Abstract: Provided is a sliding member which has high seizure resistance though an overlay layer comprising Ag as the main component is used therein. The sliding member of an embodiment comprises a base and an overlay layer which is disposed on the sliding-side surface of the base and which comprises Ag as the main component and contains Al. The overlay layer comprising Ag as the main component is relatively soft. Due to this, the overlay layer comprising Ag as the main component can ensure high seizure resistance even when the use of Pb is avoided. Furthermore, the overlay layer comprising Ag as the main component has excellent thermal conductivity. Due to this, frictional heat generating at the sliding part rapidly dissipates to the base side.

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.
