Abstract

L'invention concerne un procédé de fabrication d'une couche de protection sur une pièce métallique à traiter au moyen d'un processus de traitement électrochimique. Une tension est appliquée entre au moins une électrode (12, 14) et au moins une partie de la pièce (10), ladite tension produisant une couche de passivation non électroconductrice (20) sur la surface de la pièce en fonction de la composition métallique de la ou des parties de la pièce (10), dans cette partie, au moyen d'un électrolyte (16). L'invention concerne également un composant d'une turbine à gaz ou d'un compresseur haute pression ou basse pression.
