits by a leakproof coupling system. The movement of the substrata is done hydraulically and is coupled with the exterior hydraulic circuits in a similar manner as the cooling system.

Abstract: The invention which relates to a device for the generating of electron beams with a vacuum chamber, in which a massive cathode (10) is arranged with a wire cathode (14) arranged above and a aperture anode (17) below the massive cathode (10) and whom below the aperture anode (17) focusing and/or deflecting magnet arrangements are provided which direct an electron beam (23) emitted by the massive cathode (10) and accelerated by the aperture anode (17) to a processing location (22), has the basic task to make the power of such devices variable over a large range using simple mechanical means. According to the invention the task is solved by arranging the aperture anode (17) rigidly and the massive cathode (10) and the wire cathode (14) axially movable within the vacuum chamber (1). For the movements of the massive cathode (10) and the wire cathode (14) contact means are provided which follow their movements and lead to the outside of the vacuum chamber (1).
