Abstract (en)

[origin: CA2944238A1] The invention relates to a method for producing a hollow body (23) by cold spraying. According to the invention, a mould core (16) is used for producing the hollow body, said mould core being prepared for the production of the hollow body (23) by cold spraying in a suitable manner by means of an auxiliary layer (21). The auxiliary layer (21) consists 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 (23). The mould core, to which the invention also relates, can therefore advantageously be produced from an inexpensive material such as sand or wood, although said materials are in principle only suitable to a limited extent or not at all for depositing metals by cold spraying. The auxiliary layer (21) can advantageously be applied to the mould core (16) as a foil, or be produced on the mould core (16) by cold-spraying particularly low-melting and/or soft materials.
