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

The invention involves the treatment of a hollow body having a difficult-to-access surface ( 18 ) to be preserved from corrosion by injecting a cellular foam supporting an anti-corrosion agent into the hollow body. Also involved is the production of a metal structure ( 10 ) by assembling the structure ( 10 ) and then applying an anti-corrosion treatment to the difficult-to-access surfaces ( 18 ) of the structure ( 10 ). The invention is particularly applicable to railway wagons.
