Abstract

L'invention concerne un procédé de traitement de surface d'une pièce mécanique (38) réalisée dans un matériau conducteur, ladite pièce mécanique (38) présentant une surface à traiter (40), ledit procédé de traitement étant destiné à augmenter le coefficient d'adhérence de la surface traitée. Le procédé comprend les étapes suivantes : on fournit un outil (14) présentant une surface de travail (20) ; on forme des alvéoles (34) dans ladite surface de travail (20), lesdites alvéoles (34) définissant des parties en creux et des parties en relief ; on agence ledit outil (14) et ladite pièce mécanique (38) de façon à porter ladite surface de travail (20) dudit outil en regard de ladite surface à traiter (40) ; et, on entraîne ledit outil (14) en translation vers ladite pièce mécanique (38) selon un mouvement périodique et on applique une différence de potentielle entre ladite pièce mécanique (38) et ledit outil (14), tandis qu'on injecte un électrolyte entre la dite surface à traiter (40) et ladite surface de travail (20), de manière à extraire le matériau situé en regard desdites parties en relief pour former des aspérités (44) en regard desdites parties en creux (34).The invention relates to a method for treating the surface of a mechanical part (38) made of a conductive material, said mechanical part (38) having a surface to be treated (40), said treatment method being intended to increase the coefficient d adhesion of the treated surface. The method comprises the following steps: providing a tool (14) having a work surface (20); cells (34) are formed in said work surface (20), said cells (34) defining recessed portions and raised portions; said tool (14) and said mechanical part (38) are arranged so as to bear said working surface (20) of said tool facing said surface to be treated (40); and, said tool (14) is driven in translation towards said mechanical part (38) according to a periodic movement and a potential difference is applied between said mechanical part (38) and said tool (14), while an electrolyte is injected between said surface to be treated (40) and said work surface (20), so as to extract the material located opposite said raised parts to form asperities (44) opposite said recessed parts (34).
