Abstract: A sliding bearing includes a backing layer, a bonding layer with at least one fluorination-treated surface, and a sliding layer. A method for preparing the sliding bearing includes performing a fluorination treatment on a surface of the bonding layer, placing a surface of the bonding layer on a surface of the backing layer, and placing a surface of the sliding layer on a surface of the bonding layer to form a laminated assembly, heating and pressurizing the laminated assembly, and cooling the laminated assembly in a pressurized state.

Abstract: The present disclosure discloses a sliding bearing comprising a fluorination-treated bonding layer, the sliding bearing comprising a sliding layer, a backing layer and a bonding layer with at least one fluorination-treated surface. The present disclosure further provides a method for preparing said sliding bearing. While maintaining bonding stren gth between sliding layer and backing layer in the sliding bearing, the present disclosure provides a bonding layer of a lower content of fluorine and thereby minimizes the cost of raw materials and influences to the environment.
