拡散を防止するためである。 Therefore, in the manufacturing method of the present invention, the reason why a film made of gold and aluminum is formed on decorative silver, platinum, gold, or an alloy thereof by dry plating is as follows.
This 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. This is to prevent the diffusion of a coating consisting of gold and aluminum into decorative silver, platinum, gold, or their alloys by plating with Cu, Ni, or Mo, which has a slow diffusion rate for gold and aluminum. be.

える。 As is clear from the above description, the manufacturing method of the present invention can be applied to purple decorative materials that are difficult to process into various shapes as decorative items using conventional manufacturing methods. Decorative materials in various shapes of purple or a mixture of purple and other colors can be manufactured by applying a diffusion-preventing base plating to the surface and then forming a coating made of gold and aluminum on the entire or partial surface. Furthermore, the color tone does not change even when heated during brazing or the like, so it can be said to be an epoch-making product that can replace conventional manufacturing methods.
