Abstract
On soumet un élément métallique manufacturé tel qu'un fil recouvert d'un film d'oxyde de magnétite à une contrainte mécanique afin de provoquer le craquage dudit film à la surface de l'élément métallique. L'élément métallique traverse ensuite un bain à cellule d'électrolyse dans lequel il forme l'anode de celui-ci, et des barres en acier placées verticalement forment l'anode. On applique un courant continu pulsé sur l'anode et la cathode. Le courant s'écoule à la surface de l'élément métallique par les fissures formées dans l'oxyde, ce qui permet de maintenir l'anode constituée par l'élément métallique dans un état de dépassivation et de désagréger la liaison entre le film d'oxyde et l'élément métallique. On enlève ensuite facilement la magnétite de l'élément métallique. On peut également utiliser une phase de contrainte thermique avant la contrainte mécanique.
