Abstract

Procédé de traitement et de prévention de la corrosion d'un assemblage comprenant au moins deux tôles fixées à plat les unes sur les autres, dont une tôle primaire (11) et une tôle secondaire (12) constituant chacune une paroi extérieure dudit assemblage. Ce procédé est caractérisé en ce qu'il comprend les étapes suivantes :

  • a) réalisation d'au moins un passage débouchant de part et d'autre de la tôle sur au moins une des tôles de l'assemblage dont une de celles constituant les parois extérieures de cet assemblage ;
  • b) injection par l'intermédiaire d'au moins un passage débouchant réalisé sur la tôle primaire ou sur la tôle secondaire d'au moins un produit pour lutter contre la corrosion ;
  • c) obturation de l'ensemble des passages débouchant réalisés sur les tôles primaire et secondaire.

    Method for treating and preventing corrosion of an assembly comprising at least two sheets fixed flat one on top of the other, including a primary sheet (11) and a secondary sheet (12) each constituting an outer wall of said assembly. This process is characterized in that it comprises the following stages:
  • a) production of at least one passage opening out on either side of the sheet on at least one of the sheets of the assembly, one of which constitutes the outer walls of this assembly;
  • b) injection via at least one through passage made on the primary sheet or on the secondary sheet of at least one product to fight against corrosion;
  • c) sealing of all of the through passages made on the primary and secondary sheets.
