いていた。 Conventionally, in order to produce the crystal structure pattern of ornaments made of gold or gold alloys, such as gold plates, rings, bracelets, pendants, wristwatch sides and frames, eyeglass frames, necklaces, ties, cufflinks, etc., It was common to perform electrolytic polishing in a cyan bath or chromium oxide bath after baking and purifying the processed product. As a cyanide bath, H 2 O−KCN-based solution or H 2 O−KCN−
A K2CO3 - HAuCl4 bath was used, and a H2O - CH3COOH - Cr2O3 bath was used as the chromium oxide bath.

飾品の製造方法の早期確立が強く望まれていた。 However, both baths are extremely dangerous because they contain harmful substances such as cyanide and chromium, and when the baths become obsolete, they have the disadvantage that they must be treated with special equipment.
On the other hand, there are electrolytic polishing baths that do not contain these harmful substances, such as H 2 O-HCl baths, but they lose surface luster and erase the crystalline texture surface created by annealing, so they are not suitable for use as decorative items. is not desirable. Therefore, we made the crystal fiber surface stand out even more clearly,
It has been strongly desired to develop an electrolytic polishing bath that does not lose its surface luster, and there has been a strong desire to quickly establish a method for manufacturing ornaments having a pattern of gold or gold alloy crystal fibers.
本発明は上記要求に応えんがためになされたも

た装飾品の製造方法である。 The present invention is characterized in that a workpiece made of gold or a gold alloy is annealed and then electrolytically polished in a bath consisting of chloride, phosphoric acid, and water to have a crystal fiber pattern of gold or a gold alloy. This is a method for producing decorative articles, particularly using an electropolishing bath characterized by containing 50 to 300 g of chloride, 50 to 500 ml of phosphoric acid, and residual water.

めである。リン酸と水だけからなる浴では金や金
合金が電解エツチングされない。 In the manufacturing method of the present invention, a processed product made of gold or a gold alloy is used because gold or a gold alloy has a golden color. As a gold alloy,
Au-Ag-Cu alloy, this alloy with Zn, Ni, etc. added, Au-Ni-Cu-Zn alloy, Au-Ag
-Pd alloy, Au-Fe alloy, Au-Ni alloy, Au-
Examples include Cu-Pd alloys. Furthermore, the reason for annealing a workpiece made of gold or a gold alloy is to create a crystalline texture surface on the surface of the decorative item. If the processed textured surface of the processed product remains unchanged, no matter how much electrolytic polishing is performed, a crystalline texture pattern cannot be obtained, and only a matte surface or a mirror-like glossy surface can be obtained. By annealing at an appropriate temperature and time, crystals can precipitate along the grain boundaries to create a crystalline texture surface of a desired size. The atmosphere at this time may be in a vacuum or in the air,
Further, it may be oxidizing, reducing, or neutral. In the present invention, the reason why electrolytic polishing is performed in a bath consisting of chloride, phosphoric acid, and water is to make the crystal fiber surface stand out in a crystal fiber pattern while maintaining surface gloss. Gold and gold alloys are not electrolytically etched in a bath consisting only of phosphoric acid and water.
また塩化物の代わりに塩酸を用いた塩酸−リン
酸−水の浴では、塩素の作用が強すぎ金又は金合

を用いる。好ましい塩化物としては、NaCl，
KCl，CaCl2，MgCl2などがある。本発明におけ
る電解方法としては、交流電圧，直流電圧，交直
併用，パルス電圧などがある。 Furthermore, in a hydrochloric acid-phosphoric acid-water bath in which hydrochloric acid is used instead of chloride, the action of chlorine is too strong and the surface of gold or gold alloy loses its luster. Therefore, it is necessary to have not only chlorine ions that dissolve gold, but also alkali metal ions and alkaline earth metal ions that suppress this action. For this purpose, chloride is used. Preferred chlorides include NaCl,
Examples include KCl, CaCl 2 and MgCl 2 . The electrolysis method in the present invention includes alternating current voltage, direct current voltage, combination of alternating current and direct current, pulsed voltage, and the like.
本発明の浴において、塩化物の範囲を50〜300

く金又は金合金の表面の光沢を失わせてしまい、
500ml／以上では塩素イオンの移動が遅くなり
ムラが生じやすくなり実用的でない。特に800
ml／以上では光沢がなくなつて装飾品としては
使用できない。 In the bath of the present invention, the chloride range is from 50 to 300.
The reason why it is limited to 50g/ or less is that the amount of chlorine ions that dissolve gold or gold alloy is too small, shortening the bath life.If it is more than 300g/, the amount of chlorine ions is too large and the dissolving power becomes too strong. This is because the surface of gold or gold alloy loses its luster. In addition, the range of phosphoric acid was limited to 50 to 500 ml/ml because if it is less than 50 ml/ml, the power to stabilize the bath is weak and the surface of gold or gold alloy loses its luster.
If it is 500 ml or more, the movement of chlorine ions becomes slow and unevenness tends to occur, which is not practical. Especially 800
If it exceeds ml/ml, it will lose its luster and cannot be used as a decorative item.
以下、実施例と従来例について説明する。 Examples and conventional examples will be described below.
