    摘要： An inspection method which quantitatively and simply assures a nitrogen concentration in a carbonitriding-treated bearing part, and a bearing part and a bearing for which a nitrogen concentration is quantitatively assured are obtained. An inner race, an outer race, and balls as bearing parts are each a bearing part made of JIS standard SUJ2 and having a carbonitrided layer formed in a surface thereof, wherein, after heat treatment at a heating temperature of 500° C. for a retention time of one hour is performed, a Vickers hardness at a position with a depth of 30 μm from the surface is higher than a Vickers hardness at a core portion, which is a region where the carbonitrided layer is not formed in a thickness direction of the bearing part, by not less than 130 HV.

    摘要： A laminated film is provided which exhibits excellent durability even when formed over a surface of a member (in particular, sliding member) to be used under a high pressure of contacted surface of 2.0 GPa or more. The laminated film includes an intermediate layer which contains one or more compounds selected from the group consisting of a carbide, a boride, and a boron carbide compound of a metal element, and which has a hardness measured by a nanoindentation method (hereinafter referred to as a “nanoindentation hardness”) of not less than 20 GPa nor more than 35 GPa and a thickness of not less than 5 μm nor more than 10 μm, and a diamond-like carbon film which is formed over the intermediate layer, and which has a nanoindentation hardness of not less than 25 GPa nor more than 35 GPa and a thickness of not less than 0.3 μm nor more than 1.0 μm.

    摘要： A composite bearing member 10 includes: a bearing sliding material 20 whose surface contacts a rotating portion; a bearing base material 30 made of a material different from a material constituting the bearing sliding material 20; and a joining layer 40 joining the bearing sliding material 20 and the bearing base material 30. Further, the bearing sliding material 20 has a sliding layer 50 sliding the rotating portion on a surface. Furthermore, the bearing sliding material 20 has, between the sliding layer 50 and the joining layer 40, a composition graded layer 60 which dispersedly contains the same metal material as a metal material constituting the joining layer 40 and in which a content of the metal material is increased toward the joining layer 40.
