う欠点を有していた。Conventionally, a gold-aluminum alloy, which is made by adding 15 to 30% by weight of aluminum to gold, has been used as a material that can be substituted for jewelry such as diamonds, emeralds, and rubies because it exhibits a bright purple color. By the way, this material was made into an alloy by melting and VF forming gold and aluminum, but this ingot has the disadvantage that it is difficult to process it into various shapes for decorative items because it is difficult to process it plastically. was.
本発明は上記の欠点を解消せんがためになされたもので

ある。The present invention has been made to overcome the above-mentioned drawbacks, and it is an object of the present invention to provide a method for producing decorative materials of various shapes having a purple gold-aluminum coating on the surface.

するようにすることを特徴とするものである。The present invention is characterized in that a base plating for preventing diffusion is applied to decorative silver, platinum, gold, or an alloy thereof, and then a coating consisting of gold and aluminum is formed by plating to give it a purple color. It is something to do.
而して本発明の製造法において、金とアルミニウムから
成る被膜をめっきにて装飾用銀、白金。In the manufacturing method of the present invention, a film made of gold and aluminum is plated with decorative silver or platinum.

防止するためである。The reason why it is formed on gold or its alloys is so that it can be processed into various shapes as decorative items.It is also possible to form a base plating on decorative silver, platinum, gold, or their alloys to prevent diffusion. The reason for this is that heat treatment such as brazing is performed when assembling the final decorative item, but this heat treatment causes a purple coating of gold and aluminum to diffuse into the decorative set, platinum, gold, or their alloys. death,
Since it becomes impossible to obtain the desired film thickness or color tone of the coating consisting of gold and aluminum, it is necessary to roughen and apply a base plating to prevent diffusion of gold and aluminum into decorative silver, platinum, gold, or their alloys. This is to prevent the film from spreading.
次に本発明の製造方法による具体的な装飾用材料の製造
実施例について説明する。Next, specific examples of manufacturing decorative materials using the manufacturing method of the present invention will be described.
