Abstract

Two components, e.g. of ceramic, metal or both, are bonded together by means of an interfacial layer of devitrified sealing glass containing a nucleating agent such as phosphate ions, metallic fluorides, or metals. Preferred glasses are of LiO2 and SiO2 to which either Al2O3, MgO or both may be added, several examples being given. The preferred nucleating agent comprises phosphate anions resulting from the inclusion in the glass of P2O5, but other agents mentioned are metallic fluorides, cadmium sulphoselenide, gold, silver and copper. Metal parts are sandblasted, degreased, and pre-oxidized, first being plated, if necessary, with e.g. chromium or other metal which will readily pre-oxidize. The glass is preferably applied in suspension to both surfaces to be bonded, these then being brought together and subjected to a heating and cooling cycle which will bond them and result in controlled devitrification of the glass layer. Sealing glass compositions and heat cycles for sealing a Ni-Fe-Co alloy to a zircon-enstatite ceramic and a high alumina ceramic, and for sealing a Ni-Fe alloy to a forsterite ceramic are given, the alloy being chromium plated and fired in "wet" hydrogen to form a chrome-oxide layer. Heating may be carried out by gas flame or high-frequency electricity in a reducing atmosphere. Specifications 924,996, 930,931 and 943,599 are referred to.
