本発明の硬質装飾部材を構成する各積層は、スパッタリング法、CVD法、イオンプレーティング法などによって形成することができるが、好ましくは、反応性スパッタリング法により形成される。
本発明により提供される時計は、その構成部品の一部、例えば、外装部品に上述した白色硬質装飾部材を有することを特徴とする。時計は、光発電時計、熱発電時計、標準時電波受信型自己修正時計、機械式時計、一般の電子式時計のいずれであってもよい。このような時計は、上記白色硬質装飾部材を用いて公知の方法により製造される。時計はシャツとの擦れや、机、壁などに衝突することにより傷が入りやすい装飾部材の一例である。本発明の白色硬質装飾部材を時計に形成することにより、長年にわたり傷が入りにくく、外観が非常にきれいな状態を維持することが可能となる。
耐傷性試験は、JISに定めるSUS316L基材に装飾膜を施し、アルミナ粒子が均一に分散した磨耗紙を試験サンプルに一定加重で接触させ、一定回数擦ることで傷を発生させる。傷がついた試験サンプルの表面を、キズの方向と垂直方向にスキャンして表面粗さを測定し、二乗平均荒さとして耐傷性の評価とした。傷の発生量が多いほど、傷の深さが深いほど二乗平均荒さの数値が大きくなり、逆に傷の発生量が少ないほど、傷の深さが浅いほど二乗平均粗さの数値が小さくなることから、耐傷性を数値的に評価することができる。
膜硬度測定は、微小押込み硬さ試験機(FISCHER製H100)を用いて行った。測定子にはビッカース圧子を使用し、5mN荷重で10秒間保持した後に除荷を行い、挿入されたビッカース圧子の深さから膜硬度を算出した。
キャス(CASS)試験はJIS−H 8502に準拠された、酢酸酸性の塩化ナトリウム溶液に塩化第二銅を添加した溶液を噴霧した雰囲気に48時間設置し、装飾膜の剥離および変色を観察し耐食性の評価とした。
80℃、60%の熱硝酸および、硝酸40%硫酸25%弗酸4%溶液にサンプルを浸漬させ、装飾膜が基材から完全に剥離した時間を測定してエッチング性の評価とした。
本発明の白色硬質装飾部材の第1の実施例を図2、図3および図4を用いて説明する。図2は白色硬質装飾部材20の断面模式図、図3はメタンガス導入量による硬度と輝度変化を示す図、図4は白色硬質装飾部材20の耐傷性測定図である。
本発明の白色硬質装飾部材の第2の実施例を図5、図6および図7を用いて説明する。図5は白色硬質装飾部材30の断面模式図、図6はメタンガス導入量による硬度と輝度変化を示す図、図7は白色硬質装飾部材30の耐傷性測定図である。

本発明の白色硬質装飾部材の第4の実施例を図11、図12および図13を用いて説明する。図11は白色硬質装飾部材50の断面模式図、図12はメタンガス導入量による硬度と輝度変化を示す図、図13は白色硬質装飾部材50の耐傷性測定図である。
本発明の硬質装飾部材の第5の実施例を図14、図15および図16を用いて説明する。図14は硬質装飾部材60の断面模式図、図15はメタンガス導入量による硬度と輝度変化を示す図、図16は硬質装飾部材60の耐傷性測定図である。
実施例5の白色硬質装飾部材60における色上げ傾斜層65は、炭素含有量を傾斜的に減少させることにより、L*の上昇が傾斜的に行われ、外観カラーを基材であるSUS316L材に近づけると共に、耐磨耗層74との密着性が高いことから、傷が入っても剥離しにくく、また傷が目立ちにくいという効果にも寄与している。
図16は実施例5の白色硬質装飾部材60における耐傷性能を測定した図である。比較として特許文献1を参考に作成した装飾部材110、本発明に係わる実施例5の白色硬質装飾部材60、硬質膜を形成していないSUS316L基材の耐傷性(二乗平均粗さ)を測定した結果である。図16から、本発明の実施例5の白色硬質装飾部材60は、硬質膜を形成していないSUS316L基材に対してはもちろん、特許文献1を参考に作成した装飾部材110と比較してもはるかに耐傷性能が良くなっていることが確認された。
