本発明は、素地を荒らすことなくＰＶＤ被膜のみを剥離
することのできる装飾品被膜の剥離方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for removing decorative coatings, which allows only the PVD coating to be removed without damaging the substrate.
従来、装飾品被膜の剥離方法として、ＰＶＤ被膜を薬品
で剥離後、装飾品の表面に研磨を行なっていた。Conventionally, the method for removing coatings on decorative articles has been to remove the PVD coating with chemicals and then polish the surface of the decorative article.
しかしながら、前記従来方法においては、ＰＶＤ被膜剥
離後、素地が荒れてしまうので研磨工程を入れな（ては

ことにより寸法に変化が生じるなどの問題があった。However, in the conventional method, after the PVD coating is removed, the substrate becomes rough, so a polishing step is required (which requires a lot of man-hours and is expensive), and polishing causes changes in dimensions. There were other problems.
本発明の目的は、上述した従来の欠点を無＜シ。The object of the present invention is to eliminate the above-mentioned conventional drawbacks.
素地を荒らすことなく、装飾品被膜を剥離する方法を提

を特徴とするものである。The structure of the present invention is that in a method for peeling off a PVD film formed on a surface of an ornament, a Ni layer or an alloy mainly composed of Ni is formed by wet plating as a first layer between the surface of the ornament and the PVD film, starting from the bottom layer. , a metal layer or an alloy layer mainly composed of at least one of Pd, Au, and Pt is formed by wet plating or vapor phase plating as the second layer, and then only the PVD film is peeled off using a chemical. That is.
以下本発明の実施例を図面に基づいて詳細に説明する。 Embodiments of the present invention will be described in detail below based on the drawings.

品質にならない場合に、ＰＶＤ被膜４を剥離して、再度
ＰＶＤ被膜４を被覆して再生が必要となる。(Example 1) A watch case made of a prepared alloy, which is an ornament 1, is coated with a Ni alloy layer 2 with a thickness of about 5μ by wet electrolytic plating, and a PD alloy layer 2 with a thickness of about 3μ by wet electrolytic plating. 3 and set it in the ion blating device Pelger. Next, after exhausting the inside of the Pelger, Ar gas is introduced to make the pressure 1 , and irradiate the metal Ti evaporation source with an electron beam at an appropriate acceleration voltage to vaporize titanium and ionize Ti vapor and N2 gas.
A PVD film 4 of TiN is formed on the surface of the PD alloy layer 30. At this stage, the product is complete, but if for some reason the PVD coating 4 does not achieve the desired quality in color tone, film quality, etc., it can be recycled by peeling off the PVD coating 4 and covering it again. Is required.

ことができ、再び。In this case, the decorative article coated by the above method is immersed in a hydrofluoric acid stripping solution at room temperature for 30 minutes. This allows the PV
Only the D coating 4 can be peeled off, and the surface of the PD alloy layer 6 can be returned to its state before the ion blasting treatment without becoming rough, and can be used again.
イオンブレーティング処理のみを行うことにより簡単に
ＰＶＤ被膜４の再生ができる。The PVD film 4 can be easily regenerated by performing only the ion blating process.

Since the surface of the alloy layer does not become rough, there is no need for polishing, and it can be easily peeled off and recycled. In addition, the finished product has a three-layer structure: a Ni@ or Ni alloy layer, at least one metal layer or alloy layer among Pd, Au, and Pt, and a PVD coating, so a decorative product with excellent corrosion resistance can be obtained. It will be done.
