Title:
SLIDE MEMBER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/061333
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a slide member in which the bonding strength between a Bi-containing copper alloy layer and a substrate is enhanced; and a method for manufacturing the slide member. The slide member according to the present invention has a substrate and a copper alloy layer. The copper alloy layer comprises a copper alloy containing 4.0-25.0 mass% of Bi and has a structure in which Bi phases are scattered in a copper alloy structure. The volume ratio of Bi phases in the region of the copper alloy layer extending 10 μm from the bonding interface with the substrate is 2.0% or less. The slide member is manufactured by casting a molten copper alloy onto the substrate and causing the copper alloy to unidirectionally solidify.
