Abstract
A sliding member includes: a base material; a solid lubricant layer arranged on a surface of the base material; a defect layer having a material defect, disposed in the solid lubricant layer, and being changeable into an ultra low friction layer by mechanical stress more easily than changing from the solid lubricant layer to the ultra low friction layer; and a ultra low friction layer covering a surface of the defect layer.

A sliding member comprising:
- a base material;
- a solid lubricant layer arranged on a surface of the base material;
- a defect layer having a material defect, disposed in the solid lubricant layer, and being changeable into an ultra low friction layer by mechanical stress more easily than changing from the solid lubricant layer to the ultra low friction layer;
- and
- a ultra low friction layer covering a surface of the defect layer.

A method for manufacturing a sliding member comprising:
- preparing a base material;
- forming a solid lubricant layer on a surface of the base material;
- introducing a material defect into the solid lubricant layer, and forming a defect layer which is changeable into an ultra low friction layer by mechanical stress more easily than changing from the solid lubricant layer to the ultra low friction layer;
- and
- placing the defect layer in a sliding environment after the defect layer is formed, and changing the defect layer to the ultra low friction layer by mechanical stress.
