Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は耐食性および耐指紋性に優れる建材用ステン
レス表面処理鋼板に関する。Description: TECHNICAL FIELD The present invention relates to a stainless steel surface-treated steel sheet for building materials having excellent corrosion resistance and fingerprint resistance.
（従来の技術） ステンレス鋼板は優れた耐食性およびステンレス鋼板
独特の肌、色調を生かして、ビル内外装、エレベータ内
壁、手摺等の建材用途に幅広く使用されている。(Prior Art) Stainless steel sheets are widely used for building materials such as interior and exterior of buildings, elevator inner walls, handrails, etc., utilizing their excellent corrosion resistance and the unique skin and color tone of stainless steel sheets.
建材用ステンレス鋼板の表面処理方法として従来行わ
れている方法は鏡面仕上げ、ヘアライン仕上げ等の機械
研磨仕上げおよび化学エッチング仕上げである。Conventional methods for surface treatment of stainless steel sheets for building materials include mechanical polishing, such as mirror finishing, hairline finishing, and chemical etching.
一方、近年のファッショナブル化の動きにともない、
建材用ステンレス鋼板にも意匠性が求められるようにな
り、化学発色ステンレス鋼板あるいは塗装ステンレス鋼
板が開発され、市販されている。On the other hand, with the recent trend of fashionability,
Designability is also required for stainless steel sheets for building materials, and chemically colored stainless steel sheets or painted stainless steel sheets have been developed and marketed.
しかし、化学発色ステンレス鋼板は化学的活性度の不
均一性に起因する色ムラが発生しやすい、あるいは不働

上げ、ヘアライン仕上げ等の表面肌が失われる欠点を有
している。However, chemically colored stainless steel sheets have the disadvantage that color unevenness is likely to occur due to non-uniformity of the chemical activity, or the passive film is thin and has poor abrasion resistance and is easily discolored by friction with a brush or the like. doing. Further, since the coated stainless steel plate has a coating film thickness as large as about 20 μm, it has a drawback that the surface skin such as mirror finish and hairline finish is lost.
これら化学発色ステンレス鋼板および塗装ステンレス
鋼板の欠点を鑑みて、最近スパッタリング、イオンプレ
ーティング、プラズマCVD等のプラズマコーティングに
よりステンレス鋼板の表面にセラミックス被膜を形成
し、意匠性を高めようとする試みが盛んに行われてい
る。In view of the drawbacks of these chemically colored stainless steel sheets and painted stainless steel sheets, recent attempts have been made to enhance the design by forming a ceramic film on the stainless steel sheet surface by plasma coating such as sputtering, ion plating, or plasma CVD. It has been done.
セラミックス膜は例えば、TiNは金色、TiAlNはブロン
ズ色といったように生成物質に基づく一定の色を呈する
ため、化学発色ステンレス鋼板のような色ムラは生じに
くく、かつ膜硬度はHv2000と非常に硬いため耐摩耗性は
良好である。また、膜厚は0.2μｍ〜５μｍと比較的薄
いため被膜後も鏡面仕上げ、ヘアライン仕上げ等の表面
肌は変化しない。Ceramic films, for example, have a constant color based on the generated material, such as gold for TiN and bronze for TiAlN. The wear resistance is good. Further, since the film thickness is relatively thin, 0.2 μm to 5 μm, the surface skin such as mirror finish or hairline finish does not change even after coating.
（発明が解決しようとする問題点） しかし、プラズマコーティングによりセラミックスの
被膜を形成した建材用ステンレス表面処理鋼板はセラミ
ックス被膜中にピンホールの存在が避けられず、腐食環
境中にさらされると該ピンホール部からステンレス鋼板
の腐食が進行する。(Problems to be Solved by the Invention) However, in a stainless steel surface-treated steel sheet for building materials in which a ceramic coating is formed by plasma coating, the presence of pinholes in the ceramic coating is inevitable, and when exposed to a corrosive environment, the presence of the pinholes increases. Corrosion of the stainless steel plate proceeds from the hole.
このような不都合を解消すべく種々の検討がなされ、
例えば特開平１−172557にはセラミックス被膜のピンホ
ール部にクロムおよびクロム酸化物の複合物を埋設する
ことによる耐食性向上策が開示されている。Various studies have been made to resolve such inconveniences.
For example, Japanese Patent Application Laid-Open No. 1-172557 discloses a measure for improving corrosion resistance by embedding a composite of chromium and chromium oxide in a pinhole portion of a ceramic film.
しかし、上記方法は塩水噴霧試験のように試験片表面
がたえず塩水によって洗われているような環境において
は良好な耐食性を示すが金属粉等の塵埃が存在する実環
境では、塵埃からのもらい錆から腐食が進行する欠点を
有している。However, the above method shows good corrosion resistance in an environment where the surface of the test piece is constantly washed with salt water as in the salt spray test, but in an actual environment where dust such as metal powder is present, rust from the dust can be obtained. Has the disadvantage that corrosion proceeds.
また、プラズマコーティングによりセラミックス被膜
を形成した建材用ステンレス表面処理鋼板は非常に色が
鮮やかであるため、エレベータ内壁等意匠性が要求され
る部材に適しているが、色が鮮やかなだけに指紋が付着
すると、目だちやすいという欠点を有している。In addition, stainless steel surface treated steel sheets for building materials with ceramic coating formed by plasma coating are very vivid in color, so they are suitable for members requiring design properties such as elevator inner walls. There is a drawback that when adhered, it is easy to see.
