Abstract

884,004. Powder metallurgy. GENERAL ELECTRIC CO. Nov. 17, 1959 [Nov. 19, 1958], No. 38932/59. Class 82(1). [Also in Groups XXII, XXIII and XXXVI] Ceramic surfaces are metallised by applying a powder mixture comprising up to 40% manganese, 50% to 90% of molybdenum and/or tungsten and 1% to 50% by weight of a low alkali lead free borosilicate glass and sintering the coated body in a non oxidising atmosphere such as hydrogen to 1250‹C. During sintering the glass reacts with the manganese and ceramic forming a vacuum tight crystalline interface bonding the metals to the ceramic. The powders are mixed in a liquid vehicle such as acetone, Annyl or methyl acetate or xylene plus a binder such as methyl or isolintyl methacrylate or nitrocellulose and applied to the ceramic by spraying dipping brushing or scrubbing. A solder metallic metal such as nickel and copper may be included in the mixture and the metallised layer may also be coated with nickel or copper e.g. by electroplating followed by sintering at 1000‹C. The metallised ceramic can be used to form vacuum tight ceramicceramic or ceramic-metal seals, an alloy such as a silver copper entectic filler forming the bond between the metallised ceramic and the other component. In Fig. 3 a ceramic body 5 with a metallised layer of molybdenium 7 bonded to the ceramic by the glass reaction layer 8 is united to a metal member 4 by the solder layer 9. Specification 656,724 is referred to.
