Document Type and Number:
Japanese Patent JP7227098
Kind Code:
B2
Abstract:
A sliding member (1) includes a back-metal layer (2) including an Fe alloy and a sliding layer (3) including a copper alloy (4) including 0.5 to 12 mass% of Sn and the balance of Cu and inevitable impurities. The sliding layer (3) has a cross-sectional structure perpendicular to a sliding surface (31) of the sliding layer. The cross-sectional structure includes first copper alloy grains (41) that are in contact with a bonding surface (21) of the back-metal layer (2) and second copper alloy grains (42) that are not in contact with the bonding surface (21). The first copper alloy grains (41) has an average grain size D1 and the second copper alloy grains (42) has an average grain size D2. D1 and D2 satisfy the following relations: D1 is 30 to 80 µm; and D1/D2 = 0.1 to 0.3.
