Abstract
A sliding member includes a base layer that includes soft particles made of a soft material deposited in a matrix and a soft layer made of a soft material. The soft material is softer than the matrix, the soft layer is formed on a surface of the base layer, and an average epitaxial index of the soft particles at the boundary portion of the sliding member is equal to or greater than 70% and less than or equal to 100%. The epitaxial index of a soft particle at the boundary portion is a ratio of: a portion of a length between a first endpoint and a second endpoint of a soft particle where an edge of the boundary portion is not visible within an area less than 1 μm from the length between the first endpoint and the second endpoint, to the length between the first endpoint and the second endpoint.
Claims8
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 a soft material,
- wherein the soft material is softer than the matrix,
- wherein the soft layer is formed on a surface of the base layer,
- wherein an average epitaxial index of the sliding member is equal to or greater than 70% and less than or equal to 100%,
- wherein the average epitaxial index of the sliding member is an average of all of an epitaxial index of the soft particles at the boundary portion, and
- wherein the epitaxial index of the soft particles at the boundary portion is a ratio of:
- a portion of a length between a first endpoint of a soft particle and a second endpoint of the soft particle where an edge of the boundary portion is not visible within an area not farther than 1 μm from the length between the first endpoint and the second endpoint, to
- the length between the first endpoint and the second endpoint.
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 a soft material,
- wherein the soft material is softer than the matrix,
- wherein the soft layer is formed on a surface of the base layer,
- wherein an average epitaxial index of the sliding member is equal to or greater than 70% and less than or equal to 100%,
- wherein the average epitaxial index of the sliding member is an average of all of an epitaxial index of the soft particles at the boundary portion, and
- wherein the epitaxial index of the soft particles at the boundary portion is a ratio of:
- a portion of a length between a first endpoint of a soft particle and a second endpoint of the soft particle where an edge of the boundary portion is not visible within an area not farther than 1 μm from the length between the first endpoint and the second endpoint, to
- the length between the first endpoint and the second endpoint.
