Abstract

L'invention concerne une plaque d'acier revêtue hautement résistante à la corrosion et son procédé de préparation. La plaque d'acier est composée d'une base en acier et d'une couche de revêtement. La microstructure de la couche de revêtement est une phase eutectique ternaire Zn-MgZn2-Al, une phase eutectoïde binaire Zn-Al, une phase eutectique binaire Zn-MgZn2, une phase eutectique ternaire Mg2Si-Zn, et une couche d'alliage Al-Zn-Fe-Si, et la composition chimique de la couche de revêtement comprend de 10 à 20 % d'Al, de 2,2 à 6 % de Mg, de 0,08 à 0,4 % de Si, et de 0,05 à 0,6 % de RE. L'acier revêtu de milieu-aluminium-zinc-aluminium-magnésium préparé par le procédé présente une meilleure résistance à la corrosion qu'une couche de revêtement de zinc-aluminium-magnésium classique. La microstructure de la couche de revêtement est régulée au moyen d'un système de composition et d'un processus de refroidissement. Ainsi, la microstructure de grains est affinée, l'apparition d'une phase de zinc pure en tant que phase faible est évitée, la résistance à la corrosion est améliorée, l'apparition de phases fragiles telles qu'une phase de terre rare et une phase riche en silicium est éliminée, et l'aptitude au formage de la couche de revêtement est optimisée ; de plus, la couche de revêtement, après avoir été pliée, présente des fissures réduites et présente encore une bonne résistance à la corrosion, et ainsi les exigences d'utilisation de l'acier photovoltaïque pendant 30 ans peuvent être satisfaites.
