METHOD FOR THE ANTICORROSIVE TREATMENT OF HOLLOW BODIES, METHOD FOR PRODUCING A METALLIC STRUCTURE TREATED ACCORDING TO SAID METHOD, AND METHOD FOR MAINTAINING THE STRUCTURE

摘要

According to the invention, a hollow body with a surface (18) which is difficult to access and is to be preserved from corrosion is treated by injecting an alveolar foam supported by an anticorrosive agent thereinto. A metallic structure (10) is produced by assembling the structure (10) and then treating the surfaces (18) of the structure (10) that are difficult to access with anticorrosive protection treatment. The invention can be applied to railway carriages.
