発明の名称 (英語) SLIDING METHOD, PRODUCTION METHOD FOR SLIDING STRUCTURE, SLIDING STRUCTURE, AND DEVICE
発明の概要(英語) In the present invention, a first sliding member and a second sliding member each have a sliding surface comprising a hard carbon film. Protrusions (6) are present on sliding surface of the first sliding member. The friction work per unit area of the sliding surface of the first sliding member is less than the friction work per unit area of the sliding surface of the second sliding member. Conformity processing of the first sliding member and the second sliding member is performed in a fluid-free environment and then the first sliding member and the second sliding member are caused to slide in fluid, until the average height of the protrusions in the first sliding member is less than the amount of elastic deformation that occurs in the first sliding member as a result of the load from the second sliding member when the first sliding member and the second sliding member are caused to slide. As a result, the present invention enables sliding members having a hard carbon film to slide without causing separation, in a fluid environment particularly a water environment.
