Claims
- 1. A sliding and bearing material having a superior wear resisting property, consisting of:
- backing metal;
- an intermediate layer joined to said backing metal;
- a porous metallic layer joined to said intermediate layer; and
- a substance with which said porous layer is impregnated or impregnated-and-coated, said substance being one selected from the following mixtures (A), (B) and (C);
- (A) a first sintered mixture consisting of 0.1 to 45 vol % of one composition selected from a group consisting of tetrafluoroethylene-ethylene copolymer resin and fluoroethylene propylene ether resin, and the balance substantially polytetrafluoroethylene;
- (B) a second sintered mixture consisting essentially of 0.1 to 45 vol % in total of at least two compositions selected from a group consisting of tetrafluoroetheylene-perfluoroalkylvinyl ether copolymer resin, tetrafluoroethylene-ethylene copolymer resin, and fluoroethylene propylene ether resin, and the balance substantially polytetrafluoroethylene; and
- (C) a third sintered mixture consisting essentially of 0.1 to 40 vol % of at least one composition selected from a group consisting of tetrafluorotheylene-perfluoroalkylvinyl ether copolymer resin, tetrafluoroethylene-ethylene copolymer resin, and fluoroethyelene propylene ether resin; 0.1 to 35 vol % of at least one composition selected from a group consisting of a low-melting point solid lubricant, fibrous materials and ceramics and the balance substantially polytetrafluoroethylene, the total of contents of the compositions other than polytetrafluoroethylene being in a range between 0.2 and 70 vol %.
- 2. A sliding and bearing material according to claim 1, wherein said backing metal is of a steel strip, while the intermediate layer is a copper plating layer.
- 3. A sliding and bearing material according to claim 1, wherein said porous metallic layer is of a sintered body of a Cu-base alloy.
- 4. A sliding and bearing material according to claim 3, wherein said Cu-base alloy is a Cu-Sn-Pb alloy.
- 5. A sliding and bearing material according to claim 1, wherein the backing metal is devoid of the intermediate layer.
- 6. A sliding and bearing material according to claim 3, wherein the backing metal is devoid of the intermediate layer.
- 7. A sliding and bearing material according to claim 4, wherein the backing metal is devoid of the intermediate layer.
- 8. The sliding and bearing material of claim 1, wherein said substance is mixture (A).
- 9. The sliding and bearing material of claim 1, wherein said substance is mixture (B).
- 10. The sliding member of claim 1, wherein
- said second sintered mixture consists essentially of 45 vol % in total of at least two compositions selected from a group consisting of tetrafluoroethylene-perfluoroalkylvinyl ether copolymer resin, tetrafluoroethylene-ethylene copolymer resin, and fluoroethylene propylene ether resin, and the balance being polytetrafluoroethylene.
- 11. The resin of claim 10, wherein said substance is mixture (A).
- 12. The resin of claim 10, wherein said substance is mixture (B).
- 13. The sliding and bearing material of claim 1, wherein
- said second sintered mixture consists of 45 vol % in total of at least two compositions selected from a group consisting of tetrafluoroethylene-perfluoroalkylvinyl ether copolymer resin, tetrafluoroethylene-ethylene copolymer resin, and fluoroethylene propylene ether resin, and the balance being polytetrafluoroethylene; and
- said third sintered mixture consists of 0.1 to 40 vol % of at least one composition selected from a group consisting of resin, tetrafluoroethylene-ethylene copolymer resin, and fluoroethylene propylene ether resin; 0.1 to 35 vol % of at least one composition selected from a group consisting of a low-melting point solid lubricant, fibrous materials and ceramics and the balance being polytetrafluoroethylene, the total of contents of the compositions other than polytetrafluoroethylene being in a range between 0.2 and 70 vol %.
- 14. The sliding and bearing material of claim 13, wherein said substance is mixture (B).
- 15. The sliding and bearing material of claim 13, wherein
- said first sintered mixture (A) consists of 0.1 to 45 vol % of fluoroethylene propylene ether resin, and the balance being polytetrafluoroethylene.
- 16. The sliding and bearing material of claim 15, wherein said substance is mixture (A).
