FLEXIBLE UNION STAINLESS BETWEEN A METAL SUBSTRATE AND A CERAMIC SUBSTRATE, PROCEDURE FOR CONDUCTING SUCH UNION, APPLICATION OF THE PROCEDURE TO THE SEALING OF HIGH-TEMPERATURE ELECTROLYERS AND FUEL BATTERIES.

摘要

Device comprising a metal substrate (3) and a ceramic substrate (2) comprising a groove (20) against plucking, separated from each other by a flexible seal (5), in which the flexible seal (5) It comprises: - a metal element (30) comprising one end (300) attached to the metal substrate and another end (301) housed in the groove of the ceramic substrate, the metal element being elastically deformable at the same time in the groove in a radial direction (R) to the latter and in the separation space between the metallic substrate and the ceramic substrate according to the direction of separation (X), - a mass (50) forming a joint, of thermal expansion coefficient greater than that of the ceramic substrate and glued to the end of the metal element housed in the groove against the ejection, adapting the joint with direct contact to a part of the height of the converging side walls (200) of the latter (20).
