Abstract
Description
ここで、Xは0<X<1の実数、nは0≦n≦10の実数である。
亜鉛系めっき鋼板を、0.3g/L以上の硫酸イオンを含有する酸性溶液に接触させた後1〜60秒間保持し、その後水洗を行う酸化物層形成工程と、前記酸化物層形成工程で形成された酸化物層の表面を、pHが9〜12のアルカリ性水溶液に接触させた状態で0.5秒以上保持し、その後水洗、乾燥を行う中和処理工程と、を備え、前記アルカリ性水溶液は炭酸イオンを0.1g/L以上含有することを特徴とする亜鉛系めっき鋼板の製造方法。
酸化物層の厚さの測定
合金化溶融亜鉛めっき鋼板に形成された酸化物層の厚さの測定には蛍光X線分析装置を使用した。測定時の管球(tube bulb)の電圧および電流は30kVおよび100mAとし、分光結晶(dispersive crystal)はTAPに設定してO−Kα線を検出した。O−Kα線の測定に際しては、そのピーク位置に加えてバックグラウンド位置での強度も測定し、O−Kα線の正味の強度が算出できるようにした。なお、ピーク位置およびバックグラウンド位置での積分時間は、それぞれ20秒とした。
重クロム酸アンモニウム2%+アンモニア水14%溶液(%は質量%を意味する)を用いて、酸化物層のみを溶解し、その溶液を、ICP発光分析装置を用いて、Zn、Sの定量分析を実施した。
同様に粉末化し採取した皮膜成分、ガスクロマトブラフ質量分析を用いて分析しCの存在形態について分析を実施した。
X線光電子分光装置を用いて、Zn、S、Oの存在形態について分析した。Al Ka モノクロ線源を使用し、Zn LMM, S 2pに相当するスペクトルのナロースキャン測定(narrow scan measurement)を実施した。
示差熱天秤を用いて100℃以下の重量減少量を測定した。測定には粉末試料は約15mgを用いた。試料を装置内に導入後、室温(約25℃)から1000℃まで、昇温速度10℃/minで昇温させ、昇温時の熱重量変化を記録した。
同様に粉末化し採取した皮膜成分のX線回折を実施し、結晶構造を推定した。ターゲットにはCuを用い、加速電圧40kV、管電流(tube current)50mA、スキャン速度4deg/min、スキャン範囲2〜90°の条件で測定を実施した。
プレス成形性を評価するために、各供試材の摩擦係数を以下のようにして測定した。
図1は、摩擦係数測定装置を示す概略正面図である。同図に示すように、供試材から採取した摩擦係数測定用試料1が試料台2に固定され、試料台2は、水平移動可能なスライドテーブル3の上面に固定されている。スライドテーブル3の下面には、これに接したローラ4を有する上下動可能なスライドテーブル支持台5が設けられ、これを押上げることにより、ビード6による摩擦係数測定用試料1への押付荷重Nを測定するための第1ロードセル7が、スライドテーブル支持台5に取付けられている。上記押し付け力を作用させた状態でスライドテーブル3を水平方向へ移動させることで生じる摺動抵抗力Fを測定するための第2ロードセル8が、スライドテーブル3の一方の端部に取付けられている。なお、潤滑油として、スギムラ化学工業(株)製のプレス用洗浄油プレトンR352L(Sugimura Chemical Industrial Co.,Ltd. Wash Oil for Press Forming PRETON R352L)を試料1の表面に塗布して試験を行った。
[条件1]
図2に示すビードを用い、押し付け荷重N:400kgf、試料の引き抜き速度(スライドテーブル3の水平移動速度):100cm/minとした。
[条件2]
図3に示すビードを用い、押し付け荷重N:400kgf、試料の引き抜き速度(スライドテーブル3の水平移動速度):20cm/minとした。
プレス成形シミュレーションを行った結果、面圧が7MPa以下で摺動速度が50mm/min以下の部位(張り出し成形部位など)においては、動摩擦係数より、静止摩擦係数のほうが、実際のプレス成形性との相関性が高いことが明らかになった。そこで、プレス成形性(特に張り出し部における成形性)を評価するために、各供試材の静止摩擦係数を以下のようにして測定した。図4は、試験装置10を用いた静止摩擦係数測定装置を示す概略図である。同図に示すように、供試材から採取した動摩擦係数測定用試料100を一定荷重P=370kgfで金型11、12を押し付けてから10mm/minの速度で、金型11、12で侠持されているサンプル100を引き抜く。これにより、一定荷重Pとサンプル100の引き抜きに必要な荷重Fを0.005Hzの間隔で測定した。静止摩擦係数μは、式:μ=F’/Pで算出し、摺動開始後のピーク値の摩擦係数を静止摩擦係数として取得した。なお、金型11の形状は幅35mm、試料の摺動方向長さ14mm、摺動方向両端の下部は曲率2mmRの曲面で構成され、試料が押し付けられるビード下面は幅35mm、摺動方向長さ10mmの平面を有する。金型12の形状は幅35mm、試料の摺動方向長さ24mm、摺動方向両端の下部は曲率2mmRの曲面で構成され、試料が押し付けられるビード下面は幅35mm、摺動方向長さ20mmの平面を有する(以下条件3)。なお、潤滑油として、スギムラ化学社製のプレス用洗浄油プレトン(登録商標)R352Lを試料100の表面に塗布して試験を行った。
脱脂性の評価は、脱脂後の水濡れ率で行った。作成した試験片に、スギムラ化学工業(株)製のプレス用洗浄油プレトンR352Lを片面2.0g/m2塗油したのち、日本パーカライジング(株)製(NIHON PARKERIZING CO.,LTD.)のFC−L4460のアルカリ脱脂液を用いてサンプルの脱脂を行った。脱脂液にスギムラ化学工業(株)製のプレス用洗浄油プレトンR352Lを10g/Lを予め添加することで自動車生産ラインにおけるアルカリ脱脂液の劣化をシミュレートした。ここで、脱脂時間は60秒とし、温度は37℃とした。脱脂時は、直径10cmのプロペラを用いて150rpmの速度で脱脂液を攪拌した。脱脂完了から20秒後の試験片の水濡れ率を測定することで、脱脂性の評価を行った。
外観ムラは目視により評価した。図5に示す外観見本を基準として、評点を1〜5点を付与し評価した。なお4点以上が良好であることを示し、5点は更に良好であることを示している。
評点1:面積率が50%以上の明確なムラが存在する。
評点2:面積率が50%以上であるが、ムラは明確ではない。
評点3:面積率が20%以上の明確なムラが存在する。
評点4:面積率が20以上であるが、明確ではないムラが存在する。
評点5:目視で確認できるムラは存在しない。
