Zusammenfassung:The process serves for coating poorly accessible wall surfaces, entirely or partly enclosing cavities, of metal articles with thermoplastic powder. To make such poorly accessible wall surfaces accessible to coating with thermoplastic powder, the article to be coated is brought at least to the melting point of the plastic powder and the plastic powder is injected as a cloud into the cavity and deposited on the hot application surface.
