A sliding member includes a bearing alloy layer, a solid lubricant layer, particles and a covering portion. The solid lubricant layer is provided on a sliding surface side of the bearing alloy layer and is deposited on the bearing alloy layer. The particles form the solid lubricant layer and are made of metal sulfide. The covering portion is provided over outermost surfaces of the particles on the sliding surface side and are made of metal oxide including the same metal element as a metal element constituting the particles.

Sliding member and bearing device using the same

A bearing member according to an embodiment of the present invention is formed into a single cylindrical shape or a cylindrical shape divided into arcs along a circumferential direction, and is assembled to a housing on an outer peripheral side of the bearing member. The bearing member includes an outer peripheral surface provided on a side opposed to an inner peripheral surface of the housing. A maximum height Rz (&#x3bc;m) of a surface roughness of the outer peripheral surface is set as 2.00 &#x3bc;m&#x2264;Rz&#x2264;4.00 &#x3bc;m, and a value of ratio between an average protruding-peak height Rpk (&#x3bc;m) and a load length rate Mr1 (%), that is a load curve parameter for the surface roughness is set as 0.010&#x2264;Rpk/Mr1&#x2264;0.100.

A slide member including a base material; and an overlay that is formed over the base material and that consists of Ag or Ag alloy including crystal planes (hk1) represented by Miller indices; wherein a relative X-ray diffraction intensity of crystal plane (200) to a sum of X-ray diffraction intensities of crystal planes (200), (111), (220), (311), and (222) of the overlay ranges between 1%&#x2266;(200)/{(200)+(111)+(220)+(311)+(222)}&#x2266;20% and the relative X-ray diffraction intensity of the crystal plane (200) to the X-ray diffraction intensity of the crystal plane (111) ranges between 1%&#x2266;(200)/(111)&#x2266;30%.

Slide member

The present invention is intended to provide a sliding member which exhibits an excellent anti-seizure property even under starved lubricant conditions. In the present invention, there is provided a sliding member with a structure, in which a coating layer having a sliding surface is adhered to the surface of the base material, wherein the coating layer does not contain a resin binder but has solid lubricant plate crystal particles laminated therein, wherein these solid lubricant plate crystal particles have a lamellar crystal structure in which (001) planes are stacked in parallel, and at least in the sliding surface, the orientation index of the (001) plane of the solid lubricant plate crystal particles is 90% or more.
