Abstract
Official abstract text for this publication.
A sliding member of the present embodiment includes a bearing alloy layer and a coating layer provided on a sliding surface side thereof. The coating layer has a resin binder with sulfide particles dispersed therein. A covering portion is provided over specific particles and is made of metal oxide comprising the same metal element as a metal element constituting the sulfide particles. When measured by an X-ray photoelectron spectroscopy and an X-ray diffraction method, a ratio of a peak height of the metal oxide to a peak height of metal sulfide by the X-ray photoelectron spectroscopy is from 0.10 to 0.50, and a ratio of the peak height of the metal oxide to the peak height of the metal sulfide by the X-ray diffraction method is 0.10 or less.
First claim
Opening claim text (preview).
What is claimed is: 1. A sliding member comprising: a bearing alloy layer, and a coating layer provided on a sliding surface side of the bearing alloy layer, wherein the coating layer has: a resin binder, sulfide particles dispersed in the resin binder, and made of metal sulfide, and a covering portion provided over specific particles located on the sliding surface side of the coating layer among the sulfide particles dispersed in the resin binder, the covering portion being made of metal oxide comprising the same metal element as a metal element constituting the sulfide particles, and when a surface of the coating layer on the sliding surface side is measured by an X-ray photoelectron spectroscopy and an X-ray diffraction method, a ratio of a peak height of the metal oxide to a peak height of the metal sulfide by the X-ray photoelectron spectroscopy is from 0.10 to 0.50, and a ratio of the peak height of the metal oxide to the peak height of the metal sulfide by the X-ray diffraction method is 0.10 or less. 2. The sliding member according to claim 1 , wherein the metal element is at least one or more selected from the group consisting of Mo, W, Sn, Ti and Zr. 3. A bearing device comprising: a shaft member having a surface roughness Rz of 0.8 μm or more, and a sliding member according to claim 1 that slides against the shaft member, and supports the shaft member.
