Slide member and method of manufacturing slide member

摘要

A slide member provided with an overlay composed of a Bi-based material and a method of manufacturing such a slide member are provided. The slide member includes a substrate 12; and an overlay 13 including Bi or a Bi alloy provided over the substrate. A surface portion of the overlay 13 includes an oxide layer 16 in which a bismuth oxide is scattered. The content of the bismuth oxide in the oxide layer 16 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.
