Concerning ornaments.

し７た微細凹凸を形成する法がある。(Prior Art) The present applicant previously proposed Japanese Patent Application No. 1-84326 and Japanese Patent Application No. 1-84326 as a first stage of decoration to give a metal surface beautiful multi-color variable color development which is impossible with painting or chemical coloring. There is a laser pressurization method proposed in No. 229567, in which fine irregularities corresponding to the intensity distribution of interference fringes are formed on a metal surface by irradiation with laser interference light.

様に変化することになる。In other words, the fine irregularities formed by the method described in Section 2 are normally 1μ in diameter, with hundreds of irregularities formed on each scan line of the laser interference light, with the bright areas of the interference fringes being concave and the dark areas being convex. Visible light wavelength range (3800 nm or more)
~7,800 people) gathered closely at pitch intervals. Therefore, a metal surface with such fine irregularities splits and reflects incident light in the same way as a diffraction grating, and the tint of the reflected luster changes in a rainbow-like manner depending on the direction of the incident light and the viewing angle. Become.

性、分光色の彩度の全てにおいて大きく劣る。In addition, as a structure to obtain rainbow-like reflective gloss similar to the above, by forming minute irregularities on the back side of a transparent synthetic resin plate and providing a reflective layer such as aluminum foil on the back side,
A device that performs spectral reflection using a so-called prism effect is known. However, the reflective gloss obtained with such a structure has better clarity, brightness, and spectral color than the reflective gloss obtained when fine irregularities are directly formed on the metal surface using the laser interference light described above. Significantly inferior in all aspects.

Stainless steel and Ni-Cr alloys are examples of metal materials that can easily and reliably form the above-mentioned fine irregularities with a general laser processing machine such as a YAC laser widely used in the industry.

した場合に高級感に欠ける嫌いがある。However, although the above-mentioned stainless steel and Ni-Cr alloy have an extremely beautiful iridescent reflective luster, they reflect scattered light, that is, the base color looks cheap, and when used as an ornament, it gives a luxurious impression. I don't like being lacking.

The purpose is to

A structure is adopted in which corresponding fine irregularities are formed and a precious metal coating is provided on the surface on which the fine irregularities are formed with a thickness that leaves the irregularities on the surface.

It can be easily formed by the laser processing method using laser interference light irradiation disclosed in No. 1 and Japanese Patent Application No. 1-229567.

重厚な美しさが加味される。As mentioned above, the metal surface with the fine irregularities exhibits a reflective luster whose hue changes in a rainbow-like manner depending on the angle of incident light and the viewing direction. Also, the appearance of the above-mentioned fine irregularities on the surface of the coating produces a beautiful iridescent reflective gloss. However, the color of the scattered light reflection, that is, the color of the metal surface that does not produce the above-mentioned rainbow-like coloration based on the spectrum, reflects the ground color of the precious metal itself.For example, gold has a golden color, and silver and platinum have a faint color. It exhibits a unique dull white silver color with low reflectance, giving it a luxurious feel as a decorative item. In addition, the hue of the iridescent emitted luster produced by spectroscopy is also affected by the ground color of the precious metal. For example, if the precious metal is gold, the entire color that changes will have a reddish tinge, while if the precious metal is gold, the color will have a reddish tinge, while if it is silver or platinum, it will have a reddish tinge. Coloring is produced, and in both cases, a more profound beauty is added than the hues produced on the surfaces of stainless steel and Ni-Cr alloys.

地色が透けて見える程度に薄くシても差し支えない。The thickness of the noble metal coating as in No. 2 is preferably 1 μm or less; if it is too thick, the fine irregularities of the base will be buried, the irregular stripes on the surface will become blurred, and it will be difficult to produce a good iridescent color. Note that this thickness may be made thin enough to allow the base color of the underlying stainless steel or Ni-Cr alloy to be seen through.

成される。Figure 1 shows the laser processing process, and the ZY table T
A metal plate M made of stainless steel or Ni-Cr alloy is placed on top of the metal plate M, and the interference light B1 of the laser beam is focused by a processing condensing lens L provided above the metal plate M, and the interference light B1 is focused beyond the focal point of the lens L. The surface of the metal plate M is irradiated at a far position. Therefore, by moving the XY table T in the X direction, the surface of the metal plate M is scanned by the converged interference light B2, so the XY table T must be moved in the Y direction every time this scan is completed. A parallel linear or planar scanning pattern can be obtained. Therefore, every 4 scans, the surface of the metal viM has interference fringes with a 1" cross-pattern within the width of the irradiation spont diameter, as shown in the enlarged view of the imaginary line circle C in Fig. 1. Hundreds of four stripes I corresponding to the bright areas are formed.

A plurality of divided beams J can be constructed by overlapping each other, or by laterally displacing the part of the laser beam, as disclosed in Japanese Patent Application No. +1-229567 mentioned above. It can be constructed by superimposing it on the original beam component.
