Abstract

L'invention concerne le revêtement des métaux. Elle se rapporte à des opérations de métallisation par revêtement par diffusion sur des parties choisies de pièces seulement, les parties qui ne doivent pas être revêtues étant protégées par des compositions formant des caches qui, lors du traitement de diffusion, constituent une gaine protectrice qui peut être retirée ultérieurement. Les caches ne contaminent pas la matière utilisée pour le revêtement par diffusion. Application à la réalisation d'ailettes de compresseurs pour réacteurs.The invention relates to the coating of metals. It relates to metallization operations by diffusion coating on selected parts of parts only, the parts which are not to be coated being protected by compositions forming caches which, during the diffusion treatment, constitute a protective sheath which can be withdrawn later. The covers do not contaminate the material used for the diffusion coating. Application to the production of compressor fins for reactors.
