Abstract

Pellicule isolante de forstérite adhérant bien à une tôle d'acier au silicium à grains orientés, dans laquelle la grosseur moyenne des grains de forstérite qui la constitue ne dépasse pas 0,7 mu m, et son procédé de formation. Le procédé de production de cette pellicule consiste à soumettre une tôle d'acier au silicium laminée à froid à diverses opérations de recuit et d'enduction ainsi qu'à l'action de diverses atmosphères de compositions appropriées. Cette pellicule est destinée à protéger une tôle d'acier au silicium des actions mineures.
