METHOD FOR MANUFACTURING EDIBLE OIL DETERIORATION PREVENTING MEMBER, AND EDIBLE OIL DETERIORATION PREVENTING MEMBER |
摘要 |
An object of the present invention is to produce a member useful for preventing edible oil from degrading by performing simple, economical, and safe steps. A method for producing an edible oil degradation-preventing member, comprising the steps of:
(1) forming titanium nitride on the surface of a metallic titanium material or titanium alloy material by one treatment method selected from the group consisting of a heat treatment under an ammonia gas atmosphere and a heat treatment under a nitrogen gas atmosphere, at a heating temperature of 750°C or higher;
(2) anodizing the metallic Titanium material or titanium alloy material with the titanium nitride formed on the surface thereof obtained in step (1) by applying a voltage of 10 V or more in an electrolyte solution having no etching effect on titanium, thereby forming a titanium oxide film; and
(3) heating the metallic titanium material or titanium alloy material with the titanium oxide film formed on the surface thereof obtained in step (2) at a temperature of 400°C or higher in an atmosphere selected from an air atmosphere, a mixed atmosphere of oxygen gas and nitrogen gas, and an oxygen gas atmosphere. |
