Abstract
Official abstract text for this publication.
A sliding member includes a base layer including soft particles made of a soft material softer than a matrix and deposited in the matrix, and a soft layer made of the soft material formed on a surface of the base layer. A boundary portion is formed between crystal grains that have a unique crystal grain structure of the soft particles and crystal grains that have a unique crystal grain structure of the soft layer. An anodic oxidation film of the soft material is formed on the boundary portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sliding member, comprising: a base layer comprising soft particles made of a soft material deposited in a matrix; and a soft layer made of the soft material, wherein the soft material is softer than the matrix, wherein the soft material is formed on a surface of the base layer, wherein a boundary portion is formed between crystal grains of the soft particles and crystal grains of the soft layer, wherein a structure of the crystal gains of the soft particles is different from a structure of the crystal grains of the soft layer, and wherein an anodic oxidation film of the soft material is formed on the boundary portion. 2. The sliding member according to claim 1 , wherein the matrix is made of Cu alloy, and the soft material is Bi. 3. A sliding bearing, comprising: a base layer comprising soft particles made of a soft material deposited in a matrix; and a soft layer made of the soft material, wherein the soft material is softer than the matrix, wherein the soft material is formed on a surface of the base layer, wherein a boundary portion is formed between crystal grains of the soft particles and crystal grains of the soft layer, wherein a structure of the crystal grains of the soft particles is different from a structure of the crystal grains of the soft layer, and wherein an anodic oxidation film of the soft material is formed on the boundary portion. 4. The sliding bearing according to claim 3 , wherein the matrix is made of Cu alloy, and the soft material is Bi.
