CA 2584449

The invention relates to a hot-dip coating method in a liquid bath of zinc, comprising aluminium, for a strip of running austenitic iron/carbon/manganese steel, whereby said strip is subjected to a thermal treatment in an oven within which a reducing atmosphere with relation to iron is present, to give a strip covered with a thin layer of manganese oxide, said strip covered with the thin layer of manganese oxide is then run through said bath, the content of aluminium of which is adjusted to give a value at least equal to the content necessary such that the aluminium completely reduces the layer of manganese oxide such as to form a coating on the surface of the strip, comprising a layer of iron/manganese/zinc alloy and an outer layer of zinc.

L'invention a pour objet un procédé de revêtement au trempé à chaud dans un bain liquide à base de zinc comprenant de l'aluminium, d'une bande en acier austénitique fer-carbone-manganèse en défilement, selon lequel on fait subir à ladite bande un traitement thermique dans un four à l'intérieur duquel règne une atmosphère réductrice vis à vis du fer, pour obtenir une bande couverte d'une mince couche d'oxyde de manganèse, puis on fait défiler la bande couverte de la mince couche d'oxyde de manganèse dans ledit bain, la teneur en aluminium dans le bain étant ajustée à une valeur au moins égale à la teneur nécessaire pour que l'aluminium réduise complètement la couche d'oxyde de manganèse, de manière à former à la surface de la bande un revêtement comprenant une couche d'alliage fer-manganèse-zinc et une couche superficielle de zinc.
