Abstract
L'invention concerne les techniques d'usinage. Un usinage électrochimique est réalisé en utilisant un courant pulsé, comprenant seulement des alternances positives séparées par des intervalles sans courant, dans un électrolyte de type passivant contenant de préférence de l'ordre de 30 à 50 grammes par litre de nitrate de sodium. Application à l'usinage électrochimique des aciers.
