〔産業上の利用分野〕
本発明は眼鏡枠あるいは装飾品などの模様形成方法に関

膜形成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 forming patterns on eyeglass frames or ornaments, and more specifically, the method is easy to operate and can also form extremely elaborate decorative patterns. , relates to a method for forming a titanium nitride film on pure titanium.
〔従来の技術および解決すべき技術的課題〕純チタンは
装飾材として優れており、純チタン製のブローチ、カフ
スボタンなどが世に出回っている。これは、純チタンを
ブローチやカフスボタンとして加工後、適宜マスキング

施し難いなどの欠点もあり、これが純チタン材の装飾品
への利用拡大を阻む原因になっていた。[Prior art and technical problems to be solved] Pure titanium is excellent as a decorative material, and brooches, cufflinks, etc. made of pure titanium are on the market. This is made by processing pure titanium into brooches and cufflinks, applying appropriate masking, and then electrolyzing the surface to create a blue or other color.The color is beautiful, but if you want to create a detailed decorative pattern, you will have to do detailed masking. However, there were technical limits to the creation of precise patterns. In addition, if impurities are mixed in during the processing of pure titanium, beautiful colored patterns cannot be obtained by electrolysis, and if the processed surface is extremely uneven, masking may be difficult. This was a factor that hindered the expansion of its use.
また、純チタンは軽くて優れた屈撓性を有することから
眼鏡枠の母材としては優れたものだが、銀白色の冷やか
な色調を持つのが難点であった。In addition, pure titanium is lightweight and has excellent flexibility, making it an excellent base material for eyeglass frames, but it has a disadvantage in that it has a cool silvery-white color.
そこで、純チタンの眼鏡枠に樹脂塗料を塗布したものが
登場したが、樹脂塗料が剥離し易い欠点があった。そこ
で、眼鏡枠表面にイオンプレーティフグ法で有色硬質化
合物被膜を設けたものが登場した。この方法によると、
耐久性の高い色相が得られるが、加工が面倒であった。Therefore, eyeglass frames made of pure titanium coated with resin paint have been introduced, but they have the drawback that the resin paint easily peels off. Therefore, eyeglass frames have been developed in which a colored hard compound coating is applied to the surface of the frame using the ion plating method. According to this method,
Although a highly durable hue can be obtained, processing is troublesome.
即ち、眼鏡枠を洗浄して清浄にした後、密封容器となっ
ているイオンブレーティング装置にセットして、ポンプ
で装置内を真空に近いような状態してイオンブレーティ
ングを行わなければならないからである。In other words, after cleaning and cleaning the eyeglass frame, it must be placed in the ion blating device, which is a sealed container, and the ion blating must be performed using a pump to create a near-vacuum condition inside the device. It is.
しかも、このような面倒な工程を行っても複雑な装飾模
様は得難かった。そこで、眼鏡枠表面に凹部を形成し、
この凹部に塗料を塗布して塗料が剥げ難いようにした模
様形成方法が提案されたが、凹部形成作業と塗料塗布作
業という２つの工程を経なければならず煩瑣であり非能
率であった。Moreover, even with such a tedious process, it was difficult to obtain complex decorative patterns. Therefore, a recess is formed on the surface of the eyeglass frame,
A pattern forming method has been proposed in which paint is applied to the recesses to prevent the paint from peeling off, but this method requires two steps: forming the recesses and applying the paint, which is cumbersome and inefficient.
また、純チタンを電解して模様を形成しようとしても、
眼鏡枠加工の際に不純物の混入が避けられず、美しい発
色が得られないのである。Also, even if you try to form a pattern by electrolyzing pure titanium,
Impurities are unavoidable during the processing of eyeglass frames, making it impossible to obtain beautiful colors.
本発明は、純チタン金属表面に模様を形成する従来の方
法に上記の欠点があったことに鑑みてなされたもので、
耐久性が高く、加工が簡単で、たとえ少々不純物が含ま

を提供することを技術的！Ｉｆｆ、：するものである。The present invention was made in view of the above-mentioned drawbacks of the conventional method of forming patterns on the surface of pure titanium metal.
Our goal is to provide a method for forming patterns on pure titanium metal surfaces that are highly durable, easy to process, and can create delicate and beautiful decorative patterns even if they contain some impurities. Target! If: to do.
本発明者が上記課題解決のために採用した手段は以下の
とおりである。The means adopted by the present inventor to solve the above problem are as follows.
即ち、窒素を含む空気中で、純チタンの金属表面の所定

、不純物の混入にかかわらず繊細で美しい装飾模様を形
成することができる、有色化合物被膜形成による眼鏡枠
あるいは装飾品などの着色加工手段を提供した。That is, a method is adopted in which a laser is irradiated at a predetermined position on the metal surface of pure titanium in air containing nitrogen to increase the chemical activity of titanium and cause it to react with nitrogen to form a titanium nitride film and develop color. This provides a means for coloring eyeglass frames, ornaments, etc. by forming a colored compound film, which has a simple processing method and can form delicate and beautiful decorative patterns regardless of the presence of impurities.
以下、本発明を実施例に基づいて説明する。 Hereinafter, the present invention will be explained based on examples.

d: Oscillator that emits WAG laser (manufactured by NEC:
Using a laser marking device (manufactured by NEC Corporation: 5L475) equipped with Nd:YAG115) and setting the speed of the laser marking device to 10 mm/sec, the titanium in the irradiated part jumped out into the atmosphere and at the same time. When the electrons in titanium are excited, nitrogen in the atmosphere reacts with titanium, and a titanium nitride film is formed on the titanium surface of the 112811 frame, giving it a golden color.

まれる。Although the present embodiment is constructed as described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the claims. In particular, titanium products other than eyeglass frames, such as brooches and cufflinks, are decorated, and coatings other than gold are formed by changing the intensity and speed of the irradiated laser beam, especially coatings in colors such as blue, red, and black. Naturally, modifications such as applying a nitrogen jet to the laser irradiated surface to help form the titanium nitride film are also included within the scope of the present invention.

The keyaki forming method is highly durable because the pattern is formed by a titanium nitride film, and since the nitriding reaction can be carried out in the atmosphere, there is no need for a vacuum device, and the process can be performed without being affected by small amounts of impurities. Moreover, since the coating is formed only on the irradiated area of the laser, which can be made extremely small, elaborate decorative patterns can be easily formed. Furthermore, the processing cost was lower than processing methods using ion blating or coloring methods using electrolysis. In addition, decorative patterns can be easily formed even if the processed surface is highly uneven. This not only made it easier to form patterns on pure titanium eyeglass frames, but also opened up a new way to use pure titanium in decorative items.

窒化チタン被膜形成方法は産業上の利用価値が高い。As described above, the method for forming a titanium nitride film on pure titanium using the laser irradiation method of the present invention has high industrial utility value.
