Sliding member
Disclosed is a sliding member having a bearing alloy layer, an intermediate layer of Ni or a Ni alloy formed on the bearing alloy layer, and an overlay layer of a Sn alloy containing Cu formed on the intermediate layer. There exist Sn—Cu compounds in the overlay layer, which protrudently extend from the intermediate layer. The hard Sn—Cu compounds contribute to the overlay layer in improving fatigue resistance property. A soft Sn matrix being rich in an outer surface region of the overlay layer is responsible for keeping good conformability to have excellent anti-seizure property.
