Abstract: front page image
(EN)Zn alloy plated steel material having excellent weldability and processed-part corrosion resistance and a method for production of Zn alloy plated steel material are provided. In the Zn alloy plated steel material comprising base steel material and a Zn alloy plating layer, the Zn alloy plating layer includes, by wt%, Al: 0.1-5.0%, Mg: 0.1-5.0%, as well as a remainder of Zn and inevitable impurities. The Zn alloy plated steel material includes a lower interface layer and an upper interface layer between the base steel material and the Zn alloy plating layer, wherein the lower interface layer is formed on the base steel material and has a dense structure, and the upper interface layer is formed on the lower interface layer and has a network-type or island-type structure.
(FR)La présente invention concerne un acier plaqué d'alliage de zinc et son procédé de fabrication, l'acier plaqué d'alliage de zinc comprenant une fonte de base et une couche plaquée d'alliage de zinc, la couche plaquée d'alliage de zinc comprenant, en % en poids, une teneur en Al située dans la plage allant de 0,1 à 5,0 %, une teneur en Mg située dans la plage allant de 0,1 à 5,0 %, le reste étant constitué par du Zn et des impuretés inévitables, et la partie entre la fonte de base et la couche plaquée d'alliage de zinc comprenant une couche d'interface inférieure et une couche d'interface supérieure, la couche d'interface inférieure étant formée sur la fonte de base et présentant une structure dense, et la couche d'interface supérieure étant formée sur la couche d'interface inférieure et présentant une structure de type en îlot ou en réseau.
(KO)소지철과 아연합금도금층을 포함하는 아연합금도금강재에 있어서, 상기 아연합금도금층은 중량%로, Al: 0.1~5.0%, Mg: 0.1~5.0%, 잔부 Zn 및 불가피한 불순물을 포함하고, 상기 소지철과 상기 아연합금도금층의 사이에는, 상기 소지철 상에 형성되고 치밀한 구조를 가지는 하부 계면층; 및 상기 하부 계면층 상에 형성되고, 네트워크(network)형 또는 아일랜드(island)형 구조를 가지는 상부 계면층을 포함하는 아연합금도금강재와 이를 제조하는 방법이 개시된다.
