Abstract:
(EN) The purpose of the present invention is to produce a titanium material, on the surface of which a crystalline titanium oxide film is formed. This titanium material, on the surface of which a crystalline titanium oxide film is formed, is useful as a photocatalyst material that exhibits a high function, a material for photoelectric conversion elements, a wear-resistant member, a member for preventing deterioration of edible oils, and the like. A method for producing a titanium material, on the surface of which a crystalline titanium oxide film is formed, according to the present invention is characterized by comprising: (1) a step for forming a surface roughened material by subjecting the surface of a titanium material to a surface roughening treatment; (2) a step for forming a titanium compound on the surface of the surface roughened material; (3) a step for forming an amorphous titanium oxide film by subjecting the material, on the surface of which a titanium compound is formed, to anodic oxidation; and (4) a step for forming a crystalline titanium oxide film by heating the material, on the surface of which an amorphous titanium oxide film is formed, at a temperature of 300°C or higher in the atmosphere.
(FR) Le but de la présente invention est de produire un matériau de titane, sur la surface duquel est formé un film d'oxyde de titane cristallin. Ce matériau de titane, sur la surface duquel est formé un film d'oxyde de titane cristallin, est utile en tant que matériau photocatalyseur qui démontre une fonction élevée, un matériau pour éléments de conversion photoélectrique, un élément résistant à l'usure, un élément de prévention de la détérioration d'huiles comestibles, et analogue. Un procédé de production d'un matériau de titane, sur la surface duquel est formé un film d'oxyde de titane cristallin, selon la présente invention est caractérisé en ce qu'il comprend : (1) une étape consistant à former un matériau à surface rugueuse en soumettant la surface d'un matériau de titane à un traitement de rugosification de surface ; (2) une étape consistant à former un composé de titane sur la surface du matériau à surface rugueuse ; (3) une étape consistant à former un film d'oxyde de titane amorphe en soumettant le matériau, sur la surface duquel est formé un composé de titane, à une oxydation anodique ; et (4) une étape de formation d'un film d'oxyde de titane cristallin par chauffage du matériau, sur la surface duquel est formé un film d'oxyde de titane amorphe, à une température de 300 °C ou plus dans l'atmosphère.
