Abstract

1387478 Soldering BRITISH LEYLAND TRUCK & BUS DIVISION Ltd 23 July 1973 [28 July 1972] 35290/72 Heading B3R [Also in Division C7] In joining porous ceramic articles the surfaces to be joined are impregnated with a metallic salt, the salt is reduced by heating in a reducing atmosphere and the resulting metallized surfaces on the articles are brazed together. Two articles, for use in a gas turbine, made of porous silicon nitride are painted with an aqueous solution of ammonium molybdate which is allowed to dry and the articles are heated in a hydrogen furnace at 600‹ C. and cooled while still in the hydrogen. Carbon monoxide may be employed instead of hydrogen. The metallized articles are then held in a jig with silver or nickel based brazing alloy between them and are heated in a reducing or inert atmosphere to effect brazing. Instead of molybdenum, nickel or silver may be used to metallize the articles, when the salt could be a nitrate.
