【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、複合めっきを施した装飾部品に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to decorative parts subjected to composite plating.

装飾的外観を得ていた。Conventionally, decorative parts have been plated with various gold or gold alloys in terms of decorativeness and corrosion resistance. In addition, composite gold plating in which particles of metal oxides and metal nitrides are dispersed in the coating has a satin-like appearance. I was getting .
［発明が解決しようとする課題］

ある。[Problems to be Solved by the Invention] However, conventional gold plating has a characteristically low film hardness and low wear resistance. In other words, 24 in a cyan alkali bath and 24 in a 40 to 70 Hv acidic bath for plating.
120-150Hv for plating on 4, and other gold alloy plating, for example - A used as an exterior finish for boat fishing.
U-Ni (22-23K) alloy plating is about 200Hv.
従って装飾部品特に時計ケースにおいては摩耗しやすく
装飾外観、品質、を同時に満足するには厚付けが必要で
あった。しかしこの場合も厚付けによる密着性の低下、
コスト高という問題がまぬがれ得なかった。Therefore, decorative parts, especially watch cases, are prone to wear and must be made thicker to satisfy both the decorative appearance and quality. However, in this case as well, the adhesion decreases due to the thickness.
The problem of high costs could not be avoided.
また複合金めっきにおいては、分散微粒子により外観が

ろ高くなるという課題を有していた。In addition, in composite gold plating, the appearance becomes matte due to the dispersed fine particles, and functionally it improves wear resistance, but in order to be used as decorative parts, finish gold plating is applied or mechanical polishing is used to obtain a mirror surface. The problem was that the total cost was higher than that of conventional gold plating.

加工を必要としない、くもりのない装飾的外観を得るた
めには、この選択が重要であり粒径が微細で均一なもの
を適用する必要がある。[Function] The dispersed fine particles used in the present invention are ceramic-based hard particles such as metal oxides, metal nitrides, metal carbides, metal borides, etc., and can be applied as long as they are insoluble in the plating solution. It is not limited. However, in order to obtain a clear decorative appearance that does not require secondary processing, this selection is important and it is necessary to use particles with fine and uniform particle size.
分散粒子の粒径が大きくなるにつれ耐摩耗性は向上する
傾向にある反面、外観のくもりも顕著になり仕上げめっ
きとしての適用が困難になる。また逆に小さくなると、
耐摩耗性にほとんど寄与しなくなると同時に、洛中で凝
集し、均一な被膜を得るのが困難になる。従って、粒径
としては００５〜１μが適当であり、この範囲において
、外観、耐摩耗性の両方を満足する複合被膜を得ること
ができる。As the particle size of the dispersed particles increases, the wear resistance tends to improve, but on the other hand, the appearance becomes noticeably cloudy, making it difficult to apply as a final plating. On the other hand, when it becomes smaller,
At the same time, it hardly contributes to wear resistance, and at the same time it aggregates in the air, making it difficult to obtain a uniform coating. Therefore, a suitable particle size is 0.05 to 1 μm, and within this range, a composite coating that satisfies both appearance and wear resistance can be obtained.
また、セラミックス系硬質粒子のほかに自己潤滑性の高
分子化合物を使用することも可能である。In addition to ceramic hard particles, it is also possible to use self-lubricating polymer compounds.
これは、自己潤滑作用を持つ粒子を、被膜中に分散させ
ることで、被膜の表面摩擦係数が低下し、耐摩耗性が向
上するためであり、フッ素樹脂などがこれにあたる。This is because by dispersing particles with self-lubricating properties into the film, the surface friction coefficient of the film is reduced and the wear resistance is improved, such as fluororesin.
これらの微粒子をめっき被膜中に分散させるためには界
面活性剤の添加が重要である。特に粒子径が小さい場合
は分散性を良くし凝集を防止するために添加する。また
、粒子に正電荷を与え、被膜中分散濃度を上げるために
添加される。これらの目的から界面活性剤としては主に
カチオン系のものが適用される。Addition of a surfactant is important in order to disperse these fine particles in the plating film. Particularly when the particle size is small, it is added to improve dispersibility and prevent agglomeration. It is also added to give positive charge to the particles and increase the dispersion concentration in the film. For these purposes, cationic surfactants are mainly used.
本発明に使用される、マトリックス金属である金めつき

のＡｕ−Ｎｉ金合金めっき等が適当である。Various types of gold plating baths, which are matrix metals, used in the present invention can be used, such as 24K plating and gold alloy plating. However, the harder the matrix metal itself, the better the wear resistance when used as a composite coating, and the use of the composite gold plating as a finishing layer. Gold alloy plating etc. are suitable.
〔実 施 例］
以下本発明を、装飾部品の一つである携帯用時計ケース
での実施例に基づき詳細を説明する。[Example] The present invention will be described in detail below based on an example of a portable watch case, which is one of decorative parts.

