Patent

CA 2472378

A method of joining metal and ceramic parts, wherein an alumina forming metal part and a ceramic part are provided. A braze material in placed between the alumina forming metal part and the ceramic part, and the combination is then heated in an oxidizing atmosphere, preferably in air at a temperature of between 500 ~C and 1300 ~C. The alumina forming metal parts are selected from the group consisting of high temperature stainless steels, such as Durafoil (alpha-4), Fecralloy, Alumina-coated 430 stainless steel and Crofer-22APU, and high temperature superalloys such as Haynes 214, Nicrofer 6025, and Ducraloy. The braze material is selected as a metal oxide-noble metal mixture, preferably AG-CuO, Ag-V2O5, and Pt-Nb2O5, and more preferably between 30.65 to 100 mole% Ag in CuO.

Procédé de collage de parties céramiques et métalliques qui utilise une partie métallique de formation d'alumine et une partie céramique. Une matière de brasage est placée entre la partie métallique de formation d'alumine et la partie céramique; leur combinaison est ensuite chauffée dans une atmosphère oxydante, de préférence dans l'air, à une température entre 500 ·C et 1300 ·C. Les parties de formation d'alumine sont sélectionnées dans le groupe constitué d'aciers inoxydables haute température tels que Durafoil (alpha-4), Fecralloy, acier inoxydable 430 à revêtement en alumine et Crofer-22APU et de superalliages haute température tels que Haynes 214, Nicrofer 6025 et Ducraloy. La matière de brasage est sélectionnée sous la forme d'un mélange de métaux nobles - d'oxydes de métaux, de préférence AG-CuO, Ag-V<sb>2</sb>O<sb>5</sb> et Pt-Nb<sb>2</sb>O<sb>5</sb> et si possible entre 30,65 et 100 mole % Ag dans CuO.
