Abstract

Un procédé de décapage d'un matériau isolant comportant notamment des couches d'oxydes à sa surface, caractérisé en ce que l'on applique sur la surface à décaper (1) une première électrode (4) constituée par un tampon de laine métallique (6) ainsi qu'un électrolyte (3) dans lequel plonge également une deuxième électrode (9) et l'on maintient entre les deux électrodes (4 et 9) une tension et une intensité telles que le première électrode (4) soit polarisée cathodiquement en provoquant un dégagement d'hydrogène.
