ティング方法も気相を使ったものに変わってきている。BACKGROUND OF THE INVENTION Up to now, steel plates such as stainless steel have been colored using paint or by forming an oxide film, such as ink treatment. Various methods have been proposed for further drawing patterns using these methods. However, with the recent development of vapor phase coating technology, it has become possible to coat substances that were previously thought to be impossible to coat, and improvements in adhesion, weather resistance, and scratch resistance have become possible. Since then, the coating method has changed to one using a gas phase.
同時に、模様をあしらったステンレス鋼板への要求もま
すます大きくなってきており、今では気相コーティング
による鋼板の着色模様を付与する技術が重要となってき
た。At the same time, the demand for patterned stainless steel sheets is increasing, and technology for imparting colored patterns to steel sheets through vapor phase coating is now important.
その基礎的な技術としては、ＬＳＩなどの製造法に大い
に利用されているマスキングによるパターンニング技術

にこの方法が唯一の方法でもあった（例えば、特開昭５
１−１０１８３ ）。The basic technology is patterning technology using masking, which is widely used in manufacturing methods for LSIs and the like. In other words, as a method for applying decorative patterns over a wide area using vapor phase coating, 10N-OFF coating by masking has been used up until now, but this method was also the only method (for example, Showa 5
1-10183).

、この部分から剥離を起こすなどの問題を抱えていた。This method involves placing a mask with the desired pattern cut out on the board you want to color! ! In this method, the coating is applied as is, and the mask is then removed to transfer the pattern onto the steel plate. However, in such a method,
Masks require a lot of effort to make, especially when they have complicated patterns, and are extremely inefficient when it comes to producing a wide variety of products in small quantities. Furthermore, there is a step corresponding to the film thickness in the boundary area between the masking part and the coating part, which causes problems such as peeling from this part.

飾的な模様を持った鋼板を得る。Means for Solving the Problems The present invention involves irradiating a chromium-containing alloy steel that is in contact with an aqueous solution of an oxidizing acid or its salt with a laser beam, and then further coating the surface of the chromium-containing alloy steel that has been irradiated with the laser in a vapor phase. This is a method for producing a colored patterned steel sheet. In other words, when performing vapor phase coating, laser treatment is applied to the substrate surface in advance to create irradiated and non-irradiated areas, and the difference in film formation speed or adhesion between the two is used to create decorations. Obtain a steel plate with a pattern.

響を受けることを見い出した。As the vapor phase coating method, CVD using light or plasma, PVD such as ion blating, sputtering, and vacuum evaporation are selected depending on the substance to be coated and the purpose of the molded product. Generally ff1
It is widely known that the M speed or adhesion is greatly affected by the surface properties of the substrate (cleanliness, roughness, etc.) and substrate temperature among many coating conditions. Through experiments and studies, the present inventors have found that the surface composition, crystal structure, and crystal orientation are also greatly affected.
一方、酸化力を有する酸もしくはその塩の水溶液を合金
鋼に接した状態でレーザー照射することにより、表面化

酸系で２％以上、クロム酸、過マンガン酸系で５％以上
が望ましい。On the other hand, by laser irradiating an aqueous solution of an acid or its salt with oxidizing power while it is in contact with alloy steel, a chemical reaction occurs on the surface, and specific components such as chromium, nickel, titanium, molybdenum, and niobium are generated in the irradiated area. A significant thickening occurs. The solution used at this time is nitric acid or nitrate,
Aqueous solutions containing one or more of chromic acid or chromates, permanganic acid or permanganates, etc. are useful. Furthermore, if the concentration is too low, the oxidizing power will be lost, so it is desirable that the concentration be 2% or more for nitric acid, and 5% or more for chromic acid or permanganate.
レーザー照射による模様化の方法は、原図をコンピュー
ターに読みこませ、コンピューターからの出力で基板側
を上下左右に移動させてレーザー照射部分を基板−ヒに
作り込んでいく。In the method of creating patterns using laser irradiation, the original drawing is loaded into a computer, and the output from the computer is used to move the board up, down, left and right, and the laser irradiated area is created on the board.
含クロム合金鋼はクロムを７％以上、より好ましくは１

場合には、レーザー光の照射によって顕著なりロム等の
濃化が起きるために、その後の気相コーティングによっ
てクロム等の濃化部分と非照射部分を別の色に着色する
ことができる。Chromium-containing alloy steel contains chromium of 7% or more, more preferably 1
In the case of chromium steel or nickel-chromium steel containing 2% or more, irradiation with laser light causes a noticeable concentration of chromium, etc., so the subsequent vapor phase coating separates the chromium-enriched part from the non-irradiated part. can be colored in a different color.
また、照射時間を変えることによってクロム濃化の程度
を変えることができるため、コーテイング後の色を変え
ることができる。Furthermore, since the degree of chromium concentration can be changed by changing the irradiation time, the color after coating can be changed.
コーティングには、ＴｉＮ 、 ８４Ｃなどの有色セラ

化学量論的組成からのずれに基づいた色の変化のため、
多くの場合色の変化は少なく地味な感じの模様を与える
。また、透明セラミックスを用いた場合には、膜は干渉
色を与えるため、見る角度により色が変わり、非常に鮮
やかな模様となる。Colored ceramics such as TiN and 84C, and transparent ceramics such as 5i02 and TiO2 are used for the coating. In the case of colored ceramics, due to color changes based on deviations from the stoichiometric composition of the compounds,
In most cases, there is little change in color, giving a plain pattern. Furthermore, when transparent ceramics are used, the film imparts interference color, so the color changes depending on the viewing angle, resulting in a very vivid pattern.

The Ti metal is melted and ionized using laser (IJ/pulse/2-pulse) irradiation and cathode gun), and nitrogen gas is introduced as a reactive gas into this atmosphere to react with Ti to form a TiN film on the substrate. It is something that makes you The produced film exhibited a golden yellow color, which is the material color of TiN, in the non-irradiated areas, and a greenish blue color in the irradiated areas. When this film was evaluated, the thickness of the blue pJ film in the irradiated area was 30% of that of the gold thin film. Further, although there was almost no deviation from the stoichiometric composition ratio of Ti and N in the gold thin film, it was unexpectedly large in the blue thin film with TiNα2.

When the film thickness was set to 5000, the film exhibited interference color, and a colored patterned steel plate was obtained, clearly reflecting the difference in film formation speed between the areas irradiated with laser light and the areas not irradiated with laser light.
