Titel
(EN) Method For Producing A Hollow Body By Cold Spraying And Mould Core Suitable For Carrying Out Said Method
Zusammenfassung
(EN)

A method is disclosed for producing a hollow body by cold spraying. A mold core is used for producing the hollow body, the mold core being prepared for the production of the hollow body by cold spraying in a suitable manner by means of an auxiliary layer. The auxiliary layer may include or consist of a metallic material and therefore forms a suitable surface to which the particles processed by cold spraying remain adhered to form the hollow body. The mold core can therefore be produced from an inexpensive material such as sand or wood, although said materials are in principle have limited suitability for depositing metals by cold spraying. The auxiliary layer can be applied to the mold core as a foil, or be produced on the mold core by cold-spraying low-melting and/or soft materials, for example.
