Abstract

(57) [Summary] [Purpose] The present invention is made of pure gold (K24) or pure platinum (Pt1).
000) etc. to strengthen the surface hardness of precious metal ornaments, prevent wear and scratches, and provide precious metal ornaments that maintain their quality for a long period of time. To do. [Constitution] This invention is pure gold (K24) or pure platinum (Pt1
000) and other precious metal ornaments made of precious metal on the outer surface of the same material, such as pure gold or pure platinum, by forming a plating layer by electrolysis, electroless, IP, vapor deposition, etc. A hardened structure of a precious metal ornament, which is characterized by enhancing the surface hardness without deteriorating the purity of the precious metal of the ornament.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a hardened structure for precious metal ornaments.

[0002]

[Prior art]

 Conventionally, various precious metal ornaments made of precious metals such as pure gold (K24) or pure platinum (Pt1000) (necklaces, bracelets, rings, earrings, wristwatches, pocket watches, lighters, key chains, etc.) They have made portable items, tableware, various figurines, etc.).

[0003]

[Problems to be solved by the device]

 However, the precious metal ornaments had the problem that they were easily worn or scratched due to the soft material of both pure gold and pure platinum.

[0004]

[Means for Solving the Problems]

 The present invention uses various types of precious metal ornaments made of precious metals such as pure gold (K24) or pure platinum (Pt1000) for the electrolysis and electroless electrolysis using the same material as pure gold or pure platinum. , IP (ion plating), vapor deposition, etc. to form a plating layer to enhance the surface hardness without deteriorating the purity of the precious metal of the decorative article, and to solve such problems. .

[0005]

[Action]

 A precious metal ornament is formed from a precious metal material such as pure gold (K24) or pure platinum (Pt1000), and the outer surface of the ornament is plated with pure gold or pure platinum of the same material by an electrolytic method or the like. . The outer surface of the decorative article is sequentially covered with the plating layer, and the hardness of the outer surface of the precious metal decorative article increases about three times or more due to the hydrogen gas in the plating layer and the stress generated in the plating layer. .

[0006]

【Example】

 The ring 1 is formed using a pure gold (K24) material, and the entire outer surface of the ring 1 is electrolytically plated with pure gold (K24) of the same material. The outer surface of the ring 1 is covered with the plating layers 2a ... 2x that are successively formed, and the hardness increases due to the stress generated between the plating layers 2a ... 2x and the presence of hydrogen gas mixed in the layers. Will be done.

[0007]

[Effect of device]

 As described above, by plating the outer surface of a precious metal ornament made of pure gold (K24) or pure platinum (Pt1000) with pure gold or pure platinum of the same material, the hardness of the outer surface of the ornament is improved. By increasing the value to about 3 times or more, there is an effect that it is possible to eliminate the defect that the ornaments made of pure gold or pure platinum, which are caused by the soft outer surface, are easily worn or scratched.

Moreover, since plating is performed using pure gold or pure platinum of the same material as pure gold or pure platinum, there is an effect that the purity and quality of pure gold or pure platinum are not deteriorated.

The ornaments made of pure gold or pure platinum have the effect of keeping the quality as long as possible because wear is suppressed as much as possible and scratches are less likely to occur.
