The surface of the component can be prevented from being discolored or scratched during the next laser processing step. In addition, in the gold plating process using the electroplating method after laser processing, since the concave patterns or letters created by laser processing expose the stainless steel base, the adhesion cannot be improved by the commonly used gold plating method on stainless steel. A good gold plating layer is possible. Next, black plating such as black chrome plating, black ruthenium plating, and black rhodium plating generally has extremely poor adhesion to stainless steel, which tends to form an oxide film on the surface, so gold strike plating is usually used as the base. , in the present invention,
By applying gold plating to the entire surface of the decorative member, the gold plating layer acts as an intermediate layer between the stainless steel material and the black plating in the area where the black plating is finally applied, ensuring the adhesion of the black plating. Since the thickness of the gold plating and black plating is within the concave portion, there are few restrictions on wear resistance, so there is no problem as long as the thickness is 0.1 μm or more to stabilize the color tone. On the other hand, since the portions other than the recessed portions are covered with a Ti-based film, a passivation film is likely to be formed, and the adhesion of the gold plating layer is poor. Therefore, when the Ti-based coating is peeled off by etching in the post-process, the gold plating layer in areas other than the recesses is lifted up and can be easily peeled off, and the discoloration caused by the laser processing described above can be removed at the same time.

凹状の文字が施された時計ケースが得られた。(Example 1) FIGS. 1(a) to 1(g) are cross-sectional views of a watch case produced according to the present invention at various manufacturing steps. A watch case 1 made of stainless steel material SUS304 is installed in a vacuum chamber of an ion plating device, the vacuum chamber is evacuated, and then, prior to the process of ion plating the watch case, Ar gas is applied at 10 Pa and a voltage is applied to the substrate. Ion bombardment was performed at 0.5 KV to clean the surface of the watch case. Next, after exhausting the Ar gas and returning the inside of the vacuum chamber to 3 x 10-2 Pa, N2 gas was again introduced as a reactive gas to 6 x 10-2 Pa, and a substrate voltage of 0.1 KV was applied to generate plasma.
At the same time, metallic Ti is heated and evaporated using an electron beam heating method to form a golden TiN coating 2, which is a compound of Ti and N.
．． It was coated with a thickness of 0 μm. FIG. 1(a) is a sectional view of a watch case formed by the above method. Next, as shown in FIG. 1(b), concave characters were marked by laser processing at a predetermined portion at a depth exceeding the thickness of the TiN coating. Therefore, the SUS304 material is exposed on the surface of the laser-processed characters 3. In this laser processing, commercially available Nd:YA
Using a G laser device (wavelength 1.06 μm), output 10
Processing was performed under the conditions of 0 W and a pulse width of 10 ms. Next, as shown in FIG. 1(c), the entire surface of the watch case in the state shown in FIG. 1(b) was coated with a 23K Au-Ni plating layer 4 of 2.0 μm by electroplating. Next, as shown in FIG. 1(d), all parts other than the recesses that will finally be finished in black are masked with organic paint 5, and the mask is baked at 100° C. for 30 minutes. Next, as shown in FIG. 1(e), a black chrome plating layer 6 of 1.0 μm was coated by electroplating. Next, as shown in FIG. 1(f), the watch case in the state of (e) is immersed in a Triclean ultrasonic machine for 10 minutes to completely remove the organic paint 5. Next, the watch case in the state shown in Figure 1(f) was washed with hydrofluoric acid.
TiN was immersed in a 1:1 mixture of nitric acid (at room temperature) for about 1 minute.
Coating 2 was removed by etching. At this time, the Au-Ni plating layer 4 on the TiN film is also lifted up and removed cleanly, and finally the SUS30 as shown in Fig. 1(g)
4 A watch case was obtained in which a predetermined portion of the watch case was provided with concave letters exhibiting two colors: a gold color due to the Au-Ni plating layer and a black appearance due to the black chrome plating layer.

In a method for manufacturing a decorative member that forms a concave pattern or letters in gold and black on the surface of a decorative member made of a material, a Ti-based film is formed on the entire surface of the SUS material by ion plating, and an arbitrary concave pattern is formed by laser processing. and letters are formed, then a gold plating layer is coated by electroplating, then the concave pattern or the part other than the letters to be finally finished in black is masked with organic paint, and then a black plating layer is coated by electroplating. Then, by peeling off the masking film and removing the Ti-based film by etching, it is possible to improve the deterioration of appearance quality and increase in cost, which were the drawbacks of the conventional method, and to create a desired shape such as a complex shape on the surface of the decorative member. It has become possible to form a concave pattern or letters having gold and black colors, and to provide a decorative member with high decorative value with stable quality and at low cost. It can be applied not only to exterior watch parts such as watch dials, hands, and bands, but also to all decorative parts such as eyeglass frames, lighters, tie clips, and accessories.
