Abstract

711,373. Plain bearings. GLACIER METAL CO., Ltd. Sept. 15, 1952 [Sept. 28, 1951], No. 22689/31. Class 12(1) [Also in Group XXII] A plain bearing or composite material for making a bearing, comprises a backing of steel or steel alloy having a superposed layer consisting of lead or lead base alloy dispersed in a matrix of iron, with a facing layer of soft metal or alloy. A preferred structure is one comprising an interlaced sponge formation of iron and lead, and the product may be compacted so as to be substantially non- porous. The overlay may consist of lead, with up to 10 per cent tin, or with up to 3-10 per cent indium, lead with tin and indium, or. a lead or tin base alloy containing antimony &c., and may be 0.0002 inches to 0.003 inches thick. A barrier layer of nickel &c. 0.0001 inches thick may be applied to prevent tin diffusion. With journals of graphitic cast iron or hard steel a soft overlay may be unnecessary. The bearing or material may be made by sintering iron powder on copper plated steel in a reducing atmosphere so as to form a porous iron structure bonded to the steel, the pores then being filled with lead containing for example 5 per cent tin by re-heating in a reducing atmosphere. In a further method of manufacture a mixture of iron and lead powders is sintered on to the steel backing, and the composite strip is then rolled or otherwise compacted and re-sintered in a reducing atmosphere. When maximum softness is required in curved liners the second sintering operation is deferred until after the forming operation so as to remove any work hardening of the iron matrix. In a further method iron may be sprayed on to the backing. In yet a further modification iron gauze may be copper brazed to a mild steel backing and the lead may be applied in the form of powder or foil, or by strip lining as in Specification 666,528, [Group II], which is referred to. If desired, suf-. ficient lead may be applied to leave a surplus of 0.003 inches to 0.004 inches on the surface to form an overlay after boring. Small amounts of other metals can be added either to the lead or to the iron, e.g. manganese or nickel to the iron powder. In all embodiments, an overlay or facing layer of a soft metal or metal alloy may_ be subsequently applied by electro-deposition or otherwise.
