Abstract
A plain bearing comprising a backing alloy made of copper alloy or aluminum alloy, a coat layer of synthetic resin formed on the surface of a backing alloy, and a thin film of polytetrafluoroethylene formed on the surface of the coat layer has a lower coefficient friction, improved conformability and distinguished sliding characteristics.
Claims4
A plain bearing, which comprises a backing alloy made of copper alloy or aluminum alloy, a coat layer of synthetic resin formed on the surface of the backing alloy, and a thin film of polytetrafluoroethylene formed on the surface of the coat layer.
A process for producing a plain bearing, which comprises a step of roughening a synthetic resin-to-be-coated surface of a backing alloy, a step of cleaning and activating the roughened synthetic resin-to-be-coated surface, a step of coating the roughened synthetic resin-to-be-coated surface with a synthetic resin, and a step of curing the coated synthetic resin at a temperature of not lower than the melting point of polytetrafluoroethylene, thereby forming a coat layer.
