Abstract: front page image
(EN)This aluminum-based alloy plated steel material comprises a steel material and a coating layer formed on the surface of the steel material. The coating layer contains, in mass%, 10% to 50% iron, and 3% to 15% silicon, and is provided with: an aluminum-based alloy plating layer formed on the surface of the steel material; a layer containing ZnO formed on the surface of the aluminum-based alloy plating layer; and a ZnAl2O4 layer that is formed between the aluminum-based alloy plating layer and the layer containing the ZnO, and has a thickness of 0.05 μm to 2 μm.
(FR)L'acier plaqué d'alliage d'Al de l'invention, est constitué d'un acier, et d'une couche de revêtement formée à la surface dudit acier. Ladite couche de revêtement est munie : d'une couche de placage en alliage d'Al comprenant, en % en masse, au moins 10 et au plus 50% de Fe, et au moins 3% et au plus 15% de Si, et formée à la surface dudit acier ; d'une couche contenant un ZnO formée à la surface de ladite couche de placage en alliage d'Al ; et d'une couche ZnAl2O4 formée entre ladite couche de placage en alliage d'Al et ladite couche contenant un ZnO, et possédant une épaisseur supérieure ou égale à 0,05µm et inférieure ou égale à 2µm.
(JA)Al系合金めっき鋼材は、鋼材と前記鋼材の表面に形成された被覆層とからなり、前記被複層は、質量%で10%以上50%以下のFeと、3%以上15%以下のSiとを含有し、前記鋼材の表面に形成されたAl系合金めっき層と、前記Al合金めっき層の表面に形成されたZnOを含む層と、前記Al合金めっき層と前記ZnOを含む層との間に形成され、0.05μm以上2μm以下の厚みを有するZnAl層と、を具備してなる。
