Abstract

714,681. Coating with metals. GLACIER METAL CO. Ltd. Jan. 18. 1952. [Feb 5, 1951; April 25, 1951], Nos. 2796/51 and 9639/51. Class 82 (2) [Also in Group XXII] in a method of making plain bearing surfaces comprising a copper-clad structure containing 5-50 per cent. of lead bonded to a steel &c. backing, a copper sponge structure is subjected to heat treatment at sintering temperature while immersed in molten lead. Copper powder is applied from a hopper 2 to form a layer 3 on a copper-plated steel strip 1 which is continuously fed through a sintering furnace 4 oontain:ng a reducing atmosphere of hydrogen or a mixture of hydrogen and nitrogen in which the powder becomes partially sintered and bonded to the steel backing The composite strip then passes through a bath 5 of molten lead protected from oxidation by a floating cover or a gas blanket and which is heated by burners 6 to have a temperature gradient so that the strip is near sintering temperature at entry and is cooled to a temperature just above the melting point of lead as it leaves. The strip then passes through a chamber 7 where it is wiped to remove excess lead and cooled in a neutral or reducing' atmosphere before passing into the open air for cooling The bi-metallic strip so formed may be used for making bearing liners, sleeves and external bearing surfaces, thrust washers &c. In a modified process the partially sintered strip is severed into lengths which are treated in batches in a chamber containing a reducing gas which is heated by a bell-type electric furnace. After the temperature has been raised sufficiently to reduce all. oxides on the copper sponge, molten lead is introduced into the chamber, and heated near sintering temperature after which it is allowed to cool and is run off just before it solidifies. In another example the copper lead layer is formed on the inner face of a tube by spinning the tube between end plates with copper powder inside while the tube is heated in a neutral atmosphere to bring about partial sintering, molten lead then being introduced into the tube. In all examples modifications in the spongy texture of the copper may be brought about by the introduction of small percentages of tin, silver nickel, arsenic or silicon powders. Specification 676,209 is referred to.
