【発明の詳細な説明】
本発明は、窒化チタンを被覆した時計用外装部品に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a watch exterior part coated with titanium nitride.
さらに詳しくは、チタンと窒化チタンを層状に不連続に
被覆し、耐蝕性咳すぐれた時計用外装部品を提供するも
のである。More specifically, the present invention provides a corrosion-resistant exterior part for a watch by discontinuously coating titanium and titanium nitride in layers.
従来より、ステンレス鋼、黄銅、亜鉛合金に反応性イオ
ンブレーティング法により窒化チタン膜を形成する方法
が開発されている。Conventionally, methods have been developed for forming titanium nitride films on stainless steel, brass, and zinc alloys by reactive ion blating.
しかしながら、これら材料に窒化チタンを被覆して時計
用外装部品にした場合、耐蝕性、密着性が悪く、携帯中
に窒化腰が剥離したり、錆を生ずるなどの欠点があった
。However, when these materials are coated with titanium nitride to make exterior parts for watches, there are drawbacks such as poor corrosion resistance and adhesion, and the nitride film peels off while being carried or rusts.
即ち、窒化チタンは金属の窒化物であり、極めて錆にく
い性質を有するが、下地のステンレス鋼。In other words, titanium nitride is a metal nitride and has extremely rust-resistant properties, but the stainless steel base.
黄銅、亜鉛合金との間に塩水のような電解質が存在する
と、局部電池が形成され腐蝕が起きる。If an electrolyte such as salt water is present between the brass and zinc alloys, a local battery will form and corrosion will occur.
本発明は、これらの欠点を除去し、耐蝕性、密着性に優

ることに基づ〈。The present invention eliminates these drawbacks and provides an exterior part for a watch that has excellent corrosion resistance and adhesion. That is, to prevent pinholes from penetrating the coating, titanium was first coated, and a titanium nitride layer was formed thereon. In other words, it is based on blocking renhole by discontinuously coating another material in a layered manner.
さらに、この不連続層を２．３・・・・・・層とするた
め、チタンと窒化チタンの層をサンドイッチ状に多層に
交互に形成した。Furthermore, in order to make this discontinuous layer into 2.3 layers, layers of titanium and titanium nitride were alternately formed in a sandwich-like manner.
本発明より過酷な携帯条件下でも、錆の生じないしかも
密着性のよい、時計外装部品の提供が可能になつｔｏ

属が腐蝕し、錆として下地金属が表面に溶出するもので
ある。The present invention makes it possible to provide watch exterior parts that do not rust and have good adhesion even under harsh carrying conditions. Although titanium itself is extremely resistant to corrosion, the underlying metals, such as stainless steel, brass, and zinc alloys, have a slightly less noble electrochemical potential than titanium nitride, and in the presence of electrolytes, they form local batteries and cause pinholes. Through this process, the underlying metal corrodes, and the underlying metal is eluted to the surface as rust.
以下に、実施例により説明、スる。The following is an explanation based on examples.
〈実施例１〉
イオンブレーティング法により時計用外装ケース表面に
チタン膜を（Ｌ２／ｊ惰被覆し、その上に１．０μ慣の
窒化チタン膜を被覆した。<Example 1> A titanium film (L2/J) was coated on the surface of a watch exterior case by the ion blating method, and a 1.0 μm titanium nitride film was coated thereon.
ケース材質は１８−８ステンレス鋼製で、表面は鏡面仕
上げおよび筋目仕上げしである。The case material is made of 18-8 stainless steel, and the surface is mirror-finished and grained.
部品を人工汗浸漬試験（，３・５℃、９６Ｈ）、塩水噴

5. Finally, a 15 μm groove was formed with titanium nitride to give a total film thickness of 1 kt and 5 μm.
ケース材質、仕上げは、実施例１と同一である。The case material and finish are the same as in Example 1.
部品を実施例１と同一の方法で、耐蝕性試験に供したと
