  • Process for joining metallic and ceramic materials
    Patent number: 4927475
    Abstract: A process for joining components having ceramic and metallic joining surfaces provides a permanent and complete joint with ceramic surfaces despite metal-oxide layers on the metal or metal-alloy joining surfaces. A glass coating is applied to the ceramic joining surface before joining. The glass contains at least 5 to 20% by weight of Na.sub.2 O, 30 to 60% by weight of B.sub.2 O.sub.3 and 20 to 60% by weight of SiO.sub.2. The surfaces of the components to be joined are then permanently joined to each other at a specified temperature and a specified pressure.
