Description
本発明は、金属表面処理液及び金属表面処理方法に関する。 The present invention relates to a metal surface treatment liquid and a metal surface treatment method.
従来、種々の金属、特にアルミニウム又はアルミニウム合金の着色において、灰色系の色調を得るには陽極酸化や陽極酸化皮膜に染料を吸着させる方法が一般的である。 Conventionally, in coloring various metals, particularly aluminum or aluminum alloys, a method of adsorbing a dye on an anodized or anodized film is generally used to obtain a grayish color tone.
例えば、特許文献１には、アルミニウム又はアルミニウム合金の素地表面に形成した電解発色又は自然発色による発色被膜を、電解着色可能な皮膜構造とした後、電解着色を行って、色を重ね合わせて新たな色調の皮膜を得ることを特徴とするアルミニウム及びアルミニウム合金の電解着色方法が開示されている。そして、このような構成によれば、従来の電解着色方法では得られない様々な中間色を含む種々の色調を得ることができる電解着色方法を提供することができる、と記載されている。 For example, in Patent Document 1, a color-developing film formed on the surface of an aluminum or aluminum alloy base material by electrolytic coloring or natural coloring is formed into a film structure capable of electrolytic coloring, and then electrolytic coloring is performed to superimpose the colors. A method for electrolytically coloring aluminum and an aluminum alloy, which comprises obtaining a film having a different color tone, is disclosed. Then, it is described that according to such a configuration, it is possible to provide an electrolytic coloring method capable of obtaining various color tones including various neutral colors which cannot be obtained by the conventional electrolytic coloring method.
しかしながら、従来、金属表面を灰色系の色調に着色するには、例えば、アルミニウム又はアルミニウム合金であればアルマイトを利用する必要があった。すなわち、金属表面を灰色系の色調に着色するには、酸化膜を表面に有する金属を利用する必要があり、処理工程が多く、処理効率の改善が望まれている。 However, conventionally, in order to color the metal surface to a grayish color, it has been necessary to use alumite, for example, in the case of aluminum or an aluminum alloy. That is, in order to color the metal surface to a grayish color tone, it is necessary to use a metal having an oxide film on the surface, and there are many treatment steps, and improvement in treatment efficiency is desired.
