Abstract
A composite antifriction bearing comprises a base layer 1 of metal alloy containing at least copper and lead, a surface layer 3 of lead alloyed with an anti-corrosion addition (e.g. tin or indium) and a diffusion barrier 2 arranged between the surface layer and the base layer, wherein the diffusion barrier comprises copper in combination with boron. The diffusion barrier prevents depletion of the anti- corrosion agent from the surface layer. The diffusion barrier and the surface layer may be applied by electrodeposition. <IMAGE>
Description
SPECIFICATION
Composite antifriction bearing
The invention relates to a composite antifriction bearing comprising a base layer of a metal alloy containing at least copper and lead, a surface layer of lead alloyed with an anticorrosion addition and a diffusion barrier arranged between the surface layer and the base layer, wherein the diffusion barrier siows down the reaction rate between the anti-corrosion addition of the surface layer and components of the base layer.
The base layer comprises generally a copperlead alloy or a lead-bronze alloy.
The purpose of the surface layer is to increase the tolerance of the bearing to misalignment, dirt and wear debris, to enable it to operate against unhardened journals and to protect the bearing against corrosion.
The prime purpose of the anti-corrosion addition in the surface layer is to provide resistance to corrosion by hot-oxidised lubricating oils, or lubricating oils contaminated by partially decomposed fuels. The anti-corrosion addition generally is tin or indium.
From U.S. patent specification No. 3,307,926, a diffusion barrier is known consisting of a tinnickel alloy for a composite antifriction bearing having a tin containing surface layer.
It is an object of the invention go provide a composite antifriction bearing having an improved diffusion barrier diminishing depletion of the anti-corrosion addition from the surface layer to a greater extent than the known diffusion barriers. For this purpbsk the composite antifriction bearing according to the invention comprises a base layer of a metal alloy containing at least copper and lead, a surface layer of lead alloyed with an anti-corrosion addition and a diffusion barrier arranged between the surface layer and the base layer, wherein the diffusion barrier comprises copper in combination with boron.
It is another object of the invention to provide a method of manufacturing such a composite antifriction bearing. For this purpose said method comprises applying copper in combination with boron to the base layer by an electro-deposition process, in order to form the diffusion barrier and then applying the surface layer on top of the diffusion barrier.
The invention will now be further explained with reference to the accompanying drawings, wherein
Fig. 1 shows a perspective view of one half of an embodiment of a composite antifriction bearing according to the invention.
Fig. 2 shows a cross-section 11-11 of the embodiment of Fig. 1.
In the composite antifriction bearing as shown, the base layer is indicated by reference numeral 1, which base layer 1 is a metal alloy containing at least copper and lead, such as a copper-lead alloy or a lead-bronze alloy. The base layer 1 may be supported at the outside periphery by a support body (not shown), for example made of steel. The inner side of the base layer 1 is bonded to a diffusion barrier 2 comprising copper in combination with boron. The inner side of the diffusion barrier 2 is bonded to a surface layer 3.
The surface layer 3 may have a thickness in the range of from about 6 ,um to 25 ,um. The surface layer 3 may be a lead-tin alloy, wherein the quantity of tin is in the range of from about 2% to about 20% by weight. Instead the surface layer 3 may be a lead-indium alloy, wherein the quantity of indium is in the range of from about 3% to about 10% by weight. The inner surface 4 of the surface layer 3 is adapted to cooperate with a journal (not shown), wherein the surface 4 and the journal may be separated by a film of a suitable lubricant.
The bearing according to the invention is manufactured by applying copper in combination with boron to the base layer 1 in order to form the diffusion barrier 2 by an electro-deposition process.
In this copper-boron electro-deposition process, an electroplating bath is used having the following composition:
Concentration
in gll of
aqueous
Substance solution
Cupric sulphate, CuSO4.5H20 30 Boric acid, H3BO3 40
The operating conditions are as follows:
Temperature 20-250C Cathode current
density 0.5-1.0 A/dm2
The anode/cathode area ratio is for example 1:1 and the anodes are of copper.
The resulting product is Cu-B with a boron content of up to 0.02% wt.
Finally the surface layer 3 is applied on top of the diffusion barrier 2. This surface layer 3 can for example be applied by an electro-deposition process, which is a process known in the art as such.
