Abrégé
(EN)
A method of forming a metallic wetting layer on the surface of a metal component is provided, including the steps of placing the component into a chemical vapor deposition furnace, placing a metal-containing salt in the furnace, and heating the component and the metal-containing salt in the furnace to cause the metal from the metal-containing salt to deposit in a coating on the surface of the component forming a metallic wetting layer that improves the metallic bond of a subsequently applied brazing material. The process can be practiced with the addition of a cleaning reagent to both clean and coat in one operation.
(FR)
La présente invention concerne un procédé de formation d'une couche de mouillage métallique sur la surface d'un élément métallique, comprenant les étapes consistant à placer l'élément dans un four de dépôt chimique en phase vapeur, à placer un sel contenant du métal dans le four, et à chauffer l'élément et le sel contenant du métal dans le four pour amener le métal provenant du sel contenant du métal à se déposer dans un revêtement sur la surface de l'élément formant une couche de mouillage métallique améliorant la liaison métallique d'un matériau de brasage appliqué par la suite. Le processus peut être mis en pratique avec l'ajout d'un réactif nettoyant pour effectuer un nettoyage et un revêtement au cours d'une seule opération.
