Description

Ornament (CN)

Technical Field

The present patent application relates to an ornament for jewelry and watches, including rings, necklaces, earrings, bracelets and the like.

Background

Korean patent laid-open publication No. 1020160110610 (patent document 1) discloses a jewelry material molded using a first metal piece of a first color and a second metal piece of a second color different from the first color, the surface of the jewelry material having a gradual color. In casting a jewelry material, a first metal block and a second metal block are set in a cylindrical mold. The first metal block has a cross section that gradually decreases toward the die entrance, and the second metal block has a cross section that gradually increases toward the die entrance. The induction coil forms a molten layer along the cross section of the first metal block and the second metal block. As the flat molten layer gradually moves toward the mold entrance, the ratio of the first metal block and the second metal block in the molten layer changes, thereby achieving a color gradient.

In the method of manufacturing a jewelry material of patent document 1, a flat molten layer is formed along a horizontal plane. Although magnetic force lines act on the molten layer, convection in the horizontal direction hardly occurs in the molten layer. Since the molten layer is flat along the horizontal plane, color unevenness is likely to occur in the molten layer. As a result, it is difficult to achieve a desired color arrangement in the final material.

Therefore, there is a need to provide a decoration that achieves a color gradation through a carefully calculated arrangement.

Disclosure of Invention

In a first aspect of the present patent application, there is provided a decorative article comprising an alloy body of gold formed by metal diffusion and having a surface exhibiting a gradual color change.

In a second aspect of the present patent application, the alloy body comprises a plurality of gold alloys having different colors.

In a third aspect of the present application, there is provided a method of manufacturing an alloy body for ornaments, comprising: stacking a plurality of alloy materials having different colors; heating the materials, mixing the gold alloy at an interface between the materials by metal diffusion, and forming a gradient of the materials across the interface; and processing the material block, and adjusting the gold alloy body which is formed by metal diffusion and has a gradually changed color on the surface.

In the first aspect, since alloys of gold (hereinafter referred to as "gold alloys") are all similar in color, when gold alloys of different colors are combined by metal diffusion, color mixing by metal diffusion is good at the interface between the gold alloys. The interface between the gold alloy disappears. Away from the interface, the metal diffusion is reduced, thus forming a gradual change in the material mixing across the interface. So that the surface of the alloy body exhibits a beautiful color gradation gradually changing from one color to another. The metal diffusion is achieved by a solid metal, so that the interface between the gold alloys can be placed at a desired position according to the shape of the solid. This makes it possible to provide a decoration that achieves a gradation of color by a carefully calculated arrangement.

In a second aspect, a gold alloy provides two or more starting colors when forming a gradient. Gradually changing from one color to another across the interface. Therefore, a beautiful color gradation is exhibited on the surface of the alloy body. Here, the decoration may include a metal body of gold, palladium, or platinum bonded to the alloy body by metal diffusion. If the color of the joined gold alloy is similar to that of gold, palladium or platinum, the gold alloy and the metal body of different colors are joined by metal diffusion, and the colors are mixed well by metal diffusion at the interface between the gold alloy and the metal body. The interface between the gold alloy and the metal body disappears. As described above, a gradual change of material is formed.

In the third aspect, since the alloys of gold are all similar in color, when the gold alloys of different colors are combined by metal diffusion, the colors are mixed well at the interface between the gold alloys by metal diffusion. The interface between the gold alloy disappears. Away from the interface, the metal diffusion is reduced, thus forming a gradual transition across the interface. So that the surface of the alloy body exhibits a beautiful color gradation gradually changing from one color to another. The metal diffusion is achieved by a solid metal, so that the interface between the gold alloys can be placed at a desired position according to the shape of the solid.

Detailed Description

Hereinafter, embodiments of the present patent application are described with reference to the drawings.

Fig. 1 is a schematic view of a necklace as an ornament as one embodiment of the present patent application. The necklace 11 comprises a chain 12 wound around a neck and a pendant 13 combined with the chain 12. For example, the pendant 13 includes an alloy body 13a of gold formed by metal diffusion and having a surface exhibiting a gradual color change. The surface of the alloy body 13a is embedded with a plurality of diamond grains 13 b.

The alloy body 13a contains a plurality of gold alloys having different colors. For example, Gold alloys may include platinum (WhiteGold), Gold (Yellow Gold), Rose Gold (Rose Gold), Red Gold (Red Gold), Pink Gold (Pink Gold), Green Gold (Green Gold), Blue Gold (Blue Gold), Purple Gold (Purple Gold), Gray Gold (Gray Gold), and others. For example, Platinum consists of 75 weight percent gold and 25 weight percent Palladium (Palladium) or Platinum (Platinum). For example, gold consists of 75 weight percent gold, 12.5 weight percent copper, and 12.5 weight percent silver. For example, rose gold consists of 75 weight percent gold, 22.25 weight percent copper, and 2.75 weight percent silver. For example, red gold consists of 75 weight percent gold and 25 weight percent copper. Alternatively, for example, red gold may be composed of 50 weight percent gold and 50 weight percent copper. For example, pink gold consists of 75 weight percent gold, 20 weight percent copper, and 5 weight percent silver. Alternatively, for example, pink gold may also consist of 75 weight percent gold, 19 weight percent copper, 4 weight percent silver, and 2 weight percent palladium. For example, the green gold consists of 75 weight percent gold, 6 weight percent silver, 10 weight percent copper, and 9 weight percent zinc. Alternatively, for example, the gold green may also consist of 75 weight percent gold, 20 weight percent silver, and 5 weight percent copper. For example, blue gold consists of 75 weight percent gold and 25 weight percent iron. For example, violet gold consists of 80 weight percent gold and 20 weight percent aluminum. For example, gray gold consists of 75 weight percent gold, 17 weight percent iron, and 8 weight percent copper. For example, the color of gold alloy changes depending on the weight ratio of gold, copper, and silver (palladium may be added here). However, the weight ratios of the components are merely examples. Here, the alloy body may contain any one or more of gold, palladium, and platinum bonded to the gold alloy by metal diffusion.

