この発明は、チタン又はチタン合金材に包理のない均一
な着色皮膜を形成する陽極酸化法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an anodizing method for forming a uniform colored film without inclusions on titanium or titanium alloy material.
特開昭５０−１１０９４６号等でチタン又はチタン合金

工物を陽極（１）として電解質溶液中にこの陽極（１）
及び陰極（２）を浸漬すると共に、これらを固定し両極
間に電流を流して陽極（１）表面の酸化処理を行なうも
のである。JP-A-50-110946 and other publications propose an F,%+i oxidation method for forming a colored film on the surface of titanium or titanium alloy material. In this method, a workpiece made of titanium or a titanium alloy material is subjected to pretreatment such as degreasing, pickling, and cleaning of the surface, and then the workpiece is placed on an anode (1) as shown in Figure 4. This anode (1) in electrolyte solution as
The anode (1) surface is oxidized by immersing the anode (2) and the cathode (2), fixing them, and passing a current between the two electrodes.
ところが、このような処理を行なう場合、陰極（２）の
面積を陽極（１）の面積以上とする必要があり、定電流
密度で処理を行なう陽極酸化では。However, when performing such a treatment, the area of the cathode (2) must be larger than the area of the anode (1), and in anodization where the treatment is performed at a constant current density.
大型のチタン又はチタン合金材に着色皮膜を形成する時

いては電圧による色彩の変動が大きく、たとえ陰極（２
）面積を大きくとるとしても、通電ケーブルとの接点が
電極に局在している場合に、その局在に起因する色環が
大型の上記チタン材で生じ易いという欠点があった。When forming a colored film on a large titanium or titanium alloy material, a large power source is required, which limits the size of the workpiece. On the other hand, in anodizing titanium or titanium alloy materials, the color changes greatly depending on the voltage, and even if the cathode (2
) Even if the area is large, there is a drawback that if the contact point with the current-carrying cable is localized on the electrode, a color ring due to the localization is likely to occur in the large titanium material.
そのため本発明者等は、両電極間の間隙を一定に保ちな
がら、これらを相対的に移動させて陽極酸化処理を施す
構成を新たに創案した。Therefore, the present inventors have devised a new configuration in which the anodic oxidation process is performed by moving the two electrodes relative to each other while keeping the gap between the two electrodes constant.
又、一方、チタン又はチタン合金材の陽極酸化処理では
、陽極酸化前の該陽極表面の状態が影響し、表面に酸洗
むら等がある場合は着色皮膜中に色環となって現われ、
均一な着色皮膜が得られないことが多い。On the other hand, in the anodizing treatment of titanium or titanium alloy materials, the condition of the anode surface before anodizing is affected, and if there is uneven pickling on the surface, it will appear as a colored ring in the colored film.
A uniformly colored film is often not obtained.

ることもできる。Therefore, the present inventors have devised a structure in which a titanium or titanium alloy material is anodized, then polished to make its surface uniform, and then anodized again to obtain a uniformly colored film. did. Among the above-mentioned processes, when anodizing is performed, it is also possible to combine the above-described configuration in which the anodic oxidizing is performed by relative movement of both electrodes.

形成が終了した後、−旦、槽外に取り出して反転せしめ
、再び電解槽内に沈めて同様な操作を繰り返すことにな
る。そのため槽への出し入れによる作業効率の悪化が問
題となっていた。However, when implementing the former method of moving electrodes, for example, the anode is submerged in an electrolytic tank and the cathode is moved parallel to it from above to conduct electricity, so both sides of the plate, etc. When a colored film is to be formed, after the film formation on one side is completed, it must be taken out of the tank, turned over, and immersed in the electrolytic tank again to repeat the same operation. Therefore, there was a problem of deterioration of work efficiency due to loading and unloading the tank.
又、２回の陽極酸化処理と研磨を行なう後者の方法の実
施に当り、陽極酸化処理時に上記の電極移動型の方法を

