であるのが現状である。On the other hand, in order to deal with this problem, a known artificial diamond precipitation treatment method has been proposed, namely, Japanese Patent Application Laid-Open No. 58-91100.
The thermionic emission method described in the publication, and
Attempts have also been made to coat the surfaces of the above-mentioned gold and all-alloy ornaments with artificial diamonds using the high-frequency plasma method described in Japanese Patent No. 5117 and the microwave method described in Japanese Patent Application Laid-open No. 110494/1982. However, at present, artificial diamonds do not precipitate on the surfaces of the above-mentioned gold and gold alloy ornaments, and it is virtually impossible to coat them with artificial diamonds.

、Ｔａ、Ｃｒ、Ｖ。Therefore, from the above-mentioned viewpoint, the present inventors focused on pure gold and gold alloys used in the manufacture of the above-mentioned ornaments in order to develop gold alloy ornaments that can be coated with artificial diamonds. As a result of research, we found that these pure gold and gold alloys contain Hf, Zr, and Ti as alloy components.

である。Contains one or more of Zr, Ti, Ta, Cr, V, Nb, Mo, and W: 1 to 20%, and further contains Ag, Pd, Cu, and Ni as necessary. A gold alloy made by coating artificial diamond on the surface of a base made of a gold alloy containing one or more of the following: 1 to 40%, with the remainder consisting of Au and unavoidable impurities. It is a characteristic of ornaments.

。The content of Mo and W was set at 1 to 20% because if the content is less than 1%, artificial diamond cannot be coated with good adhesion as described above. This is because if the gold alloy exceeds the color tone, which has high decorative and aesthetic value, it will not only lose its color tone, but also have poor castability and workability. Change the color tone to

This is based on the reason that in addition to the damage, the processability also decreases.

である。In addition, the thermionic emission method, which is known as the artificial diamond precipitation treatment method, uses a reaction mixture that opens at an upper position in a vertical reaction vessel 1 made of quartz, as shown in a schematic cross-sectional view in FIG. A reaction mixture gas mainly composed of hydrocarbons and hydrogen, which flows in through the gas introduction pipe 2, is supported on a filament 3 made of metal tungsten as a thermionic emitting material, for example, and a base plate 4, which are arranged below the gas introduction pipe 2. During this time, the atmospheric pressure in the reaction vessel 1 was maintained at 0.1 to 30 (lLorr), and the filament 3 was heated to 1500 to 2500°C.
The reaction mixture gas is activated by heating, and the surface of the substrate disposed below at a predetermined interval is heated to a temperature within the range of 300 to 1300°C, and the reaction is carried out for a predetermined time in this state. This is a method in which diamond is precipitated on the surface of 5.
The method described in Publication No. 00 is a method corresponding to this method.

れに相当するものである。In addition, in the above-mentioned high-frequency plasma method, as shown in the schematic cross-sectional view in FIG. A reaction mixture gas mainly composed of hydrocarbons and hydrogen is introduced from the gas introduction pipe 2, and exhausted from the other side of the reaction vessel 1. During this time, the atmospheric pressure within the reaction vessel 1 is maintained at several LOrr to several tens of LOrr. At the same time, a condition of, for example, a frequency of 13.56 MIIz 1 output 500 W is added to the high frequency coil 6 provided on the outer periphery of the central part of the reaction vessel 1 to induce plasma discharge around the base 5 in the reaction vessel 1, and this plasma This is a method in which diamond is precipitated and formed on the surface of the substrate by heating and activating the reaction mixture gas and raising the substrate surface temperature by electric discharge, and carrying out the reaction for a predetermined period of time in this state. The method described in the official gazette corresponds to this.

方法がこれに相当する方法である。Furthermore, in the microwave method, as similarly shown in the schematic cross-sectional view in FIG. A reaction mixture gas consisting mainly of hydrocarbons and hydrogen is introduced from the mixed gas introduction pipe 2, while being exhausted from the lower part of the reaction vessel 1, during which time the atmospheric pressure inside the reaction vessel is kept at 0.1.
For example, 24 torr was supplied through the waveguide 7 provided on the outer periphery of the central part of the reaction vessel 1 while maintaining the pressure at ~300 torr.
Plunger 8 for plasma adjustment using 50MHz microwave
A plasma discharge is generated around the substrate 5 in the reaction vessel 1, and this plasma discharge heats and activates the reaction mixture gas and increases the substrate surface temperature, and the reaction is carried out for a predetermined time in this state. This is a method in which diamond is precipitated and formed on the surface of a substrate by tightening the substrate.For example, the method described in JP-A-58-110494 is an equivalent method.
