Abstract:
Provided is a sliding material including a substrate; and a copper alloy layer bonded to the substrate. The copper alloy includes 2.0 to 15.0% by mass of tin. The copper alloy layer includes a sliding body part including a sliding surface, and a gradient region including a bond surface with the substrate. A tin concentration in the gradient region reduces from the sliding body part toward the bond surface. A method for producing the siding material is also provided. The method includes preparing the substrate having a first surface and a second surface opposite to the first surface; melting the copper alloy; casting the molten copper alloy on the first surface of the substrate; and solidifying the copper alloy unidirectionally by cooling the substrate from the second surface by a coolant.

Claim (Index 12):
The method according to  claim 9 ,\n wherein the step of preparing the substrate comprises forming a cylindrical body from one or more substrate materials, and the step of casting comprises casting the molten copper alloy in an inner surface of the cylinder body while rotating the cylindrical body on a central axis of the cylinder.
