Abstract
The utility model provides a silver-cast gold handicraft, including the base member of silver material preparation, with the electroforming be in the cladding material that the base member surface was made by the gold material the base member with the electroforming has the metal protection layer between the cladding material. The utility model discloses at the silver surface of silver-colored cast gold handicraft other strong metal levels of stability of electroforming one deck earlier, can avoid the infiltration after each other contact between gold and the silver, can avoid the original colour of handicraft to change. Meanwhile, the contact between the surface of the silver matrix and air can be avoided, silver is prevented from being oxidized and discolored, and the service life of the silver-cast gold handicraft is greatly prolonged.
Description
Technical Field
The utility model relates to an handicraft preparation field especially provides one kind and can avoid silver in use to discolour and the unstable silver gold casting handicraft of effect.
Background
As a solid silver or gold product, if the mass is larger, the corresponding price can be increased, therefore, the prior hollow precious ornaments meet the aesthetic requirements and reduce the price. At present, some silver-cast gold ornaments formed by casting a layer of gold on the surface of the silver ornaments can improve the display effect without spending large cost, and have a large market.
However, when the silver ornament is directly electroformed with gold, if the electroformed gold is thinner, the gold and silver ions will interpenetrate over time, which results in the discoloration of the surface effect of the ornament and the reduction of the display effect of the ornament. In addition, because the noble metal mixed liquid used in electroforming contains substances such as acid, salt and the like, the color change phenomenon such as erythema and the like is easy to occur when the silver gold casting ornament is worn or placed for a period of time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a silver cast gold handicraft which can avoid the color change of silver in use and has unstable effect.
Particularly, the utility model provides a silver-cast gold handicraft, including the base member of silver material preparation, and the electroforming is in the cladding material that the base member surface was made by the gold material the base member with the electroforming has the metal protection layer between the cladding material.
In one embodiment of the present invention, the thickness of the metal protection layer is 0.05 to 1 μm.
In one embodiment of the present invention, the metal used in the metal protective layer is one of palladium, nickel, rhodium, or chromium.
In one embodiment of the present invention, the thickness of the plating layer is 0.01 to 0.2 mm.
In one embodiment of the present invention, the surface of the substrate is patterned.
The utility model discloses at the silver surface of silver-colored cast gold handicraft other strong metal levels of stability of electroforming one deck earlier, can avoid the infiltration after each other contact between gold and the silver, can avoid the original colour of handicraft to change. Meanwhile, the contact between the surface of the silver matrix and air can be avoided, silver is prevented from being oxidized and discolored, and the service life of the silver-cast gold handicraft is greatly prolonged.
Drawings
Fig. 1 is a schematic sectional view of a plating layer of a silver-cast gold handicraft according to an embodiment of the present invention.
Detailed Description
As shown in fig. 1, one embodiment of the present invention discloses a silver-cast gold handicraft, which comprises a substrate 1 made of silver material, and a plating layer 2 made of gold material and electroformed on the surface of the substrate 1, wherein a metal protection layer 3 is electroformed between the substrate 1 and the plating layer 2. The substrate 1 can be in any form of ornamental article, such as a bracelet, a longevity lock, a necklace, etc. Wherein, various patterns can be made on the surface of the substrate 1, and the thickness of the plating layer 2 made of gold can be 0.01-0.2 mm. The method of electroforming gold on the surface of the silver base 1 can be realized by the existing method, and similarly, the method of electroforming the metal protective layer 3 on the surface of the silver base 1 can also be realized by the method in the prior art.
A layer of other metal protective layers with strong stability is electroformed on the surface of the silver matrix 1, so that the permeation of gold and silver after mutual contact can be avoided, and the original color of the artware can be prevented from changing. Meanwhile, the contact between the surface of the silver matrix and air can be avoided, silver is prevented from being oxidized and discolored, and the service life of the silver-cast gold handicraft is greatly prolonged.
In the present embodiment, the thickness of the metal protection layer 3 may be between 0.05 and 1 μm. Specifically, the metal used for the metal protection layer 3 may be any one of palladium, nickel, rhodium, and chromium, and palladium may be preferably used as a material for forming the metal protection layer 3, and palladium has high stability, does not permeate silver or gold, and prevents gold and silver from permeating. In addition, the palladium has strong adhesive force, so that the electroforming bonding force of the silver and the gold is stronger, the palladium is non-toxic and harmless, the processing link is environment-friendly, the palladium also belongs to rare metal, and the noble metal property of the whole product cannot be reduced.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
