KITCHEN PRODUCT AND DISHWASHER PROVIDED WITH CARBON-DOPED TITANIUM OXIDE SURFACE LAYER

摘要

PROBLEM TO BE SOLVED: To provide a kitchen product provided with a carbon-doped titanium oxide surface layer functioning as a visible light response type photocatalyst, having a photocatalytic activity, excellent in a bacterial action, a sterilization action and a deodorization action, having high film hardness and excellent in durability (a peeling off-proofing property, abrasion resistance, chemical resistance, heat resistance and corrosion resistance) and an ultra-hydrophilicity.;SOLUTION: At least a part of a surface layer of a substrate comprises titanium or the like and a carbon-doped titanium oxide surface layer in which carbon is doped in the state of Ti-C bond is formed on at least a part of the surface of the surface layer. Alternatively, a layer in which a large number of fine columns comprising titanium oxide or a titanium alloy compound stand is exposed to at least a part of the surface of the surface layer and the fine columns are carbon-doped.;COPYRIGHT: (C)2006,JPO&NCIPI
