Abstract:
The present invention addresses the problem of providing a sliding member covered with a DLC coating with which microfractures in a sliding surface due to development of cracks are less likely to occur, and an increase in abrasive wear can be suppressed. The problem is solved by a sliding member having on an outer peripheral sliding surface a DLC coating, wherein the amount of work of plastic deformation which is measured by a nanoindentation test is within a specific range.
