Description
上記亜鉛合金めっき層は、重量%で、Al:8~25%、Mg:4~12%、残りはZn及び不可避不純物を含み、
上記亜鉛合金めっき層の表面で観察される多角形凝固相が占める面積分率は、20~90%である耐食性及び表面品質に優れた亜鉛合金めっき鋼材を提供する。
上記用意された素地鉄を重量%で、Al:8~25%、Mg:4~12%、残りはZn及び不可避不純物を含むめっき浴に浸漬してめっきする段階;
上記めっきされた素地鉄をワイピングする段階;及び
上記ワイピング後、溶融亜鉛めっき層の表面に多角形凝固相を形成する段階を含む耐食性及び表面品質に優れた亜鉛合金めっき鋼材の製造方法を提供する。
上記Alは、溶湯の製造時にMg成分を安定化し、腐食環境での初期腐食を抑制する腐食障壁役割を果たすものであって、Mg含有量に応じてAl含有量が異なることができる。上記Al含有量が8%未満であると、溶湯の製造時にMgを安定化することができず、溶湯表面にMg酸化物が生成されて使用が困難になる。一方、25%を超える場合には、めっき温度の上昇及びめっき浴中に設けられる各種設備の溶食が過度に発生するため、好ましくない。
上記Mgは、耐食性を発現する組織を形成する主成分であって、上記Mgが4%未満であると、耐食性の発現が十分でなく、12%を超える場合には、Mg酸化物が多量に形成される問題があって、2次的に材質劣化と費用上昇などの様々な問題を引き起こす可能性があるため、上記Mgは4~12%含むことが好ましい。より好ましくは、上記Mgは5%以上含むことができる。
