性が悪いなどの欠点を有していた。(Prior Art) Conventionally, gold plating, copper-zinc alloy plating, or copper-tin alloy plating has been used as a plating method to produce a golden color. However, since gold plating uses gold, it is very expensive and prone to scratches, and copper-zinc alloy plating and copper-tin alloy plating have drawbacks such as poor corrosion resistance.

No. 1 is disclosed, and this is an extremely thin layer of Ag and Cu stacked together with the upper layer having a thickness of 100 Å or less. However, Ag and Cu are both metals with poor corrosion resistance, and according to the inventor's tests, they cannot be used as exterior parts unless they are further overcoated with a thin layer of Cr or a clear coat is applied. Moreover, if the Cr is deposited too thick, the appearance will become white like chromium, and if the surface coating disappears,
Ag and Cu discolor quickly. Therefore, this method is difficult to put into practical use. Moreover, the one of JP-A No. 57-116797 has gold plating applied on top of alloy plating of Cu, Zn, and Sn. However, even with this method, when the soft gold plating wears away, the underlying alloy plating is exposed.
Although this alloy plating is gold in color, it is easily discolored and cannot maintain its gold color.

長所を有しているため注目を集めている。 However, titanium nitride (TiN) films made using the dry plating method are attracting attention because they have advantages such as a golden color, very high altitude, low cost, and good corrosion resistance. .

への利用を阻んでいる。 Titanium nitride has poor electrical conductivity, and wet plating does not adhere well using general metal plating methods, so the surface of titanium or titanium nitride must be roughened by blasting or etching with fluoride chemicals. . However, if the surface of TiN is formed by ion plating, the film thickness is about 1 to 2 μm, and the film will disappear if the above-mentioned blasting or engraving is performed. This makes it difficult to perform plating on TiN, which prevents it from being used as a base material even though it has a golden color.

る。(Technical means) In order to achieve the above object, the present invention forms a film of one type of metal selected from nickel, palladium, gold, or silver with a thickness of 1000 to 2000 Å on ion-plated TiN using a dry plating method. A plating layer made of gold, or one or more of gold, platinum, rhodium, palladium, silver, or an alloy thereof and having the same color tone as the TiN layer is formed on the metal plating film by a wet plating method. In addition, this metal plating film is fired at a temperature of 200° C. to 700° C. for 1 minute to 2 hours.

Also, if it is too thick, the appearance will deteriorate and the degree of adhesion will decrease, so the desirable dry plating film thickness is 1000 Å to 2000 Å. Furthermore, Ti

質を高めることができる。 The purpose of the firing treatment is to diffuse heat between the dry plating layer and the wet plating layer on the TiN. There is almost no heat diffusion when the processing temperature is below 200℃, and when the treatment temperature is 700℃
In this case, an oxide film is formed on the surface, which deteriorates the appearance and causes a phenomenon of dulling, which causes functional problems. When plating watch bands and the like in mass production, dozens of sets are plated on one rack, and if the minimum plating thickness is, for example, 0.5μ, the thickness may be close to 2μ due to variation. Although there is a possibility of peeling in thick plating parts, according to the present invention, heat treatment eliminates this risk and improves quality.

がHv2000、Au−Ni22KがHv200〜300である。(Operations and Effects of the Invention) As described above, according to the present invention, wet plating is applied to the hard underlying ion plating layer through the dry plating layer in the same color tone as the ion plating layer. Therefore, even if the wet plating layer on the surface wears out during use, it will not be noticeable because it has the same color tone as the underlying ion plating layer.Moreover, this layer is very hard and has good corrosion resistance, so there is no risk of further wear and corrosion resistance. No problem. The hardness of titanium nitride is Hv2000, and the hardness of Au-Ni22K is Hv200 to 300.
以下本発明の実施例について詳述する。 Examples of the present invention will be described in detail below.

く、指紋も殆んどつかないものであつた。Example 1 A watch band made of SUS304 was made using a conventional method.
Ion plating TiN. After that, Ni was ion-plated for 20 minutes under the conditions of EB power supply of 10 KV, 600 mA, and vacuum degree of 2 × 10 -4 Torr, and the well-known electroplating method was applied to the nickel plating film.
Au-Ni22K was plated to a thickness of 0.5μ. This watch band was then fired at 350°C for 1 hour. The obtained band was 22K gold, so it was slightly brighter than the TiN color, but there was no variation in color tone and there were almost no fingerprints.
これを人工汗液に24時間浸漬したが何の異常も

蝕を起すことがある。しかし本発明によれば焼成
処理により拡散しているためその心配もない。 This was soaked in artificial sweat solution for 24 hours, but no abnormalities were observed. Also, when I tested this band for 6 months on a mobile phone, the gold plating on the corners peeled off, but the gold color of the TiN base remained, so it did not become mottled with gold and stainless steel color like before. I was bored. If the metal plating is about 0.5μ, it will not peel off when bent even without firing, but if the underlying material is Ni, etc., potential difference corrosion may occur. However, according to the present invention, there is no need to worry about this because the particles are diffused by the firing process.
人工汗液組成は次の通りである。 The composition of the artificial sweat fluid is as follows.
Nac1 9.9ｇ／ Na2S9H2O 0.8ｇ／ 28％アンモニア水 0.07ｍ／ 85％乳酸 1.1ｍ／ 蔗 糖 0.2ｇ／ 尿 素 1.7ｇ／ 水全容を１とする。Nac1 9.9g / Na 2 S9H 2 O 0.8g / 28% ammonia water 0.07m / 85% lactic acid 1.1m / Sucrose 0.2g / Urea 1.7g / The total volume of water is 1.
