Abstract: Disclosed are a method and a device for filling material separations on the surface. In methods known in prior art, which are used for filling material separations, the substrate is often influenced in a negative manner by high processing temperatures and dissimilar additives. The inventive method overcomes said disadvantage, taking place at low temperatures and allowing the material separation to be completely filled without using dissimilar substances.

Abstract: Inner coatings according to the prior art often do not produce a uniform coating. The method according to the invention for the coating of a component with a cavity is characterized in that a coating material is mixed with a carrier material and introduced into the cavity, the carrier material decomposing at the evaporating temperature of the coating material, or has already decomposed, and the coating material being deposited from the gas phase on the component.

Abstract: The invention relates to a method for the nondestructive testing of a component, in which corrosion regions close to the surface, composed of oxidized carbides or sulfided base material close to the surface, are determined by means of an eddy current measurement. This allows the blades or vanes to be ground down and/or separated out in particular prior to a complex process of cleaning and coating the gas turbine blade or vane.

Abstract: A method and device for layer thickness determination allows for the layer thickness to be determined in situ during the coating process. This is achieved using a sensor which has an electrical property which, as a result of the coating process, changes in a manner which is representative of the layer thickness which has been reached. As such, this property can be measured.

Abstract: The prior art involves removing surface regions of a metallic component by means of electrochemical processes. The electrochemical process is accelerated by the use of a current pulse generator (16).

Abstract: Coatings that are applied to a component have to be removed again from certain areas using costly methods, because coating was not required in those areas. The subsequent removal of this layer can impair the component, for example in terms of its geometry. The inventive method for coating a component uses a mask, which consists at least partially of a ceramic powder and can therefore easily be removed after the component has been coated.

Abstract: Masking layers for components according to the prior art react with the base material of the component and/or are difficult to remove again. The component according to the invention has a masking layer which can very easily be removed following coating of the components, since on the one hand the bonding between the masking layer and the base material of the component is poor, or the masking layer can easily be removed through penetration of a liquid.

Abstract: A process is intended to allow simple and particularly reliable electrolyte generation and conditioning from metal-containing used electrolytes and/or used process solutions and/or pulverulent metal wastes. For this purpose, waste products (a, b) containing metal ions from metal surface treatment processes are to be treated by producing and/or using a metal ion mixed solution (m), replacing anions contained in the metal ion mixed solution (m) with anions selected for an intended use selected and selectively removing metal ions which are categorized as unsuitable for the intended use selected from the metal ion mixed solution (v) prepared in this way.

Abstract: This invention relates to an electrolytic process for the deposition of a graduated layer on a substrate. The process includes depositing a composite material having a first constituent and a second constituent forming a graduated layer on a substrate, introducing the substrate into an electrolyte for a period of time, varying the fist and second constituents of the electrolyte during the period of time to achieve the graduated layer, and using a current/voltage pulse for the electrolytic deposition such that an optimized deposition of the constituents occurs.

Abstract: A metallic layer is cooled below room temperature, leading to an embrittlement. Subsequently, the metallic layer is stripped by performing a blasting process having a high efficiency because of the brittleness. Additionally, the substrate is prevented from being damaged by using a comparatively low blasting energy.

Abstract: The invention relates to a method and device for polishing the surface of a gas turbine blade. According to the invention, a metallic anticorrosive layer is polished by using a stream of dry ice whereby preventing the surface from becoming contaminated and obtaining cost advantages.

Abstract: The invention relates to a method for removing an area of a layer of a component consisting of metal or a metal compound. According to prior art, corrosion products of a component are removed in a first step by applying a molten mass or by heating in a voluminous powder bed. This requires high temperatures or a large amount of space. The inventive method for removing corrosion products of a component is characterized in that a cleaning agent is applied locally, which removes the corrosion products by means of a gaseous reaction product.

Abstract: The invention relates to a method for carrying out nondestructive testing of a gas turbine blade during which corrosion areas, which are located near the surface and which consist of oxidized carbides or of base material that is sulfidized near the surface, are determined by means of an eddy current measurement. As a result, the blades can be ground or sorted, in particular, before subjecting the gas turbine to a complicated cleaning and coating process.
