る。 In the manufacturing method of the present invention, gold and aluminum are dry plated in an oxidizing atmosphere to produce decorative silver,
The reason for adhering to platinum, gold, or their alloys is that they can be processed into various shapes as ornaments, and the simple purple alloy coating consisting of gold and aluminum is oxidized during manufacturing, changing the simple purple color to a reddish-purple color. This is to improve corrosion resistance and make it harder than the alloy coating itself consisting of gold and aluminum. Furthermore, the reason why a diffusion-preventing base plating 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. , a coating consisting of gold, aluminum, and oxygen that exhibits a reddish-purple color will diffuse into platinum, gold, or their alloys, making it impossible to obtain the desired film thickness or color tone. This is to prevent the coating from diffusing into decorative silver, platinum, gold, or alloys thereof.
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.

A sputtering device was used to coat the plate with Ni to a thickness of 2μ, and then gold-aluminum was added on top of that.
10 -3 Torr using a 22 wt% alloy target
When a 0.2 mm thick film was deposited by sputtering in an Ar + O 2 atmosphere, the surface of the platinum-palladium 10 wt% plate exhibited a bright reddish-purple color due to the oxidation of the gold-aluminum 22 wt% alloy. The Bitkers hardness increased from 75 to 250 and was hardened. Furthermore, this platinum-palladium 10% by weight plate
Even after heat treatment at 600°C for 10 minutes in a vacuum, the bright purple color did not change.
