PROCESS FOR PRODUCING A HIGH TEMPERATURE CERAMIC/METAL SEAL - ARCHITECTURE-MICROSTRUCTURE OF THE COMPOSITION EMPLOYED |
摘要 |
Process for producing a joint between a ceramic part and a part made of metal, with a sealing material consisting, for 100% of its weight, of 10 wt% to 90 wt% of a glass or a glass mixture (G); and 10 wt% to 90 wt% of at least one ceramic (C), said process comprising the following successive steps: either - a step (a) of preparing a powder blend (B) consisting, of a glass powder (G) and a ceramic powder (C); - a step (b) of pressing a preform, obtained from the powder blend (B); - a step (c) of densifying the preform; - a step (d) of positioning the elements of the ceramic joint that are complementary to the preform; and - a step (e) of positional heat treatment of the seal prepared in step (d), or - a step (b) of pressing a preform of a powder of at least one ceramic (C); - a step (c) of partially densifying the preform; - a step (d) of positioning the elements of the ceramic/metal joint that are complementary to the preform; and - a step (e') of heat treating the preform so as to cause the glass to infiltrate into the porosity of said preform. Sealing material employed and ceramic/metal joint assembly that includes said sealing material. |
