    Abstract: The present invention addresses the problem of providing a CrN coating film which has excellent peeling resistance such that peeling thereof starting at a crack is unlikely to occur even in a more severe lubrication environment. The problem is solved by a CrN coating film which has a preferred orientation of 200 as determined by XRD, and in which the X-ray diffraction intensity ratio of the (200) plane with respect to the (111) plane, (200)/(111), is 5.5 or higher, and the ratio of crystal grains of 1 μm or smaller is 85% or higher in a crystal grain size distribution measured by an EBSD analysis.

    Abstract: Provided is a cylinder liner which can reduce the friction of the sliding surface from conventional levels and improve fuel efficiency without increasing oil consumption from conventional levels.
    When the inner circumferential surface of a cylinder liner or cylinder bore used in an internal combustion engine has a first sliding region, a second sliding region, and a third sliding region, and when respective surface roughness Rvk is from 0.05 μm to 0.3 μm, from 0.4 μm to 1.5 μm, and from 0.15 μm to 0.7 μm, a friction can be reduced while maintaining oil consumption.

    Abstract: An outer peripheral surface of a piston ring has a cut surface provided to form a cutout portion between an outer peripheral end portion and a lower surface, the cut surface includes a curved concave surface, an inclination angle of a tangent of the curved concave surface at a point closest to the combustion chamber side on the curved concave surface, with respect to a first virtual line extending in parallel to the lower surface is equal to or greater than 5° and equal to or less than 50°, and in a case where an axial direction width of the piston ring is set as h1, and an axial direction width of the cut surface is set as H, H/h1 is equal to or greater than 0.2 and equal to or less than 0.4.
