Abstract
【解決手段】金属からなる部材101と、部材101の表面に形成された溶融亜鉛めっき層102とを備える。溶融亜鉛めっき層102は、水に対する溶解度が硫酸カルシウムより高い硫酸塩を含有している。溶融亜鉛めっき層102における硫酸塩の含有量は、亜鉛100gに対して0.008〜0.133molとされていればよい。溶融亜鉛めっき層102に含有している硫酸塩は、硫酸カリウム、硫酸ナトリウム、硫酸マグネシウム、硫酸カルシウム、硫酸第二鉄、硫酸第一鉄、硫酸リチウム、硫酸カルシウム、硫酸アルミニウムの少なくとも1つであればよい。

Description
はじめに、実験1について説明する。
「JIS H 8641」の規格に示されている蒸留亜鉛による亜鉛浴(めっき浴)を用い、この亜鉛浴に硫酸塩の粉末を分散させ、鋼板に溶融亜鉛めっきを施して実験1の試料とした。
・めっき試料2は、亜鉛100に対して硫酸マグネシウム粉末を1の重量比で混合・分散させて作製した亜鉛浴でめっきした試料である。
・めっき試料3は、亜鉛100に対して硫酸マグネシウム粉末を2の重量比で混合・分散させて作製した亜鉛浴でめっきした試料である。
・めっき試料4は、亜鉛100に対して硫酸マグネシウム粉末を4の重量比で混合・分散させて作製した亜鉛浴でめっきした試料である。
・めっき試料5は、亜鉛100に対して硫酸マグネシウム粉末を8の重量比で混合・分散させて作製した亜鉛浴でめっきした試料である。
・めっき試料6は、亜鉛100に対して硫酸マグネシウム粉末を16の重量比で混合・分散させて作製した亜鉛浴でめっきした試料である。
実験1の実験結果を以下の表1に示す。表1において、「添加量」は、亜鉛100gに対する硫酸マグネシウムの重量比である。硫酸マグネシウム無添加の亜鉛めっきと比較すると、硫酸マグネシウムを添加した溶融亜鉛めっき層は、腐食減量が約15〜34%減少した。
次に、実験2について説明する。
実験1で用いた硫酸マグネシウムを、実験2では硫酸ナトリウムに変更し、硫酸ナトリウムの粉末を、蒸留亜鉛による亜鉛浴に分散させ、実験1と同様の鋼板に溶融亜鉛めっきを施して実験2の試料とした。
以下、実験2の実験結果2について説明する。実験1のめっき試料4と同様に、亜鉛100に対して、硫酸ナトリウム粉末を4.73の重量比で混合した亜鉛浴で溶融亜鉛めっきを施しためっき試料7の腐食減量は11.0g/m2)であった。めっき試料4の場合(腐食減量9.3g/m2)と比較すると、硫酸マグネシウムを用いためっき試料4の方が腐食減量が少ない(腐食速度が低い)が、硫酸ナトリウムを用いためっき試料7においても、無添加の場合(めっき試料1)と比較して、腐食減量が低下した。