表7にはMoNbCr合金の合金比率による硬度、耐食性、エッチング性及び総合評価を示した。MoNbCr合金は、Crの添加によりMoNb合金と比較して膜硬度が低下することにより耐傷性が低下するが、輝度の高いCrが入ることでよりステンレス色に近い高い輝度、色調を得ることが可能となる。またCrは非常に耐食性に優れた材料であることから、Crを含有させることにより耐腐食性能、特に次亜塩素酸塩に対する耐食性能を大幅に向上させることが可能となる。
高級感のある色感、耐腐食性能にすぐれた白色硬質装飾部材として使用する場合、Cr比率を高めた方が効果的であるが、Cr比率を高くしすぎるとエッチング性能が大幅に低下し、また膜硬度の低いCr比率を高くしすぎると耐傷性能が低下することから、Cr比率は実験範囲で0.5wt~30wt%が望ましく、0.5~20wt%がより望ましい。
Crは人体に対してアレルギー性を示す材料であることから、時計の外装部品、眼鏡やアクセサリーなどの装身具に使用する場合においては、金属アレルギーに対する注意が必要となる。したがって、金属アレルギーの注意が必要な用途には、Cr以外のTi,Hf、Zrを使用するか、または、Cr、Ti、Hf,Zrを使用せず、(Mo,W)と(Nb,Ta)の合金を使用することが好ましい。
表8には実施例5のCrに変えてTi、Hf、Zrを10wt%合金化させたMoNb合金膜の耐食性、エッチング性及び総合評価を示した。Crと同様にTi、Hf、Zrといった4族を合金化させることにより耐食性、特に次亜塩素酸に対する耐食性が向上する。しかしながらTi、Hf、Zrといった材料は輝度が低い材料であるため、含有比率を高めると輝度の低下が著しくなり、高級感が得られなくなってしまう。またTi、Hf、Zrの含有比率を高めた合金で窒化物膜を形成した場合若干の着色が現れ、高級感のある白色を得られなくなってしまうことから、Ti、Hf、Zrの含有比率は実験範囲で0.5wt~20wt%が望ましく、0.5~10wt%がより望ましい。
Mo、W、Crは基材との密着性が高く、またMo、Crは特に輝度が高い材料である。しかしながらMo、Crは膜硬度が高くなく、高い耐傷性能が得られない。またMo、Wは耐食性能が劣る。Nb、Taは膜硬度が高く、耐食性も高い材料であるが、基材との密着性が低く、輝度も低いことから装飾部材としての高級感が得られない。またCrは材料の中で最も耐食性能が高い材料の1つである。本発明においては合金を作成することでそれら金属の長所、短所をそれぞれ補完させることが可能となり、高級感のある色感と、特に長期間にわたり耐傷性、耐腐蝕性に優れる硬質装飾部材を提供できるのである。Mo、W、Nb、Ta、Cr(Ti、Hf、Zr)を2種以上合金化させた膜を作ることは容易であり、膜硬度、輝度、耐食性、密着性等を自由にコントロールでき耐傷性を飛躍的に向上できる。またそれら合金の窒化物、炭化物、酸化物、酸窒化物、酸炭化物、窒炭化物、酸窒化炭化物も反応性ガスの調整により容易に作成でき、求める特性に応じて変更が可能である。
以上に述べたように、本発明の白色硬質装飾部材では、金属との密着効果が高く輝度の高い金属と、膜硬度が高く耐食性の高い金属およびアレルギー性能を調整する金属の合金による膜を使用して、基材上に密着効果の高い合金密着層と、反応ガス含有量が傾斜的に増加した合金傾斜密着層と、硬度の高い耐磨耗層と、反応ガス含有量が傾斜的に減少した合金色上げ傾斜層からなっているため、基材と膜間の密着性が著しく向上し耐傷性が向上すると共に、膜硬度の高い耐磨耗層を厚く形成できることから耐傷性をさらに向上させることができる。加えて合金比率により膜硬度、輝度、耐食性、密着性、剥離性等耐食性、輝度、エッチング性を自由にコントロールでき、さらにアレルギー性能も調整できることから、装身具、装飾品として従来技術では得られない高耐傷性能と高級感、高耐食性を併せ持った装飾部品を得ることができる。
本発明は、傷や磨耗などによる外観品質の低下を抑制し、かつ高級感のある色調を有した白色硬質装飾部材を提供し、さらに色調、耐腐食性能、エッチング性能、アレルギー性能を自由にコントロールできるため、時計の外装部品、眼鏡やアクセサリーなどの装身具、装飾品、スポーツ用品などの装飾部材に利用できる。
