を向上させ且つ硬くするためである。 In the manufacturing method of the present invention, a coating made of gold and aluminum is plated to coat decorative silver, platinum,
The reason why it is formed on gold or its alloy is so that it can be processed into various shapes as ornaments. Furthermore, the reason why a diffusion-preventing undercoating is applied to decorative silver, platinum, gold, or their alloys is that heat treatment such as brazing is performed when assembling the final decorative item. , the purple-colored coating consisting of gold and aluminum will diffuse into platinum, gold, or their alloys, making it impossible to obtain the desired thickness or color tone of the coating consisting of gold and aluminum. The purpose of this is to prevent the diffusion of a coating consisting of gold and aluminum into decorative silver, platinum, gold, or their alloys, and the base plating may be performed using methods such as sputtering, chemical plating, or electroplating. is used. Also, after depositing a coating of gold and aluminum on decorative silver, platinum, gold, or their alloys,
The reason for heat treatment in an oxidizing atmosphere to oxidize the surface of the film made of gold and aluminum is to change the color before heat treatment to reddish-purple, and to change the color of the gold and aluminum coating to reddish-purple.
This is to further improve the corrosion resistance and hardness of the aluminum alloy itself.

言える。 As is clear from the above description, the manufacturing method of the present invention involves applying a diffusion-preventing base plating to the surface of silver, platinum, gold, or their alloys, and then applying a purple coating made of gold and aluminum to the entire surface or part of the surface. By oxidizing the surface of the coating after it is formed by glittering, it is possible to produce various shapes of reddish-purple and decorative materials that are a mixture of reddish-purple and other colors, and the color tone can also be changed by heating such as brazing. Since the process does not change, it can be said to be an epoch-making product that can replace conventional manufacturing methods.
