Title:
SLIDE MEMBER
Document Type and Number:
Japanese Patent JP2021089008
Kind Code:
A
Abstract:
To provide a slide member improved in abrasion resistance by improving strength of a resin overlay layer without increasing a coefficient of friction.SOLUTION: A slide member includes a resin overlay layer at a slide surface side of a bearing alloy layer. The resin overlay layer has a resin binder, and 20 vol.% or more of solid lubricant particles of anisotropic shape, dispersed in the resin binder. When a slide surface is defined as 0°, a virtual axis vertical to the slide surface is defined as 90°, an angle between a straight line and a major axis of the particles is defined as θ, and the total number of the particles included in an arbitrary observation region of the resin binder is defined as N, a ratio R1=N1/N of the number N1 of the first particles in which an angle θ of the major axis of the particles satisfies 70°≤θ≤90°, satisfies 3%≤R1≤20%, and a ratio R2=N2/N of the number N2 of the second particles in which the angle θ of the particles satisfies θ≤20°, satisfies 35%≤R2≤65%.SELECTED DRAWING: Figure 1
