Abstract
(EN)
A material, which is useful as an abrasion-resistant member, a photocatalytic material capable of exhibiting a function at a high level, a material for photoelectric conversion elements and the like, is produced without requiring the employment of complicated processes or complicated handling procedures which are disadvantages of conventional techniques. A method for producing a surface-treated metal titanium material or titanium alloy material, said method being characterized by comprising (1) a step of forming a titanium nitride on the surface of a metal titanium material and (2) a step of subjecting the metal titanium material having the titanium nitride formed on the surface thereof, which is produced in step (1), to a heating treatment in an oxidative atmosphere; a production method as mentioned above, said method being characterized by involving, between the above-mentioned steps (1) and (2), a step of carrying out the anodic oxidation of the metal titanium material having the titanium nitride formed on the surface thereof, which is produced in step (1), in an electrolytic solution that cannot etch titanium to thereby form a titanium oxide coating film on the metal titanium material; and a surface-treated material.
