    摘要： A power transmission shaft which can be evaluated on torsional fatigue strength based on a management indicator different from compressive residual stress in an outer surface. In a power transmission shaft having outer circumferential serrations 1a, 1b, torsional fatigue strength is evaluated by using compressive residual stress at a depth of 30 μm (and 50 μm) from an outer surface of a rising portion of each concave of the outer circumferential serrations 1a, 1b as a management indicator. A high torsional fatigue strength can be secured by having a compressive residual stress of 1150 MPa or more at a depth of 30 μm (and 50 μm) from the outer surface.

    摘要： The coated member production method includes a DLC film forming step of introducing a feedstock gas containing a carbon compound and an oxygen-containing organic silicon compound into a treatment chamber in which a base is accommodated, and applying a voltage to the base at a treatment pressure of not lower than 100 Pa and not higher than 400 Pa to generate plasma to form a DLC film on a surface of the base. Hexamethyldisiloxane, for example, is used as the oxygen-containing organic silicon compound. A DC pulse voltage, for example, is applied to the base in the DLC film forming step.
