Abstract: There is provided a sliding member formed by combining a resin overlay and a soft metal overlay. The sliding member has a soft layer comprising a metallic material with a hardness of less than 40 HV provided under a resin overlay layer comprising a solid lubricant and resin. In the event of contamination by a foreign matter, the soft layer under the resin overlay layer is capable of plastic deformation and the resin overlay layer is capable of partial deformation accompanying the plastic deformation due to the hardness (T1) (μm) of the soft layer and the hardness (T2) (μm) of the resin overlay layer being such that 0.2≤T1/T2≤7.0 and 3.0≤T1≤20.0. Consequently, a foreign matter is desirably embedded and resistance to a foreign matter can be improved. Low friction is maintained by the resin overlay layer even after contamination by a foreign matter.

Abstract: A slide member provided with an overlay composed of a Bi-based material. A slide member includes a substrate; and an overlay including Bi or a Bi alloy provided over the substrate. A surface portion (surface-most portion) of the overlay includes an oxide layer in which a bismuth oxide, is scattered. The content of the bismuth oxide in the oxide layer represented by oxygen content is equal to or greater than 0.5% mass % and equal to or less than 8.0 mass %. The orientation intensity ratio of the main orientation plane of Bi or Bi alloy crystals in the overlay is 50% or greater. The main orientation plane of the bismuth oxide crystals in the oxide layer is the (220) plane or the (201) plane.
