Abstract
Description
Alは、めっき鋼材の製造過程においてめっき浴内のドロスを抑制する役割を果たす。一方、一般に、Alは、素地鉄と溶融亜鉛系めっき層の界面にFe−Al系合金相を形成し、めっき性を向上させる役割を果たすと広く知られているが、本発明では、Fe−Al系合金相ではなく、Zn−Fe−Mn系合金相を形成させることを目標とするため、その含有量をやや少なく管理する必要性があり、0.5%以下に限定する。但し、その含有量が少なすぎる場合には、めっき浴内のドロスの抑制効果が十分でないおそれがあるだけでなく、Zn−Fe−Mn系合金相が過度に形成されて加工性が劣化する可能性がある。また、Alは、Feと反応して抑制層を形成するが、Al含有量が少なすぎる場合には、Feの拡散が増加しすぎることがある。その結果、拡散したFeとの反応が増加することになって合金層が過度になることもある。したがって、これを考慮して、その下限を0.01%に限定する。本発明の一実施形態によると、上記Al含有量は0.08〜0.15%で決めることができる。
Mgは、めっき鋼材の耐食性向上に重要な役割を果たす元素であって、めっき層の内部に含有されたMgは厳しい腐食環境下で耐食性向上効果が少ない酸化亜鉛系腐食生成物の生成を抑制し、耐食性の向上効果が大きい亜鉛水酸化物系腐食生成物をめっき層の表面で安定化させる役割を果たす。本発明では、かかる効果を得るために、0.01%以上含まれることが好ましい。但し、その含有量が多すぎる場合には、めっき鋼材の製造過程においてめっき浴の表面にMg酸化性ドロスが大量に形成され、ドロス欠陥が生じるという問題が発生することがある。これを考慮して、その上限を1.5%に限定する。本発明の一実施形態によると、上記Mg含有量は、0.08〜0.15%で決めることができる。本発明の一実施形態によると、上記Mg含有量とAl含有量の割合は、0.8:1〜1.2:1であることができる(%Mg:%Al)。
Mnは、溶融亜鉛系めっき層の硬度を増加させることでプレス加工性を向上させる役割を果たす。一方、めっき層にMgが単独で添加される場合には、Fe−Zn反応が抑制されるようになるが、適量のMnがともに添加される場合には、Fe−Zn合金化が促進され、Feの一部がMnで置換されて素地鉄と溶融亜鉛系めっき層の界面にZn−Fe−Mn系合金相が形成されるようになる。このように素地鉄と溶融亜鉛系めっき層の界面にFe−Al系合金相ではなく、Zn−Fe−Mn系合金相が形成される場合には、めっき鋼材の溶接性が大幅に向上するようになる。本発明では、かかる効果を得るために、0.05%以上含まれることが好ましい。但し、その含有量が多すぎる場合には、めっき鋼材の耐食性が劣化する可能性がある。したがって、本発明では、その上限を1.5%に限定する。本発明の一実施形態によると、上記Mn含有量は、0.1〜0.5%であることができる。
Feは、めっき鋼材の製造過程で必然的に流入される元素であって、その含有量が少なすぎる場合には、Zn−Fe−Mn系合金相の形成が抑制され、溶接性が劣化することがある。これに対し、その含有量が多すぎる場合には、大量のZn−Fe−Mn系合金相の形成により、加工においてめっき層が脱落するという問題を誘発する可能性がある。これを考慮して、Fe含有量は、0.1〜6%に限定する。本発明の一実施形態によると、上記Fe含有量は、0.5〜3%で決めることができる。一実装形態によると、上記Feは、素地鋼板からめっき層に拡散するようにして含まれることもできる。
めっき用試験片として厚さ0.8mm、幅100mm、長さ200mmの低炭素冷延鋼板(C:0.0018重量%、P:0.01重量%、Mn:0.7重量%、Ti:0.02重量%、Nb:0.02重量%、Al:0.03重量%)を素地鉄として設けた後、上記素地鉄をアセトンに浸漬し、超音波洗浄して表面に存在する圧延油などの異物を除去した。めっきを行う前に、すべての試験片は、一般の溶融めっき現場で鋼板の機械的特性を確保するために行う750℃での還元雰囲気熱処理過程を経た。その後、素地鉄を下記表1の組成を有するめっき浴に浸漬してめっきする。このとき、めっき条件は、めっき浴の温度及びめっき浴に浸漬される素地鉄温度を除いては、すべての例において同一に処理し、めっき浴の温度はAl含有量による融点の上昇を考慮して、440〜600℃に調節した。めっき浴に浸漬される素地鉄の温度は下記表1にともに示した。めっき完了後に、N2ガスワイピングを用いて、片面めっき付着量が70g/m2になるように調節して冷却した。また、めっき層の温度が460〜400℃の温度区間では、めっき層の冷却速度を1.5℃/秒に制御し、後の400℃から300℃までの冷却速度は10℃/秒にした。
