〔産業上の利用分野〕
本発明は、金属の表面を多色化する表面処理方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a surface treatment method for making the surface of metal multicolored.
ステンレスやチタンなどの基材金属の表面に陽極酸化処
理を施して薄い酸化物層を形成すると、この薄い酸化物
層における反射光の干渉によって、美しい干渉色が得ら
れるので、この干渉色を利用したカラー材が開発されて
いる。また、陽極酸化の処理条件を変化させると、異な
る干渉色が得られるので、多色化する場合は、先ず、基
材金属の表面の一部をマスキングして陽極酸化し、マス
キングを剥離する。そして他の部分を再びマスキングし
て陽極酸化し、マスキングを剥離する工程を所定数繰り
返している。つまり、基材金属の表面の所定部位ごとに
陽極酸化の処理条件を変化させて多色化するので、陽極
酸化処理を数回行う必要がある。When a thin oxide layer is formed by anodizing the surface of a base metal such as stainless steel or titanium, beautiful interference colors can be obtained by the interference of reflected light in this thin oxide layer.Utilize this interference color. Colored materials have been developed. Furthermore, different interference colors can be obtained by changing the anodic oxidation processing conditions, so when multicoloring is desired, first, a part of the surface of the base metal is masked and anodized, and then the masking is peeled off. Then, the process of masking other parts again, anodizing them, and peeling off the masking is repeated a predetermined number of times. That is, since the anodic oxidation treatment conditions are changed for each predetermined portion of the surface of the base metal to produce multiple colors, it is necessary to perform the anodic oxidation treatment several times.
ところで、陽極酸化処理で得られる干渉色は、基材金属
の結晶相、結晶方位１粒界、酸化物、表面の汚れなどが
影響して微妙に変化するので、干渉色にバラツキが生じ
易く、再現性よく同一の干渉色を有する商品を大量生産
するのが困難である。By the way, the interference color obtained by anodizing treatment changes slightly due to the influence of the crystal phase of the base metal, crystal orientation 1 grain boundary, oxides, surface dirt, etc., so the interference color tends to vary. It is difficult to mass produce products that have the same interference color with good reproducibility.
このため、陽極酸化処理の前に、基材金属の表面をきれ
いに安定化させるための前処理が必要になるが、この前
処理に手間を要している。更には、ネガネフレームなど
のように加工履歴が複雑なものは１表面が酸化したり結
晶相が析出したりするので、前処理が非常に困難であり
、多色化する場合は陽極酸化処理が数回必要なためなお
さら手間を要していた。Therefore, before the anodizing treatment, pretreatment is required to cleanly stabilize the surface of the base metal, but this pretreatment requires time and effort. Furthermore, for items with a complicated processing history, such as negative frames, the surface may be oxidized or a crystalline phase may precipitate, making pretreatment extremely difficult. It was even more time-consuming because it needed to be done several times.
そこで本発明は、基材金属の表面に、陽極酸化処理が容
易で、しかも１回の陽極酸化処理でバラツキのない複数
の干渉色によって多色化できる表面処理方法を提供する
ことを目的とするものである。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a surface treatment method that allows easy anodic oxidation treatment on the surface of a base metal, and that can be multicolored with a plurality of consistent interference colors in a single anodic oxidation treatment. It is something.
本発明の表面処理方法は、耐食性の大きな基材金属の表
面に、マスキングを利用して陽極酸化可能な金属ないし
合金の１種類ないし２種類以上の薄膜が所定部位にそれ

必要に応じて露出させた基材金属に陽極酸化処理を施し
て多色化することを特徴とするものである。そして、基
材金属の耐食性が小さいときは、表面に耐食性の大きな
めっきを施してから同様の処理を行う。In the surface treatment method of the present invention, a thin film of one or more types of anodizable metal or alloy is vapor-deposited on the surface of a highly corrosion-resistant base metal using masking so that each is exposed at a predetermined location. Thereafter, this thin film and, if necessary, the exposed base metal are subjected to anodizing treatment to make them multicolored. When the corrosion resistance of the base metal is low, the same treatment is performed after plating the surface with high corrosion resistance.
すなわち、基材金属の表面に陽極酸化可能な金属ないし
合金を蒸着して１種類ないし２種類以上の薄膜を形威し
、それぞれの部位から異なった薄膜を露出（必要に応じ
て露出させた基材金属を含む、）させるので、−度陽極
酸化処理すると、各薄膜および必要に応じて露出させた
基材金属が酸化され、独自の干渉色を有するので多色化
できる。In other words, a metal or alloy that can be anodized is deposited on the surface of a base metal to form one or more types of thin films, and different thin films are exposed from each part (the exposed base is changed as necessary). Since the material contains metal (), when the material is anodized, each thin film and, if necessary, the exposed base metal are oxidized and have unique interference colors, so it can be multicolored.
また、薄膜をイオンブレーティング法などで蒸着してか
らこの薄膜に陽極酸化処理を施すが、イオンブレーティ
ング法などの蒸着は高真空中で行われるので、純度が高
くて表面が極めて美しく、陽極酸化処理を安定的に行う
ための前処理が不要であり、かつバラツキのない干渉色
を容易に得ることができる。もっとも、基材金属ないし
めっき層を露出させて陽極酸化処理を施すときは、この
前処理が必要であるが、面積が小さく、かつ−度の前処
理でよいので、従来よりも簡単である。In addition, a thin film is deposited using ion-blating methods, etc., and then anodized. However, since evaporation using ion-blating methods is performed in a high vacuum, the purity is high and the surface is extremely beautiful. Pretreatment for stably performing oxidation treatment is not necessary, and interference colors without variation can be easily obtained. However, this pretreatment is necessary when exposing the base metal or plating layer to perform the anodizing treatment, but it is simpler than the conventional method because the area is small and only one degree of pretreatment is required.
