Description
黒色クロムめっき層が膜厚0.15μm以上であることにより、膜厚での色バラツキが最少でおさえられる。また、黒色クロムめっき層がL*54以下の深い黒色であることにより、仮にその上の耐食性皮膜が黄色を発色する場合には、黄味がかりが目立つようになる。しかし、本発明では、耐食性皮膜が実質的に黄色を発色しないリン酸クロム(3価クロムである)又はリン酸モリブデンよりなるため、黒色クロムめっき層が黄味がかることはない。この耐食性皮膜が膜厚7nm以上であることにより、耐食性能を確保することができる。
樹脂基材の樹脂は、熱可塑性でも熱硬化性でもよく、特に限定されないが、アクリロニトリル・ブタジエン・スチレン共重合体(ABS)樹脂、ポリカーボネート(PC)樹脂、PC/ABS樹脂、アクリル樹脂、スチレン樹脂、ポリアミド樹脂、ポリカーボネート樹脂、ポリプロピレン樹脂、塩化ビニル樹脂、ポリウレタン樹脂等を例示できる。ABS樹脂、PC/ABS樹脂が強度、耐久性等の観点から好ましい。
樹脂基材の上には、次の下地めっき層を電解めっきするときに必要な導電層が形成される。導電層としては、特に限定されないが、無電解ニッケルめっき層を例示できる。
下地めっき層は、銅めっき層とニッケルめっき層とをこの順で含むものであり、銅めっき層は延性に富むため樹脂基材によく追従し、ニッケルめっき層は黒色クロムめっき層を美感保持するとともに電気化学的に防食する。ニッケルめっき層の具体的構成は、特に限定されず、1層でも複数層でもよい。
黒色クロムめっき層の膜厚は0.15μm以上であることがより好ましい。黒色クロムめっき層の膜厚の上限は、特に限定されないが、1μmが好ましい。1μmを超えると、膜内部応力が大きくなり、割れやすくなる。
耐食性皮膜を通して見た黒色クロムめっき層の色は、L*a*b*表色系でL*が44〜50、a*が1.5〜−1.5、b*が8〜ー8の範囲内であることが好ましい。L*が44未満では黒味が強すぎて金属感がなくなり、a*、b*がこの範囲外であるとそれぞれの色目(赤、緑、黄、青)が強くなる。
黒色クロムめっき層は、Feを含有すると、耐食性が向上するので好ましい。
3価クロムめっき浴に使用する3価クロム化合物としては、特に限定されないが、硫酸クロム(Cr2(SO4)3)、クロムミョウバン(CrK(SO4)2)、硝酸クロム(Cr(NO3)3)、塩化クロム(CrCl3)、酢酸クロム(Cr(CH3COO)3)等を例示できる。
耐食性皮膜の膜厚の上限は、特に限定されないが、20nmが好ましい。この膜厚が厚いと、やや白くなる。
化成処理液はリン酸と添加金属を含む水溶液であり、リン酸クロム被膜を形成する場合は添加金属が3価クロムであり、リン酸モリブデン被膜を形成する場合は添加金属がモリブデンである。
化成処理は無電解処理で行うこともできる。
車両用加飾部品(ラジエータグリル、フェンダ、ガーニッシュ、ホイールキャップ、バックパネル、エアスポイラー、エンブレム等)、電気製品(携帯電話、スマートホン、携帯情報端末、ゲーム機等)用筐体部品等を例示できる。特に風雨にさらされる車両用加飾部品は、高い耐食性能が求められるため、本発明を適用したときの有効性が高い。
図1及び表1に示すように、実施例1の黒色めっき樹脂部品は、ABS樹脂製の樹脂基材(導電層としての無電解ニッケルめっき層付き)と、樹脂基材上に形成された銅めっき層、半光沢ニッケルめっき層、光沢ニッケルめっき層、及びマイクロポーラスーニッケルめっき層をこの順で含む下地めっき層と、ニッケルめっき層の上に形成された3価クロムよりなる膜厚0.2μmの黒色クロムめっき層と、黒色クロムめっき層の上に形成されたリン酸クロム皮膜よりなる膜厚約10nmの耐食性皮膜を備えたものである。耐食性皮膜を通して見た黒色クロムめっき層の色は、L*a*b*表色系でL*が52.46、a*が0.67、b*が4.38であり、漆黒調の黒色である。耐食性皮膜による黒色クロムめっき層の黄味かがりはない。
