Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a decorative body in which a surface layer having various hues is provided on the surface of a substrate having heat resistance.
[0002]
[Prior art]
An object having a light-interfering surface layer emits a unique subtle luster and is therefore preferably used as a decorative body.
As a method for producing such a decorative body, the present applicant forms a thin film on the surface of the substrate subjected to glazing by any one of vacuum deposition, sputtering, ion plating, vapor phase growth and plating, This is subjected to a high temperature treatment at a temperature at which the wrinkles become semi-fluid, and a method of manufacturing a decorative body (see Patent Document 1) for forming a light-interfering surface layer showing an aesthetic pattern, and a wrinkle surface of a wrinkled substrate. A thin film is formed by any one of vacuum deposition, sputtering, ion plating, vapor phase growth and plating, and an inorganic compound thin film is formed thereon by any one of the above methods. The manufacturing method (refer patent document 2) of the decorative body which heat-processes by the temperature used as this, and forms the light coherent surface layer which shows an aesthetic pattern was proposed.

[Problems to be solved by the invention]
The present invention provides a method for manufacturing a decorative body having a variety of subtle beauty by adding the polychromaticity associated with the absorption of a specific wavelength of light to the conventional technology mainly for the beauty of interference colors. The task is to do.
[0005]
[Means for Solving the Problems]
Preparation of decorative material of the present invention is to deposit a thin film on釉面substrate subjected to glaze, the thin film as a plurality of layers, which was hot at a temperature of glaze is semifluid, diverse Forming a surface layer having a hue, wherein the thin film is made of the same kind of material, and includes at least one pair of adjacent unit layers having different lamination speeds, thereby reducing the density of these unit layers to each other. It has a hue and brightness due to specific wavelength absorption of light .
In the present invention, as the substrate, heat resistant materials such as metals such as copper, silver, gold, iron, steel, stainless steel and other alloys, ceramics, ceramics, and glass are used.
There are two types of pots: pottery for ceramics and pots for metal (enameled porcelain, cloisonne pot). Use a pot suitable for the material of the substrate and fire it at a temperature corresponding to the type of pot. Moreover, a conventionally known method is adopted as a method for applying wrinkles to the substrate.
[0006]
The thin film provided on the surface of the base is formed by stacking a plurality of unit layers.
The plurality of unit layers are Ti, Au, Ag, Al, Fe, Cr, Ni, Cu, Pt, Pd, Zn, Mn, Mg, Y, Zr, Si, Pb, Sn, In, Sb, Co, Mo, It consists of a metal such as Ce, Pr, Eu, Er, or a metal compound.
The thickness of each unit layer is arbitrarily controlled according to the material, the number of layers, etc. by changing the lamination time.
Each unit layer becomes dense as the stacking speed increases if the temperature of the substrate is constant, and becomes coarse when the stacking speed is low, so by changing the combination of the stacking speeds of each unit layer, The beauty of the surface layer changes in various ways. The relationship between the density of the unit layer and the deposition rate shows the same tendency in vapor deposition, sputtering, vapor phase growth, and the like.
[0007]
Thus, what formed the thin film on the surface of the base | substrate is processed at high temperature by an electric furnace, a ceramic furnace, a burner heating, infrared heating, induction heating, etc. The temperature of the high-temperature treatment varies depending on the material of the thin film and the basket, but is usually 300 to 1600 ° C.
Then, the thin film is oxidized from the surface, and a complex and beautiful hue is exhibited by the oxidation of the multilayer unit layer. The color of the thin film varies depending on how deep it is oxidized from the surface, and each unit layer is fine. Therefore, it is necessary to carefully control the temperature and time for high temperature treatment.
Also, the material of the single-position layer, number of layers, layer thickness, by changing the lamination speed, it is possible to variously change the hue and brilliance.
[0008]
By high-temperature treatment, the soot is heated and becomes semi-fluid, and after reaching the glass transition point and becoming a glass state, the specific volume and the coefficient of thermal expansion suddenly increase. Cracks, bubble holes, bumps, etc. occur and irregular patterns appear on the surface of the thin film.
As a result of the high-temperature treatment, the thin film is firmly bonded to the ridge, so that the wear resistance is improved.
[0009]
At least one of the plurality of unit layers may be made of a single metal. Here, the metal simple substance excludes metal compounds such as oxides, hydroxides and sulfides. The simple metal is easily dissolved in the cocoon like a metal compound and does not lose the interference color, and a portion oxidized by the high temperature treatment disappears, but it is easy to maintain a beautiful gloss .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to examples. In each example, the deposition is vacuum deposition using an electron beam, and at the start of deposition, the substrate is evaporated at a heating temperature of 230 ° C. and a deposition start pressure of 2 × 10 ⁻³ Pa to obtain the thickness of each unit layer. Describes the value of control by the quartz resonator sensor.

Example 1
A surface 2 of the substrate 1 made of alumina is provided with ridges 2, and the first unit layer 4, the second unit layer 5, the third unit layer 6, and the fourth unit are sequentially formed on the surface of the ridge 2 from the substrate 1 side. A thin film 3 composed of the layer 7, the fifth unit layer 8 and the sixth unit layer 9 was deposited.
The first unit layer 4 deposits Cr to a thickness of 2850 mm at 4 mm / sec, the second unit layer 5 deposits Cr to a thickness of 50 mm at 1 mm / sec, and the third unit layer 6 forms Au. The first unit layer 7 is deposited at a thickness of 30 mm at a rate of 1 mm per second, Fe is deposited at a thickness of 10 mm at a rate of 0.2 mm per second, and the fifth unit layer 8 is 10 mm thick at a rate of 0.2 mm per second for Co. The sixth unit layer 9 is formed by depositing Cr to a thickness of 25 mm at a rate of 0.2 mm / second.
This was baked at 750 ° C. for 10 to 15 minutes to obtain a black matte surface.
[0012]
Example 2
A ridge 2 was applied to the surface of the substrate 1 made of alumina, and a thin film 3 was deposited on the surface of the ridge 2. The thin film 3 includes a first unit layer 4 in which Ti is vapor-deposited to a thickness of 1300 Å at a rate of 1.5 秒 per second and a second unit layer 5 in which Ti is vapor-deposited to a thickness of 1200 Å at a rate of 3 毎 per second. It consists of.
Next, this was heated and fired several times at 725 ° C. for 1 minute.
Although Ti is a metal that hardly causes cracks, a surface layer of titanium oxide having fine cracks was obtained by laminating two unit layers having different crystal densities.
