(Industrial Application Field) The present invention relates to a composite material for decorative items, particularly a composite material for decorative items such as eyeglass frames, tie pins, and watch bands, which has spring properties, is lightweight, and has excellent brazing properties. Regarding the manufacturing method. (Prior Art and its Problems) Recently, there has been a demand for materials for decorative articles that are lightweight and have excellent spring characteristics in order to increase activity and enhance the sense of decoration in various decorative articles. On the other hand, precious metals used as materials for decorative articles have poor spring properties and are also disadvantageous in terms of weight reduction. Therefore, research and development efforts are underway to compensate for these shortcomings, and the application of composite materials made of Ti or Ti alloys clad with precious metals to ornaments is being considered. By the way, for decorative items, after assembling parts with complex shapes,
In many cases, the final product is made by brazing, so it is essential for materials for decorative items to have excellent brazing properties.In particular, materials for decorative items such as eyeglass frames, tie clips, and hairpins are soldered with wax. Not only is it required to have excellent attachment properties, but it is also required to have excellent spring properties. However, the conventional composite material 1 for decorative items shown in Fig. 3
Because of its light weight, Ti or Ti alloy core material 2
Carat gold, e.g. Au83.4% by weight, directly on the outer periphery of the
20-karat gold jacket metal 3 with Ag8.0wt% and Cu8.6wt%
When this is processed into the rim wire 4 for eyeglass frames and brazed as shown in Figure 4, it will be exposed to high temperatures of 600 to 900 degrees Celsius during brazing.
On the brazed portion 5 side, Au in the outer sheath metal 3 forms a very brittle intermetallic compound 6 with Ti. As a result, this intermetallic compound 6 forms the outer shell metal 3 and the core material 2.
It peels off and becomes unusable. Further, the composite material 1 for decorative items has a metal outer cover 3.
20K gold has poor spring properties, and Ti, which is the core material 2, also has poor spring properties. In order to improve the spring characteristics of Ti,
Various Ti alloys have been developed that are alloyed with various metals, but these lack the workability required for materials for decorative items. (Object of the Invention) The present invention has been made to solve the above problems, and provides a composite material for decorative items that is lightweight, has excellent brazing properties, and has good workability and spring properties, and a method for manufacturing the same. The purpose is to (Structure of the Invention) The composite material for decorative articles of the present invention is composed of Ni containing 5 to 60% by weight of Cu in Ti or Ti alloy plated with Mo.
It is characterized in that an alloy is clad as an intermediate material, and a noble metal alloy is further clad. The method for producing a composite material for decorative articles of the present invention includes Ti
Or apply Mo plating to the outer peripheral surface of Ti alloy material,
Au plating on the outer and inner circumferential surfaces of Ni alloy pipes containing 5 to 60% Cu, and on the inner circumferential surfaces of precious metal alloy pipes.
After applying Ag plating or Ni plating, Ti or Ti
This method is characterized by fitting a Ni alloy pipe into the alloy, then fitting a noble metal alloy pipe into the alloy, and then performing plastic working such as extrusion or drawing to form a cladding. In the composite material for ornaments with the above structure, using Ti or Ti alloy with Mo plating is as follows:
This is to obtain a composite material that does not have any adverse effects during brazing and has high bonding strength. Also Ti
Alternatively, the Ni--Cu alloy is clad between the Ti alloy and the noble metal alloy in order to prevent the formation of intermetallic compounds due to diffusion of Ti and the noble metal alloy during brazing, and to provide sufficient springiness. Furthermore, the Cu content of Ni-Cu alloy is increased to 5 to 60% by weight.
The reason for this limitation is that if it is less than 5% by weight, the spring properties will be insufficient, and if it exceeds 60% by weight, embrittlement will occur due to diffusion with Ti. The thickness of Ti or Ti alloy, intermediate material, and precious metal alloy is 10 to 50:3 to maintain springiness and lightness.
20:1 is desirable. Furthermore, in the above method for manufacturing a composite material for decorative items, Mo plating is applied to the outer circumferential surface of Ti or Ti alloy, Au plating is applied to the outer circumferential surface and inner circumferential surface of Ni alloy pipe, and the inner circumferential surface of noble metal alloy pipe, The reason for applying Ag plating or Ni plating is that oxidation during the manufacturing process is prevented and the process is simplified. (Example) A specific example of the present invention will be described together with a conventional example. The decorative composite material 10 shown in FIG.
2.73mm Ti is used as the core material 11, and 0.10mm thick Ti is used as the core material 11.
A Ni-Cu 10% alloy was clad as the intermediate material 12, and an Ag-Cu alloy with a thickness of 0.034 mm and an outer diameter of 3.0 mm was used.
A 30% by weight Pd alloy is clad as the jacket metal 13, and the thickness ratio thereof is 40:3:1. This was manufactured by applying 5μ of Mo plating to the outer circumferential surface of a Ti bar with a diameter of 45.4 mm by sputtering, and applying Ni to the outer and inner circumferential surfaces of a Ni-Cu 10% alloy pipe with an inner diameter of 45.5 mm and an outer diameter of 49.0 mm. Ag-Pd 30% by weight with 10μ plating, inner diameter 49.1mm, outer diameter 50.2mm
After applying 10μ Ni plating to the inner peripheral surface of the alloy pipe, Ti
A 10% by weight Ni-Cu alloy pipe is fitted into the bar material, and a 30% by weight Ag-Pd alloy pipe is fitted into this, then extrusion is performed to clad these, and further drawing is performed to obtain the above dimensions. This is what was done. The decorative composite material 10 shown in FIG.
2.32mm Ti is used as the core material 11, and 0.34mm thick Ti is used as the core material 11.
Ni-Cu 35% by weight alloy is clad as the intermediate material 12, and 20-karat gold with a thickness of 0.034 mm and an outer diameter of 3.07 mm is clad as the outer sheath metal 13, with a thickness ratio of 34:10:1. It is something. This was manufactured by sputtering a Ti bar with a diameter of 37.7 mm and applying Mo plating of 5 μm to the outer circumferential surface.
49.0mm Ni-Cu35wt% alloy pipe with 10μ Ni plating on the outer and inner surfaces, inner diameter 49.1mm, outer diameter
After applying 5μ of Ni plating to the inner circumferential surface of a 50.1 mm 20-karat gold pipe, a Ni-Cu 35% by weight alloy pipe was fitted onto the Ti bar, a K20 alloy pipe was fitted into this, and then extruded. These were then clad and then drawn to the dimensions described above. On the other hand, the conventional composite material 1 for decorative items as shown in FIG.
In one example, Ti with a diameter of 2.97 mm is used as the core material 2, and 20-karat gold with a thickness of 0.015 mm and an outer diameter of 3.0 mm is clad as the outer sheath metal 3, with a thickness ratio of 105:1. It is something. The production of this is 49.5 in diameter.
After fitting a 20-karat gold pipe with an inner diameter of 49.6 mm and an outer diameter of 50.1 mm into a Ti bar with a diameter of
Subsequently, drawing was performed to obtain the dimensions described above. The specific gravity and tensile strength in the annealed state of the composite materials for decorations of the first example, the second example, and the conventional example manufactured as described above were measured, and the decorations of the first example and the second example were further measured. A composite material for accessories is processed into a rim wire 15 for an eyeglass frame as shown in FIG. 2 and brazed together, and a conventional composite material for an ornament is processed into a rim wire 4 for an eyeglass frame as shown in FIG. After brazing, the strength of these brazed parts was measured and the quality was inspected, and the results shown in the table below were obtained.
