Abstract
【解決手段】無電解ニッケルめっき浴は、少なくとも鉄イオン源及びヨウ素イオン源を含有する。このように、少なくとも鉄イオン源及びヨウ素イオン源を含有する無電解ニッケルめっき浴を用いることで、有害な金属を使用することなくめっき浴の分解を抑制して、めっき浴の安定化を図ることができる。
【選択図】なし
Description
本実施の形態に係るめっき浴は、例えば、水溶性ニッケル塩と、還元剤と、錯化剤と、鉄イオン源及びヨウ素イオン源とを含有する。
Fe2+ → Fe3+ (1)
Fe3+ + I− → I + Fe2+ (2)
2H*+ I → H2 + I− (3)
続いて、非めっき処理時及びめっき処理時における本実施の形態に係るめっき浴の管理方法について説明する。上述した還元剤の酸化反応(めっき皮膜の析出又はめっき浴の分解)にはめっき液の温度が大きく依存し、非めっき処理時及びめっき処理時におけるめっき液の温度については、めっき浴の組成等によって異なるが、80〜90℃とするのが好ましい。このような温度とすることで、めっき液の蒸発が激しくなるのを防止してめっき浴の組成を所定の範囲に維持するとともに、めっき浴の分解を防止してめっき浴の安定化を図ることができる。
続いて、本実施の形態に係るめっき浴を用いためっき方法について説明する。本実施の形態に係るめっき方法では、少なくとも鉄イオン源及びヨウ素イオン源を含有する無電解ニッケルめっき浴に被めっき物を浸漬し、この被めっき物の表面に無電解ニッケルめっき皮膜を形成する。
以下、本発明の具体的な実施例について説明する。なお、本発明は、下記の実施例に限定されるものではない。
サンプル1では、下記組成の無電解ニッケルめっき液を基本浴とし、下記表1に示す硫酸鉄1mg/Lを添加し、浴量が2Lとなるように調整した。続いて、クリーナ処理及び塩酸処理で前処理した被めっき物である鉄板(プリンターシャフト、φ10mm×300mm)を、90℃のめっき浴にて、ニッケルめっき皮膜の析出速度を14μm/hrとして1dm2/Lで60分間めっき処理を施した。
(浴組成)
硫酸ニッケル 25g/L
リンゴ酸 10g/L
乳酸 15g/L
コハク酸 10g/L
次亜リン酸ナトリウム 25g/L
pH 4.6(アンモニアにて調節)
サンプル2では、硫酸鉄の代わりにヨウ化カリウム500mg/Lを添加し、さらに、めっき処理を開始してから15分毎に、ヨウ素酸カリウムを10mg/Lずつ添加した以外は、サンプル1と同様に行った。
サンプル3では、硫酸鉄を添加せず、めっき処理を開始してから15分毎に、ヨウ素酸カリウムを10mg/Lずつ添加した以外は、サンプル1と同様に行った。
サンプル4では、硫酸鉄を添加せずに、ヨウ化カリウム500mg/Lを添加した以外は、サンプル1と同様に行った。
サンプル5では、硫酸鉄とともにヨウ化カリウム500mg/Lを添加した以外は、サンプル1と同様に行った。
サンプル6では、硫酸鉄とともにヨウ化カリウム500mg/Lを添加し、めっき処理を開始してから15分毎に、ヨウ素酸カリウムを10mg/Lずつ添加した以外は、サンプル1と同様に行った。
参照例では、硫酸鉄の代わりに酢酸鉛0.5mg/Lを添加した以外は、サンプル1と同様に行った。
めっき浴の安定性は、目視でめっき液の状態を観察し、次の基準で評価した。
○:ヒータ部(一番温度が高い部分)にニッケルが析出せず、かつ、めっき液全体にニッケルの微粉末が発生せず。
△:ヒータ部にニッケルが析出。
×:めっき液全体にニッケルの微粉末が発生してめっき浴が分解。
ニッケルめっき皮膜の特性評価については、次の2点を確認した。第1に、テストピース(鋼板)のエッジ部にも均一にニッケルが析出しているかどうかを目視にて確認した。第2に、ニッケルめっき皮膜にピットが少ないかどうかを、フェロキシルテストにより確認した。フェロキシルテストとは、錆の安定度を評価するもので、試験液(フェロシアン化カリウム、フェリシアン化カリウム、塩化ナトリウムの混合水溶液)に浸したろ紙を試験面に貼り付け、腐食活性点に対応して、ろ紙に現われる青色の斑点を調べるものである。