ずチタン材は槽外に取り出さなければならず、作業効率
の低下はここにおいても同じである。In addition, when implementing the latter method, which involves two times of anodizing and polishing, if you try to implement the above-mentioned moving electrode method during anodizing, you will have to use titanium material during the process to polish the treated surface. must be taken out of the tank, and the same reduction in work efficiency occurs here as well.
本発明は以上のような問題を解決するためになされたも
ので、処理途中でチタン材等の加工物を電解槽から出し
入れする作業をなくそうという発想から発展して、電解
槽そのものを廃して電極移動型による陽極酸化処理を実
施できるようにしようとするものである。The present invention was made to solve the above problems, and was developed from the idea of eliminating the work of taking processed materials such as titanium materials into and out of the electrolytic cell during processing, and thereby eliminating the need for the electrolytic cell itself. This is intended to enable anodic oxidation treatment using a moving electrode type.
そのため本発明は、チタン又はチタン合金材を陽極とし

及び／又は陰極を移動させて陽極酸化処理を実施するに
当り、陽極と陰極の間に、雨間を電解質溶液で満たすこ
とのできる電解質溶液保持体を介在せしめて陽極酸化処
理を行なうようにしたことを基本的特徴としている。Therefore, the present invention uses titanium or a titanium alloy material as an anode, and when carrying out anodization treatment by moving the anode and/or cathode while maintaining a constant electrode gap between the anode and the cathode, the anode and the cathode are The basic feature is that an anodizing treatment is performed by interposing an electrolyte solution holder that can fill the rain gap with an electrolyte solution.

陰極を移動させて陽極酸化処理を行なうようにすること
を特徴としている。Furthermore, in carrying out the method of polishing and re-anodizing after the anodizing treatment, the second invention performs the anodizing treatment by relatively moving the two electrodes while keeping the distance between the two electrodes constant as described above. In this method, an electrolyte solution holder capable of filling the rain gap with an electrolyte solution is interposed between the anode and the cathode,
The method is characterized in that the anode and/or cathode are moved while maintaining a constant gap between these electrodes to carry out the anodic oxidation process.

入れる電解槽を不要とすることができる。The above-mentioned electrolyte solution holder is interposed between a cathode and an anode that are moved relative to each other, and is used to fill the space between the opposing surfaces of the cathode and the anode facing the cathode with the electrolyte solution. It is made of a porous material such as a sponge scrubber in order to absorb and retain the solution and keep both electrodes wet at all times. This electrolyte solution holder enables electrolysis between the two electrodes in the atmosphere, and makes it possible to eliminate the need for an electrolytic bath containing an electrolyte solution during the above-mentioned anodic oxidation treatment.

うな理由から上記の印加電圧は３ｖ以上３０Ｖ以下とす
るのが良い。In carrying out the second invention, it is preferable that the applied voltage for the first anodizing treatment be 3 V or more and 30 V or less. That is, an oxide film is formed on the anode surface by anodic oxidation, and the formation of this anodic oxidation film helps improve workability and grow a uniform surface in the next polishing step. At this time, an oxide film having a constant thickness is formed depending on the applied voltage, but if the applied voltage is greater than 30V, the next polishing process will take a long time and will be thicker. When an oxide film is formed, variations in the degree of oxidation film thickness corresponding to the surface texture of the titanium or titanium alloy material will be reflected in the surface texture after polishing, and even after the second anodic oxidation treatment, embedding will not occur. may occur. Moreover, when the applied voltage is less than 3V, there is almost no formation of an oxide film,
It becomes difficult to make the surface quality of the anode uniform. For this reason, it is preferable that the above applied voltage is 3V or more and 30V or less.

なる。However, the major difference between the two methods is the time and effort required to take out the workpiece (12) during the polishing process. In other words, the polishing work itself took about 20 minutes for both methods, but the time required from the end of the anodizing process to the start of the polishing process and the time required from the end of the polishing process to the start of the second anodizing process were As long as they are used, it only takes 5 minutes and 5 minutes, respectively, but in equipment that uses an electrolytic bath, it takes 20 minutes each because the electrolyte solution must be drained and freshly injected to remove the workpiece that has sunk in the electrolytic bath. It will take 20 minutes.
