Title:
SLIDING MEMBER
Document Type and Number:
WIPO Patent Application WO/2021/112008
Kind Code:
A1
Abstract:
A sliding member provided with a resin overlay layer on the sliding-surface side of a bearing alloy layer. The resin overlay layer has a resin binder and 20 volume% or greater of solid lubricant particles dispersed in the resin binder and having an anisotropic shape. It is assumed that the sliding surface is 0°, a virtual axis perpendicular to the sliding surface is 90°, the angle formed by a straight line and the major axis of the particles is θ, and the total number of particles included in a given observation region of the resin binder is N. In this case, among the particles the ratio R1 = N1/N of the number N1 of first particles for which the angle θ of the major axis is 70° ≤ θ ≤ 90° is 3% ≤ R1 ≤ 20%, and among the particles the ratio R2 = N2/N of the number N2 of second particles for which the angle θ is θ ≤ 20° is 35% ≤ R2 ≤ 65%.
