Method for coating substrates loaded with temperature and/or hot media and hot media and/or temperature loaded substrate

摘要

The method for coating hot gas-, hot media- and/or temperature-impinged components with a metallic surface, comprises applying a pure metallic aluminum layer on the metallic surface, and producing an alloy layer between the surface and the metallic layer by interdiffusion. After applying the metallic layer, the component is mounted on its operating location and is engaged in the operation. The alloy layer is produced by the process heat during the operation, and is completely produced after assembling the component during the first operation/operation of the component. The method for coating hot gas-, hot media- and/or temperature-impinged components with a metallic surface, comprises applying a pure metallic aluminum layer on the metallic surface, and producing an alloy layer between the surface and the metallic layer by interdiffusion. After applying the metallic layer, the component is mounted on its operating location and is engaged in the operation. The alloy layer is produced by the process heat during the operation, and is completely produced after assembling the component during the first operation/operation of the component. The metallic layer is applied in a low-temperature metalorganic chemical vapor deposition process under inert atmosphere. An aluminum layer or aluminum-nickel compound layer is produced as the alloy layer. Before applying the metallic layer, an intermediate layer such as a homogenous nickel layer or nickel compound layer is applied as metallic surface of the component. The metallic layer is directly applied on the surface of the component, where the component consists of iron material with high nickel-content. A further layer is applied on an inner surface of the hot media-conducting component. A precursor gas is directly guided into the inner space of the component for inner coating of the component. A layer is applied on an inner and/or outer surface of the hot gas-impinged component. The component is coated in a reactor, where at the same time an outer coating of further component takes place. The component is partially coated in selected structures. An inflow direction of the precursor gas is adjusted to the selected structures of the component. An independent claim is included for a hot gas-, hot media- and/or temperature-impinged component.
