PURPOSE:To produce easily a sliding member having improved adhesion strength with a sliding material formed with an overlay layer via an Ni layer on a substrate by providing an adhesive layer to adhere tightly the Ni layer and the overlay layer between the two layers. CONSTITUTION:An Ni layer 4 having about 1-3mu thickness is formed by plating on the surface of a substrate 1 constituted of a backing metal 2 consisting of a steel sheet and a lining layer 3 consisting of a copper-lead alloy and having about 0.2-0.4mm. thickness. An adhesive layer 5 having about 0.1-4mu thickness is formed on the layer 4 and an overlay layer 6 consisting of a tin-lead alloy and having 5-30mu thickness is formed on the layer 5 and further a surface layer 7 having about 1mu thickness consisting of tin is formed thereon. The thickness of the layer 5 is made about <=5mu and >=1 kinds among tin, zinc, Sb and copper (or an alloy consisting essentially thereof) are used for said layer. Said layer, when subjected to a heat treatment, solutionizes the Ni layer 4 and the overlayer layer 6 thereby accelerating formation of the intermetallic compd. and adhering tightly the two layers. |
