Abstract: front page image
(EN) Disclosed are a zinc alloy plated steel and a method for manufacturing same, the zinc alloy plated steel comprising: a base iron; a Zn plated layer formed on top of the base iron; and a Zn-Mg alloy layer formed on top of the Zn plated layer and obtained through mutual diffusion of Zn and Mg, wherein the ratio of the weight of Mg contained in the Zn-Mg alloy layer with respect to the total weight of the Zn plated layer and the Zn-Mg alloy layer is 0.13 to 0.24, and the sum of the adhesion quantity of the Zn layer and the Zn-Mg alloy layer is no more than 40g/m2 (more than 0g/m2).
(FR) L'invention concerne un acier plaqué d'alliage de zinc et son procédé de fabrication, l'acier plaqué d'alliage de zinc comprenant : un fer de base ; une couche plaquée de Zn formée sur la partie supérieure du fer de base ; une couche d'alliage Zn-Mg formée au-dessus de la couche plaquée de Zn et obtenue par diffusion réciproque de Zn et de Mg, le rapport du poids de Mg contenu dans la couche d'alliage Zn-Mg par rapport au poids total de la couche plaquée de Zn et de la couche d'alliage de Zn-Mg étant de 0,13 à 0,24, et la somme de la quantité d'adhérence de la couche de Zn et de la couche d'alliage Zn-Mg n'étant pas supérieure à 40g/m2 (plus de 0g/m2).
(KO) 소지철, 상기 소지철 상에 형성된 Zn 도금층, 및 상기 Zn 도금층 상에 형성되고, Zn 및 Mg의 상호 확산에 의해 얻어진 Zn-Mg 합금층을 포함하고, 상기 Zn 도금층 및 Zn-Mg 합금층의 총 중량에 대한 상기 Zn-Mg 합금층에 함유된 Mg 중량의 비는 0.13 내지 0.24이고, 상기 Zn 도금층 및 Zn-Mg 합금층의 부착량의 합은 40g/m2 이하(0g/m2 제외)인 아연합금도금강재와 이를 제조하는 방법이 개시된다.