Since the alloys of gold are all similar in color, when gold alloys of different colors are combined by a metal diffusion phase, the color mixing by metal diffusion is good at the interface between the gold alloys. The interface between the gold alloy disappears. Away from the interface, the metal diffusion is reduced, thus forming a gradual transition across the interface. So that the surface of the alloy body 13a exhibits a beautiful color gradation gradually changing from one color to another color. The metal diffusion is achieved by a solid metal, so that the interface between the gold alloys can be placed at a desired position according to the shape of the solid. This makes it possible to provide a decoration that achieves a gradation of color by a carefully calculated arrangement.

Next, a method for producing the alloy 13a will be described. As shown in fig. 2A, a plurality of

materials

14a, 14b, 14c, 14d, 14e of different colors are prepared. The materials 14a to 14e are formed into plate materials. Each of the materials 14a to 14e is made of gold alloy such as K22 gold, K20 gold, K18 gold, K14 gold, or the like. In addition to these gold alloy plates, a single gold (K24 gold) plate, a single palladium plate, or a single platinum plate may be used. However, the materials are not limited to five. At least adjacent materials 14 a-14 e have similar colors.

The sheets are stacked in sequence. The stacking order is determined according to the final gradient hue. Gold alloys have a unique color depending on the weight ratio of gold, copper, and silver (palladium may be added here). In the final gradient color tone, the position of the color can be adjusted at the interface position between the adjacent boards. The interface position can be adjusted by the thickness of the sheet material. At this time, since the mono-palladium plate or the mono-platinum plate is silver (white), it is preferably stacked on the platinum or the grey gold. So that the single palladium plate or the single platinum plate is well mixed with the gold alloy plate. The interface disappears and a color gradient is formed.

As shown in fig. 2B, pressure is applied to the stacked body 15 of stacked sheets. The pressure is set to an appropriate value according to the material and thickness of the plate materials contained in the stacked body 15 and the number of the plate materials. For example, the pressure may be set at 39kN/cm²～981kN/cm²In the meantime. The adhesion of the materials 14 a-14 e may be improved at the interface between the sheets depending on the pressure applied.

The stack 15 is then heated. Similarly, the heating temperature is set to be appropriate depending on the material and thickness of the plate material included in the stacked body 15 and the number of plate materials. For example, the heating temperature may be set between 700 degrees celsius and 1800 degrees celsius. As the heating temperature, a temperature lower than the melting point of the material is sufficient. By heating, thermal diffusion proceeds at the interfaces between the materials 14a to 14 e.

The heating duration is also set to be appropriate depending on the material and thickness of the plate material contained in the stacked body 15 and the number of plate materials. For example, the duration of heating may be set between 60 minutes and 18 hours. The stack 15 is integrated by the pressurization and heating treatment.

Thereby forming a billet 16 as shown in fig. 3. In the billet 16, metal diffusion occurs at the interface between the sheets. And a gradual transition is formed across the interface. As can be seen from fig. 3, at the cut surface 16a of the billet 16, the interface between the sheets disappears. The surface of the billet 16 (including the cut surface 16a) exhibits a gradual color change.

The square billet 16 is adjusted to a specific shape by a press working or a forging working. Thereafter, the surface of the finished square billet 16 is finished. This forms a gold alloy body 13 a. Based on the alloy body 13a thus obtained, the pendant 13 was produced.

Fig. 4 is a schematic view of another embodiment of a ring as an ornamental article. The ring 21 has an annular alloy body 21a formed in accordance with the thickness of a finger. For example, the alloy body 21a is formed by metal diffusion and the surface exhibits a color gradation. The composition of the alloy body 21a is the same as that of the alloy body 13a described above.

Fig. 5 is a schematic view of an earring as a decoration according to still another embodiment. The earring 22 has a metal fitting 23 fixed to the ear by elastic force, and a rod-like alloy body 24 connected to a protruding ring 23a of the metal fitting 23. For example, the alloy body 24 is formed by metal diffusion and the surface exhibits a color gradient. The composition of the alloy body 24 is the same as that of the alloy body 13a described above.

Fig. 6 is a schematic view of a bracelet as an ornament of yet another embodiment. The bracelet 25 has an annular alloy body 25a shaped according to the thickness of the wrist. For example, the alloy body 25a is formed by metal diffusion and the surface exhibits a color gradation. The composition of the alloy body 25a is the same as that of the alloy body 13a described above.

The alloy body similar to the alloy body 13a may be used for accessories such as tie-clips and hair clips, and may be used for a bezel (bezel), a band (band), or a case (case) of a wristwatch as one of the accessories. The alloy body similar to the alloy body 13a can also be used for ornaments such as ornaments (ornaments) and metal fittings to be mounted on bags, purses, belts, and the like.
