A particularly preferred form of use is a method for evaluating the wear resistance of colored stainless steel materials using a chemical coloring method, which is primarily used as a building material.
〈従来技術とその問題点〉

を内装のみならず外装にまで使用する例が最近目立って
きているのが現状である。<Prior art and its problems> Conventionally, common steel and aluminum products have been the mainstream building materials, but in recent years, the use of stainless steel products has been increasing. Among these, the use of colored stainless steel materials by chemical coloring methods not only for interiors but also for exteriors has recently become more prominent.

れている。Colored stainless steel material has a spinel-type oxide film on its surface that is much thinner than that of colored aluminum material, and it appears colored due to light interference between the outer surface of this film and the base metal. It is known that the color tone changes from black, blue, gold, purple, and green as the film thickness increases.
この着色ステンレス鋼材は、特に外装用として用いる場

つために行う清掃時の汚れ取り作業で表面をこするとい
うこと等の理由から、耐候性の他に耐摩耗性が不可欠で
ある。This colored stainless steel material is particularly useful for exterior applications, where uniformity of color is required, as well as protection against collisions with foreign objects (raindrops, smudges, leopard, snow, dust, etc.) and cleaning to maintain the beauty of the surface. In addition to weather resistance, abrasion resistance is essential because the surface is often rubbed during cleaning operations.

■試験結果を数値化できず、判定が定性的である。Conventionally, methods for evaluating wear resistance include, for example,
The main method was a wear test using falling sand as specified in JIS) t 8601 (1968). 9
This is a method in which alumina powder is dropped from a high place and collided with a test piece placed on a slope, and the whitening of the surface of the test piece is visually judged. Therefore, with this conventional method, (1) test results cannot be quantified and judgments are qualitative.
■測定が大がかりで手間がかかる、 ■試験片の面積が大きく不経済である 等の欠点があった。■Measurement is extensive and time-consuming; ■The area of the test piece is large and uneconomical. There were other drawbacks.
そこで、これら耐候性や耐摩耗性を定量的にかつ簡便に
評価する方法があれば、特に建材内外装用として着色ス
テンレス鋼材の利用がより一層広がるものと思われる。Therefore, if there were a method to quantitatively and easily evaluate these weather resistance and abrasion resistance, it is thought that the use of colored stainless steel materials, especially for interior and exterior building materials, would be further expanded.

濃縮した領域が存在することが判明した。In order to identify the factors that determine the wear resistance and weather resistance properties of colored stainless steel materials, the present inventors conducted electrochemical measurements and surface instrument analysis, that is, measurements of cathode polarization curves in colored solutions, and ion Mass spectral analysis (IMMA)
Elemental analysis in the thickness direction of colored stainless steel material was carried out. As a result, it was found that by cathodic treatment (hardening treatment), a Cr-concentrated region existed on the outer layer side of the oxide film on the surface of the stainless steel material.

とを見出した。Based on these findings, the present inventors conducted extensive research focusing on the Cr concentration in the oxide film formed on colored stainless steel materials. It has been found that there is a correlation between the color difference between the worn area and the non-sliding worn area where no sliding is applied, and the Cr concentration.

開発したものである。That is, the present invention recognizes that the hardness of the surface of the colored film (hard thin film), which is the basis of the wear resistance of colored stainless steel materials, is an important factor. Based on the knowledge that there is a correlation between
It was developed.

材の摩耗の程度を評価し得る。The hardness of this colored film is Cr2, which is the main component of the film.
This is closely related to the degree of wear associated with physical abrasion and sliding of O3-based spinel oxide, and in order to obtain the evaluation method for wear resistance in the present invention, a sliding wear test was conducted under the following conditions. If done, it will accurately reflect the characteristics of the colored film, i.e.
The degree of wear of the colored stainless steel material can be evaluated based on the correlation with the amount of Cr on the surface of the coating.

