…In recent years, thinner, more corrosion-resistant alloy plating of zinc-nickel Zn-Ni, zinc-iron Zn-Fe, zinc-cobalt Zn-Co, etc., with a thickness of 5 μm or less, has been commercialized. When zinc solidifies, crystal patterns called spangles are produced, and to enlarge these and give them a glossy finish, small amounts of tin or antimony are sometimes added to the zinc bath. There are theories that the origin of the word "totan" comes from the Portuguese word tutanaga, which means an alloy of zinc and copper, or tŏtan, which means "a kind of white metal." … *Some of the terminology explanations that refer to "hanamon" are listed below.

…近年はより薄くて耐食性の優れた亜鉛‐ニッケルZn‐Ni,亜鉛‐鉄Zn‐Fe,亜鉛‐コバルトZn‐Coなどの合金めっきが5μm以下の厚みで施されたものが商品化されている。亜鉛が凝固するときスパングル(華紋)といわれる結晶模様が生成されるが,これを大きくし,また光沢を与えるために,スズあるいはアンチモンを少量亜鉛浴に添加することがある。 〈トタン〉の語源としては,ポルトガル語で亜鉛と銅の合金を意味するtutanaga,あるいは〈白い金属の一種〉を意味するtŏtanに由来するとの説がある。… ※「華紋」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
