After that, when the surface to which the flame was applied was brought into contact with the flat surface of a 30 mm thick stainless steel block and cooled, the fine columns of white acid-titanium power grew on most of the stainless steel plate surface. And a small piece member in which a large number of continuous narrow protrusions having white acid-titanium force and fine columns standing on the protrusions are exposed on the thin film. separated.
- a commercially available acid titanium sol (STS-01 from Ishihara Sangyo Co., Ltd.) was spin-coated on a 0.3 mm thick titanium plate, and then heated to form a titanium plate having an acid titanium film with improved adhesion. .
- Test Example 1 (Attraction hardness test: pencil method)
- Test Example 2 (Chemical resistance test)
- the member in which the layer with the fine pillars exposed on the substrate surface obtained in Examples 1 to 7 was exposed was immersed in 1M sulfuric acid aqueous solution and 1M sodium hydroxide aqueous solution for 1 week respectively, washed with water, After drying, the above-mentioned pulling hardness test: the pencil method was carried out. The results are shown in Table 1. That is, even when a 9H pencil is used for all specimens No damage was observed, and it was confirmed to have high chemical resistance.
- Test Example 3 Heat resistance test
- the member with the exposed layer of fine pillars exposed on the surface of the substrate obtained in Examples 1 to 7 was placed in a tubular furnace, and the temperature was raised from room temperature to 500 ° C over 1 hour in an air atmosphere. After holding at a constant temperature of 500 ° C. for 2 hours and further allowing to cool to room temperature over 1 hour, the above-mentioned scratch hardness test: the pencil method was carried out. The results are shown in Table 1. In other words, no damage was observed even when 9H pencil was used for all the test pieces, and it was confirmed that the test piece had high heat resistance.
- Test Example 4 Anti-fouling test
- a member having a surface area of 8 cm 2 in which fine pillars stand on the surface of the substrate obtained in Example 4 and the layer is exposed, and a surface area of 8 cm 2 having the titanium oxide film obtained in Comparative Example 1 are obtained.
- the deodorizing test was conducted using 2 titanium plates. Specifically, each sample was immersed in 80 mL of an aqueous methylene blue solution adjusted to a concentration of about 12 molZL so that the influence of concentration reduction due to initial adsorption could be ignored, and then manufactured by Matsushita Electric Industrial Co., Ltd.
- Visible light was irradiated by a fluorescent lamp equipped with a UV cut filter, and the absorbance of a methylene blue aqueous solution at a wavelength of 660 nm was measured with a water quality inspection apparatus DR Z2400 manufactured by HACH at each predetermined irradiation time. The result was as shown in FIG.
- Test Example 5 (Crystal structure and bonding state)
- the acceleration voltage is measured with an X-ray photoelectron spectrometer (XPS): 10 kV, target: A1, Ar ion sputtering was performed for 2700 seconds, and analysis was started. If this splatter speed is 0.664 AZs equivalent to SiO film, the depth is about 173 nm. That XPS
- the result of the analysis is as shown in FIG.
- the highest peak appears when the binding energy is 284.6 eV. This is judged to be a C H (C) bond commonly found in Cls analysis.
- the next highest peak is seen when the binding energy is 281.6 eV. Since the bond energy of Ti—C bond is 281.6 eV, it is judged that C is doped as Ti C bond in the fine column of Example 3.
- As a result of XPS analysis at 14 points at different heights of the fine column similar peaks appeared near 281.6 eV at all points.
- a titanium disc having a diameter of 32 mm and a thickness of 0.3 mm was used as a test piece, and its surface was heated by an acetylene combustion flame so that the surface temperature was maintained at about 1150 ° C.
- the first test piece was allowed to cool after heating was stopped at a heating time of 120 seconds.
- heating was stopped at 180 seconds and allowed to cool.
- the third specimen was heated for 480 seconds and immediately cooled by bringing the surface to which the flame was applied into contact with the flat surface of a 30 mm thick stainless steel block. By this cooling, the surface of the titanium plate was peeled off from the thin film, and from there, a member was obtained in which a layer in which fine columns of white acid-titanium force were erected was exposed.
