本発明は、ステンレスを母材金属材料とする装身具用複
合材料に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite material for jewelry using stainless steel as a base metal material.
一般にステンレスは、耐食性に優れていることから時計
バンド、眼鏡フレーム等の装身具用材料として広く用い
られ、その中でも特にＳＵＳ３０４が主として用いられ
ている。In general, stainless steel is widely used as a material for jewelry such as watch bands and eyeglass frames because of its excellent corrosion resistance, and among these, SUS304 is mainly used.
ところで近時、このＳＵＳ３０４に金を主成分とする金
合金を張り合せた複合材料が装身具用材料として使用さ
れているが、この複合材料の母材であるＳＵＳ３０４は
加工硬化率が高いので、焼なましする必要がある。Recently, a composite material made by laminating SUS304 with a gold alloy containing gold as a main component has been used as a material for jewelry, but the base material of this composite material, SUS304, has a high work hardening rate, so it cannot be baked. I need to smooth it out.
然し乍ら、この複合材料を焼なましするには、金を主成
分とする金合金が溶けない１０００℃以下の温度で行な
わなければならず、その結果母材であるＳＵＳ３０４中
に炭化物が析出し、耐食性が著しく低下した状態のまま
装身具用複合材料として使用していた。However, in order to anneal this composite material, it must be done at a temperature of 1000°C or lower, where the gold alloy, which is mainly composed of gold, does not melt, and as a result, carbides precipitate in the base material SUS304. It was used as a composite material for jewelry with significantly reduced corrosion resistance.
本発明はかかる実状に鑑みてなされたものであり、６０

張りの装身具用複合材料を提供せんとするものである。The present invention has been made in view of such circumstances, and is
It is an object of the present invention to provide a composite material for jewelry coated with a gold alloy, which causes little carbide precipitation in the base metal material and does not impair corrosion resistance even when annealing is performed at 0 to 1000°C.

る。The composite material for accessories according to the present invention has a weight ratio of Cr15 to 2.
0%, N110-16%, M00.5-3%, Co, 0
It is characterized in that a gold alloy containing gold as a main component is laminated to a base metal material of 5% or less and the balance being Fe.
然して本発明の装身具用複合材料に於いて、上述の如く
母材金属材料の成分組成を限定した理由について説明す
ると、Ｃｒについては１５％未満では耐食性が低下して
しまい、２０％を超えると材料製作途中に於ける焼鈍工
程に於いて酸化され易くなり、母材金属材料に金合金を
複合することが困難となるからである。However, in the composite material for accessories of the present invention, to explain the reason why the component composition of the base metal material is limited as described above, if Cr is less than 15%, the corrosion resistance will decrease, and if it exceeds 20%, the material will deteriorate. This is because it becomes easily oxidized during the annealing process during manufacturing, making it difficult to combine the gold alloy with the base metal material.
またＮｉについては、１０％未満では加工硬化率が高く

食が生じたが、本発明の複合材料から製作した時計バン
ドには全々腐食は生ぜず耐汗性に優れたものであつた。Regarding Ni, if it is less than 10%, the work hardening rate becomes high and it becomes difficult to process, and if it exceeds 16%, it becomes expensive. Furthermore, the addition of Mo is for improving acid resistance, and if it is less than 0.5%, the effect is weak, and if it exceeds 3%, no further improvement effect can be obtained. Also, setting C to 0.05% or less means 0
．． This is because if it exceeds 0.05%, the work hardening rate will increase, making it difficult to process, and carbides will increase, making it difficult to maintain corrosion resistance. 17%Cr-12%Ni-O,
H gold (58.5% Au-6
%Ag-29.5%Cu-Zn) of the present invention and a conventional composite material in which H gold having the same composition as above was laminated to the base metal of SUS304 were heated at 850°C.
After annealing, the watch band was processed into a watch band and used for one year. While the watch band made from the conventional composite material had intergranular corrosion, the watch band made from the composite material of the present invention showed no signs of intergranular corrosion. No corrosion occurred and it had excellent sweat resistance.

金を張り合せた複合材料にとつて代わることのできる装
身具用材料といえる。The composite material for jewelry of the present invention, in which a gold alloy containing gold as a main component is laminated to a base metal material having the above-mentioned composition, is annealed at 600 to 1000°C at which the gold alloy does not melt. Because it has very little carbide precipitation and excellent corrosion resistance, it can be said to be a material for jewelry that can replace the conventional composite material made of SUS3O4 laminated with a gold alloy whose main component is gold.
