Abstract
The direct liquid phase bonding of ceramics to metals or other ceramics in an inert atmosphere without prior metallization wherein a nickel-plated aluminum-silicon brazing alloy or aluminum or aluminum alloy filler material between the ceramic and metal layers provides a joint of high strength at a low bonding temperature without affecting the ceramic microstructure or the mechanical properties of the materials. This technique is also useful for fabricating composite laminates.
