Abstract
L'invention concerne une tôle d'acier galvanisé à chaud pour automobiles, une tôle d'acier allié galvanisé à chaud, et leur procédé de production. Cette tôle d'acier galvanisé présente une quantité réduite de défauts par suite d'un placage défectueux, ainsi que d'excellentes caractéristiques d'adhérence de dépôt par contact, et est caractérisée en ce qu'elle possède des oxydes de métaux plus oxydables que le fer situé au-dessous du placage, ces oxydes étant formés lors du laminage à chaud. Selon le procédé de production, la température d'enroulement lors du laminage à chaud est égale ou supérieure à 600 DEG C, le refroidissement s'effectue à une vitesse faible, et les oxydes demeurent intacts également dans les étapes ultérieures.