を求める。That is, in the present invention, in the sliding wear test, an abrasive is used to slide the surface of the colored surface film to create a scratched state, and this slidingly worn part is compared with the non-slidingly worn part of the same surface film. The color difference (ΔE) is measured by colorimetry between two areas of
seek.
色差（ΔＥ）は、着色表面皮膜の摺動摩耗部分と非摺動
摩耗部分における各々の表面の色調（Ｌ、ａ、ｂ値）を
測定することにより下式によって得られる。The color difference (ΔE) is obtained by the following formula by measuring the color tones (L, a, b values) of each surface of the colored surface coating in the sliding abrasion area and the non-sliding abrasion area.
ΔＥ ＝ ＬＨ−Ｌ２ ＋ ８１−８２ ”（
ｂｓ−ｂ２）２ここで、Ｌ値は０〜１００段階に分れ、
数値が大きいほど白色（明色）になる。ΔE = LH-L2 + 81-82'' (
bs-b2)2 Here, the L value is divided into 0 to 100 stages,
The larger the number, the whiter (brighter) the color becomes.
また、ａ値は、値が大ぎいほど色合いは赤く、値が小さ
くなるにつれ緑色なるという関係にある。Further, the a value has a relationship such that the larger the value, the redder the color, and the smaller the value, the greener the color.
また、ｂ値は、値が大きいほど色合いは黄色で、値が小
さくなるにつれ青色にあるという関係にある。Furthermore, the larger the b value, the more yellow the color, and the smaller the value, the more blue the color is.
この色差の値が小さいほど、摩耗程度は少ない、即ち耐
摩耗性は良いとしてこの色差の値で着色ステレンス鋼材
の耐摩耗性の評価を行う。The smaller the value of this color difference, the lower the degree of wear, that is, the better the wear resistance, and the wear resistance of the colored stainless steel material is evaluated based on the value of this color difference.
本発明における耐摩耗性の評価方法において、摺動摩耗
試験の好ましい条件を以下に記す。In the method for evaluating wear resistance in the present invention, preferable conditions for the sliding wear test are described below.
■研磨材は＃３２０〜＃８００の酸化クロム紙が適する
。■Chromium oxide paper of #320 to #800 is suitable as the abrasive material.
■摺動の際の負荷は３００〜６００ｇ重が適する。■A suitable load during sliding is 300 to 600g.
■摺動回数は２〜１５回が適する。■A suitable number of sliding movements is 2 to 15 times.
■摺動方法は回転型が最適である。■Rotating type is the best sliding method.
以下に上記範囲が好ましい理由を述べる。The reason why the above range is preferable will be described below.
研磨材の番手は＃１００〜２４０だと粗くて均一に摩耗
できず、＃１０００という細かいものだとうまく摩耗し
ていかないので、＃３２０〜＃８００が好適である。
また研磨材は、炭化ケイ素（Ｓ ｉ Ｃ）は研磨面に炭
素が、アルミナ（ＡＩ１２０ｓ ）では白い粉末が付着
して取れない欠点があるが、酸化クロム（Ｃｒ２ ｏ３
）では研磨面に緑色の酸化クロムが付着することはな
いので、この用途に適する。If the abrasive material is #100 to #240, it will be too coarse to wear uniformly, and if it is as fine as #1000, it will not wear well, so #320 to #800 is preferable.
Furthermore, as for abrasive materials, silicon carbide (S i C) has carbon on the polishing surface, and alumina (AI120s) has the disadvantage that white powder adheres to it and cannot be removed, but chromium oxide (Cr2 o3
) is suitable for this purpose because green chromium oxide does not adhere to the polished surface.
負荷は、３００ｇ重未満だと摩耗が十分にできず、６０
０ｇ重を超えると摩耗程度が大きくなり変化がつかめな
いので、３００〜６００ｇ重が好ましい。 皮膜が厚膜
となり、色調が金色、緑色となるに従い上記範囲内で負
荷を大きくすればよい。If the load is less than 300g, sufficient wear will not occur;
If the weight exceeds 0g, the degree of wear increases and changes cannot be detected, so a weight of 300 to 600g is preferable. As the film becomes thicker and the color becomes more golden or green, the load may be increased within the above range.
摺動回数としては、あまり多いと、薄膜の茶色や黒色の
場合素地が露出して試験の意味をなさないので２〜１５
回が良い。The number of times of sliding is 2 to 15, because if the number of sliding is too high, the base material will be exposed in the case of thin brown or black films and the test will be meaningless.
The times are good.
摺動方法には、一方向、往復、回転とあるが一方向、往
復は装置上無駄が多く、回転式によれば、比較的簡潔な
機構で試験を行い得る。Sliding methods include unidirectional, reciprocating, and rotating, but unidirectional and reciprocating is wasteful in terms of equipment, whereas the rotating method allows tests to be performed with a relatively simple mechanism.
すなわち本発明によれば、着色ステンレス鋼材に摺動摩
耗領域と非摺動摩耗領域とを形成し、これらの色差な測
定することにより、この色差の値が大きければ°耐摩耗
性が劣り、小さいほど（例えば２．０以下）耐摩耗性に
優れるということが簡便にかつ定量的に求められる。That is, according to the present invention, a sliding wear area and a non-sliding wear area are formed in a colored stainless steel material, and the color difference between these areas is measured. It can be simply and quantitatively determined that the higher the abrasion resistance (for example, 2.0 or less), the better the wear resistance.
