A defect generated at a portion to be treated of a machine component is removed, a porous deposition is formed by employing a molded electrode composed of a molded body or such molded from powder of a metal or such and generating a pulsing electric discharge between a removed portion from which the defect in the machine component is removed and the molded electrode so that a material of the molded electrode or such is deposited or so at the removed portion of the machine component by energy of the electric discharge and finish machining to required dimension is carried out so as to make a thickness of the deposition to be a predetermined thickness.
L'invention concerne un procédé pour réparer une pièce de machine. Un défaut se trouvant dans une partie de la pièce de machine à réparer est extrait et une impulsion est déchargée entre la partie dont le défaut est extrait et une électrode moulée comportant un corps moulé ou analogue fait de poudre métallique ou d'un composant similaire, de sorte que le matériau de l'électrode moulée est déposé dans la partie dont le défaut est extrait au moyen de l'énergie de décharge pour former une accumulation poreuse. Ensuite, la finition dimensionnelle permet de donner une forme et une certaine épaisseur à l'accumulation poreuse.
