(JA) 黒色めっき鋼板
Abstract: front page image
(EN) A black-plated steel sheet has a Zn-plating layer containing molten Al and Mg, containing Al in the amount of 1.0-22.0 mass%, containing Mg in the amount of 1.3-10.0 mass%, and having a Zn black oxide distributed in a lamella pattern in the plating layer. The Zn black oxide is a Zn oxide derived from a Zn2Mg phase. The brightness of the surface of the Zn-plating layer containing the molten Al and Mg has an L* value of 60 or less.
(FR) L'invention concerne une tôle d'acier noire comportant une couche de revêtement de Zn contenant Al et Mg fondus, contenant Al dans une quantité comprise entre 1,0 et 22,0 % en masse, contenant Mg dans une quantité comprise entre 1,3 et 10,0 % en masse et comportant un oxyde de Zn noir réparti dans une configuration lamellaire de la couche de revêtement. L'oxyde de Zn noir est un oxyde de Zn dérivé d'une phase Zn2Mg. La brillance de la couche de revêtement de Zn contenant Al et Mg fondus a une valeur L* inférieure ou égale à 60.
(JA)  黒色めっき鋼板は、Al:1.0~22.0質量%、Mg:1.3~10.0質量%を含み、かつZnの黒色酸化物がめっき層中にラメラ状に分布している溶融Al、Mg含有Znめっき層を有する。Znの黒色酸化物は、ZnMg相に由来するZnの酸化物である。溶融Al、Mg含有Znめっき層表面の明度は、L値で60以下である。
