CARBON-COATED MEMBER AND PRODUCTION METHOD THEREFOR

摘要

Provided is a carbon-coated member that makes it possible to sufficiently reduce friction by merely covering a surface with a DLC coating. In the carbon-coated member, a DLC coating is used to cover a sliding section in the interior of a cylindrical member. The hardness of the DLC coating is 3.0-10.0 GPa and the kurtosis (Rku) is 27.0 or less.
