Abstract
A plastics alloy for a bearing material comprising polyphenylene sulphide and polyether ether ketone. The alloy is formed by powder mixing, melt blending or solvent blending and applied to a metal backing either as a sheet, or in solution or in powder form. The alloy is heated and roll bonded to the backing.
Claims18
A method of making a plain bearing comprising a plastics alloy bearing layer and a metal backing, the method including the steps of mixing together a polyarylene sulphide and a polyether ketone to form an alloy, applying said alloy to said metal backing and bonding said alloy to said backing.
[8. A plastics alloy comprising a polyarylene sulphide and an aromatic polyether ketone.]
[9. An alloy according to claim 8 wherein said polyarylene sulphide is polyphenylene sulphide.]
[10. An alloy as claimed in claim 9 in which the polyphenylene sulphide comprises from 20 to 50% by weight of the alloy.]
[11. An alloy according to any one of claims 8, 9 and 10 wherein said polyether ketone is polyether ether
- ketone.]
A laminated bearing comprising a metal backing member and a plastics alloy bearing member of a polyarylene sulphide and an aromatic polyether ketone bonded to said backing member.