For each of No. 7, 50 g/1 was added to the Au-Ni alloy plating valley in the same manner as No. 23, and five types of ZrO2Au-Ni composite films were obtained, differing only in the particle size of ZrO2.
また、粒径０５μの各種微粒子（Ｚ ｒ Ｏ２、ＡＪ２

ィルムなイ吏用した。These were subjected to a wear test in comparison with an Au-Ni alloy plating film obtained without adding anything to the plating solution. For the abrasion test, a Suga abrasion tester manufactured by Suga Test Instruments Co., Ltd. was used, and an alumina wrapping film with 9 micron abrasive grains was used as the mating material.
さらには、耐食性、密着性、外観等の基本品質の評価を
行ない第１表及び第２表の結果を得た。Furthermore, basic qualities such as corrosion resistance, adhesion, and appearance were evaluated, and the results shown in Tables 1 and 2 were obtained.
第１表 装飾部品の特性調査結果
第２表 特性調査の評価基準
各特性の確認方法について以下述べる。外観は目視にて
判定し、耐摩耗性は一定膜厚（２μ）を′摩耗するのに
要する往復摩耗回数によって比較した。Table 1 Results of property investigation of decorative parts Table 2 Evaluation criteria for property investigation The method for confirming each property is described below. The appearance was visually judged, and the abrasion resistance was compared by the number of reciprocating abrasions required to abrade a constant film thickness (2μ).
密着性、耐食性は、時計ケースに各めっきを施した後、
それぞれ、密着性は９０°に折り曲げ被膜の剥離の程度
を調べ、耐食性は４０℃の人工汗及び人工海水中に４８
時間半浸せきし、腐蝕及び変色の発生を調べた。Adhesion and corrosion resistance are determined after each plating is applied to the watch case.
Adhesion was determined by bending the film at 90 degrees and examining the degree of peeling, and corrosion resistance was determined by testing 48°C in artificial sweat and artificial seawater at 40°C.
After soaking for half an hour, the occurrence of corrosion and discoloration was examined.
前記ＺｒＯ２複合めっきの実施例において、粒径が大き
くなるにつれ耐摩耗性が２μの範囲においては向上する
ことがわかる。しかしながら１μをこえた場合は、くも
りが発生し外観的に装飾部品として適用できるものでは
なかった。また逆に０．０５μ以下のものでは耐摩耗性
の向上がみられなかった。In the examples of the ZrO2 composite plating, it can be seen that as the particle size increases, the wear resistance improves in the range of 2μ. However, if it exceeds 1μ, cloudiness occurs and the appearance cannot be applied as a decorative part. On the contrary, no improvement in wear resistance was observed when the thickness was less than 0.05 μm.
またＺ ｒ Ｏ２以外の粒子についても同様であり、耐
摩耗性、装飾外観の両方を満たす粒径は００５〜１μの
範囲である。The same applies to particles other than Z r O2, and the particle size that satisfies both wear resistance and decorative appearance is in the range of 0.05 to 1 μm.
粒径の等しい各種微粒子を用いた場合は、若干のばらつ
きがあるものの、特異的に優れるものはなく各微粒子間
の有意差は認められなかったが、いずれの微粒子を用い
た複合被膜も、微粒子を含まない通常の金めつきに比べ
て２倍程度耐摩耗性は向上した。このばらつきは、各粒
子による被膜中分散濃度の差、粒径自体のばらつきなど
に起因するものである。When using various types of fine particles with the same particle size, there was some variation, but none was specifically superior and no significant difference was observed between the fine particles. Compared to normal gold plating that does not contain gold, the wear resistance was improved by about twice as much. This variation is due to differences in the concentration of particles dispersed in the film, variations in particle size itself, and the like.
従って特に１種の粒子に限定されるものではなく種々の
微粒子の適用が可能である。Therefore, it is not limited to one type of particles in particular, and various types of fine particles can be used.
耐食性、密着性に関しては、複合めっき化にょり低下す
ることはな〈従来の金めつきと同等であり問題はなかっ
た。Concerning corrosion resistance and adhesion, there was no decrease due to composite plating (they were equivalent to conventional gold plating and there were no problems).
以上のように、耐摩耗性、密着性、耐食性、装飾外観を
有する複合金めっきを得ることができ、仕上げ二次加工
なしで装飾部品として十分適用でき得るものであった。As described above, a composite gold plating having wear resistance, adhesion, corrosion resistance, and decorative appearance could be obtained, and could be sufficiently applied as decorative parts without secondary finishing processing.
適用にあたっては、携帯用時計ケース、携帯用時計バン
ド、メガネフレーム、クイビン、カフス等の装飾部品全
般に適用可能である。It can be applied to general decorative parts such as portable watch cases, portable watch bands, eyeglass frames, quills, and cufflinks.
