Beschreibung
Zusammenfassung:	The invention relates to a kit for producing a chromium(VI)-free slip suspension for the diffusion coating of metal surfaces. The kit comprises, as separate components, a powder mixture and a liquid binder mixture, which should be combined to produce the slip suspension. The powder mixture contains a powdered diffusion metal. The binder mixture contains an aqueous solvent and a phosphate binder. Both the powder mixture and the binder mixture are free of chromium(VI) salts. The invention also relates to a method for the diffusion coating of metal surfaces of a component using a kit of this type, and to the use of a kit of this type in different industries. L'invention concerne un kit de production d'une suspension de barbotine exempte de chrome(VI), permettant le revêtement par diffusion de surfaces métalliques. Le kit comprend, sous forme de constituants séparés, un mélange de poudre et un mélange de liant liquide, lesquels doivent être combinés pour produire la suspension de barbotine. Le mélange de poudre contient un métal de diffusion en poudre. Le mélange de liant contient un solvant aqueux et un liant phosphate. Le mélange de poudre et le mélange de liant sont tous les deux exempts de sels de chrome(VI). L'invention concerne également un procédé de revêtement par diffusion des surfaces métalliques d'un élément à l'aide d'un tel kit, et l'utilisation d'un tel kit dans différentes industries.
