Abstract: A small solder rod with a stop-off at the end in order to prevent the solder from dripping from an opening is provided. A process for applying solder to a hole in a substrate, wherein the solder is used in the form of a wire or a small rod is also provided.

Abstract: Process for preparing turbine blades or vanes for a subsequent treatment, for example the application of a coating and/or a material-removing operation, wherein the turbine blade or vane has an airfoil, which is delimited at at least one end by an endplate with peripheral surfaces, wherein at least one of the peripheral surfaces is at least partially covered prior to the treatment of the turbine blade or vane. In the process a covering strip is fitted onto at least one peripheral surface to form a plug connection.

Abstract: The invention relates to a method for production of turbine components having at least one flow body, which has cooling air outlet openings arranged in the area of its trailing edge with the flow body, for example a blade section, being provided with an in particular ceramic coating by spraying coating. According to the invention, before the coating is applied, the cooling air outlet openings are completely covered by a covering strip which is composed of a material which is resistant to the coating process.

Abstract: A method of Fluoride Ion Cleaning (FIC) of a component is provided. A FIC installation includes a reaction chamber and a reactive gas or a reactive gas mixture. A pressure of the reactive gas or the reactive gas mixture in the reaction chamber is set at least occasionally above atmospheric pressure, wherein the pressure in the reaction chamber is periodically lowered and raised.

Abstract: The invention relates to a method of preparing turbine blades for spray coating their blade region that is subjected to the medium flowing through during operation in a spray coating apparatus, in which the turbine blade is inserted with its blade root into a cavity of a mounting in such a way that it protrudes with the blade region that adjoins the blade root from an opening of the cavity to form a gap between the rim of the opening and the turbine blade, and in which the gap is bridged by a shielding fixed on the mounting, which is characterized in that a shielding layer of a plastic which is resistant during the spray coating is used for the shielding, the shielding layer being arranged in such a way that it reaches up to the boundary between the blade root and the blade region.

Abstract: A holder for a component providing spray protection is provided. The insertion of a rod in the side face of the component, the side face is arranged within a housing of the holder, has the additional effect of providing spray protection. The rod rests on an inner face of the holder in one aspect.

Abstract: A method is provided for coating a component with a multilayer ceramic coating in which the individual layers of the ceramic coating are applied covering one another on the component, and in which ceramic particles are supplied to a coating burner, melted partly or completely by the coating burner, and deposited on the component. The ceramic particles have a particle size, which increases from layer to layer, and are supplied to the coating burner. Furthermore, a multilayer ceramic coating and a component which has with a multilayer ceramic coating are provided.

Abstract: A method for optimizing the coating of a component using a coupon by introducing the coupon into a depression of the component, in which the geometry of the component is not altered as compared to a component without a coupon, is provided. A component having a depression into which a coupon is fastened is also provided.

Abstract: Conventional welding methods have the disadvantage of producing worse welded joints at the beginning of the process than in the later course of the method. The method in question uses an initializing plate on which the welding process is begun and then once a consistent quality can be achieved for the welded joint continues onto the points for repair.

Abstract: The invention relates to a coating system, especially a low pressure plasma coating system, with at least one treatment chamber and a coating tool, especially a plasma spraying device, wherein at least one pump is provided for evacuation of the treatment chamber, which treatment chamber is formed to be temperature controllable. In addition there is a coating method for low pressure plasma coating with a temperature controlled and evacuated treatment chamber, in which a workpiece is coated by means of at least one coating tool. For acceleration of the coating process, especially the evacuating of the treatment chamber, it is proposed that at least the walls of the treatment chamber and/or the inside of the treatment chamber are temperature controlled at a temperature between 45° C. and 75° C.

Abstract: The invention relates to a method of preparing turbine blades for spray coating their blade region that is subjected to the medium flowing through during operation in a spray coating apparatus, in which the turbine blade is inserted with its blade root into a cavity of a mounting in such a way that it protrudes with the blade region that adjoins the blade root from an opening of the cavity to form a gap between the rim of the opening and the turbine blade, and in which the gap is bridged by a shielding fixed on the mounting, which is characterized in that a shielding layer of a plastic which is resistant during the spray coating is used for the shielding, the shielding layer being arranged in such a way that it reaches up to the boundary between the blade root and the blade region.

Abstract: In internal coating processes there is often the problem that an outer surface of the component to be coated is also coated. The device according to the invention consists in the fact that the outer surface is protected by a robust outer envelope and a filling material between the component to be coated and the outer envelope.
