Abstract
Abstract This invention is for providing a bearing lining on a backing, for example of aluminum, and uses polyphenylene sulphide which has good bearing properties, in combination with a base comprising a component of a metal from Group I or Group II of the Periodic Table, to effect a good bond between the lining and the backing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
74 words
A plain bearing comprising a backing of aluminum or aluminum alloy and a coating on the backing and comprising a heat-treated polyarylene sulphide resin incorporating between 0.1 and 5.0% by weight of a strong base comprising a component of a metal from Group I or Group II of the Periodic Table, said base being stable at elevated temperatures up to at least 200° C., for establishing a bond between said backing and said coating.
Claim 2
Dependent Claim
74 words
A plain bearing comprising a backing of aluminum or aluminum alloy and a coating on the backing and comprising a heat-treated polyarylene sulphide resin incorporating between 0.1 and 5.0% by weight of a strong base comprising a component of a metal from Group I or Group II of the Periodic Table, said base being stable at elevated temperatures up to at least 200° C., for establishing a bond between said backing and said coating.
Claim 3
Dependent Claim
14 words
A backing as claimed in claim 1 in which the resin is polyphenylene sulphide.
Claim 4
Dependent Claim
17 words
A backing as claimed in claim 2 in which the resin has been heat treated in air.
Claim 5
Dependent Claim
20 words
A backing as claimed in claim 1 in which the resin and base have been combined in a liquid phase.
Claim 6
Dependent Claim
64 words
A backing as claimed in claim 1 in which the base is selected from the group: Li 2 O, Li 2 CO 3 , Na 2 O, NaOH, K 2 O, KOH, K 2 CO 3 , Be(OH) 3 , BeCO 3 , Mg(OH) 2 , MgCO 3 , CaO, SrO, Sr(OH) 2 , SrCO 3 , BaO, Ba(OH) 2 , BaCO 3 .
Claim 7
Independent Claim
80 words
A method of manufacturing a plain bearing in which a backing of aluminum or aluminum alloy has a bearing lining bonded to it by mixing polyarylene sulphide polymer with between 0.1 and 5.0% by weight of a strong base comprising a component of a metal from Group I or Group II of the Periodic Table, applying the mixture to the backing, and curing the polymer by heating at a temperature of at least 360° C. for at least one hour.
Claim 8
Independent Claim
80 words
A method of manufacturing a plain bearing in which a backing of aluminum or aluminum alloy has a bearing lining bonded to it by mixing polyarylene sulphide polymer with between 0.1 and 5.0% by weight of a strong base comprising a component of a metal from Group I or Group II of the Periodic Table, applying the mixture to the backing, and curing the polymer by heating at a temperature of at least 360° C. for at least one hour.
