Sliding member for engines of motor vehicles, includes bearing alloy layer, and composite plating film made of lead alloy containing copper and co-deposited inorganic particles

摘要

Sliding member comprises a bearing alloy layer (2), and a composite plating film (4). The composite plating film is made of a lead alloy containing 0.1-10 mass % copper and 0.3-25 vol.% co-deposited inorganic particles, and the outermost surface layer of the composite plating film. A sliding member comprises a bearing alloy layer and a composite plating film provided on the bearing alloy layer. The composite plating film is made of a lead alloy containing 0.1-10 mass % copper and 0.3-25 vol.% co-deposited inorganic particles, and the outermost surface layer of the composite plating film, which has a thickness proportion of 10-40 % to the entire thickness of the composite plating film, does not contain inorganic particles and copper.
