Two types of protective treatments: microcrystalline wax (Cosmolloïd wax) and decanoate solution (HC10) were tested. Two aspects were considered: the penetration of the treatments in the corrosion layers, and its durability. Equivalent efficiencies for both treatments were demonstrated. The penetration of the treatments seems to depend essentially on its application mode. Re-corrosion experiments of treated samples under immersion in D2O demonstrate that the efficiency and the durability with time or after water leaching depend on the penetration of the treatments in the corrosion layers. %G English %2 https://cea.hal.science/cea-03159604/document %2 https://cea.hal.science/cea-03159604/file/PubliCarbox_APCHAIN_2021.pdf %L cea-03159604 %U https://cea.hal.science/cea-03159604 %~ CEA %~ UNIV-ARTOIS %~ CNRS %~ UNIV-BM %~ UNIV-ORLEANS %~ UNIV-CERGY %~ UNIV-BM-THESE %~ FSP-PATRIMA %~ PUBNIMBE %~ INC-CNRS %~ IRAMIS-NIMBE %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ UNIV-LILLE %~ UNIV-BORDEAUX-MONTAIGNE %~ INRAE %~ TEST-HALCNRS %~ UNIVERSITE-PARIS-SACLAY %~ I-MAT %~ L2MGC %~ CY-TECH-SE %~ ANR %~ GS-ENGINEERING %~ IRAMIS %~ GS-CHIMIE %~ GS-HUMANITIES-HERITAGE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ TEST2-HALCNRS %~ RESEAU-EAU
