Abstract
There is provided a method for producing a surface-treated metallic material, by use of which a metallic material having a stable and excellent sliding characteristic can be produced with a low environmental load without covering the metallic material surface with an oxide film. The method for producing a surface-treated metallic material includes immersing an anode and a cathode in an electrolyte solution, placing a metallic material used as a material to be treated above the surface of the electrolyte solution, and applying a voltage between the anode and the cathode to treat the metallic material surface, the voltage being equal to or higher than a voltage for causing a complete plasma state.
