Abstract

L'invention concerne un procédé de traitement d'une pièce (1) pour réduire sa porosité, pièce obtenue notamment par un procédé de fonderie. Le procédé comporte les étapes de : - remplissage d'une cuve (3) d'un liquide, - positionnement de la pièce (1) dans la cuve (3) de sorte à l'immerger dans ledit liquide, - positionnement, dans le liquide, d'une électrode (4) en vis-à-vis d'une surface (11) de ladite pièce, à une distance d prédéfinie, ladite électrode étant reliée à un générateur d'impulsions électriques (5), - génération, par le générateur d'impulsions électriques (5), d'une décharge électrique dans le liquide, entre l'électrode (4) et la pièce (1), créant une onde de choc (8) depuis la surface (11) de la pièce (1) et qui se propage dans l'épaisseur (e) de ladite pièce.
