Summary[edit]
DescriptionCorrosion atmosphérique d'un clou - Atmospheric corrosion of a nail.jpg |
Français : Corrosion atmosphérique d'un clou (longueur 60 mm, diamètre original 3 mm), après ~20 ans d'exposition à l'atmosphère humide dans un toit. Noter la différence entre la zone de tête et celle de la pointe, cette dernière étant dans un environnement moins agressif et donc peu attaquée. English: Atmospheric corrosion of a nail (length 60 mm, original diameter 3 mm), after ~20 years of exposure to damp atmosphere in a roof. Note the difference between the head zone and that of the tip, the latter being in a less aggressive environnement and thus having undergone little degradation. Deutsch: Atmosphärische Korrosion an einem Nagels (Länge 60 mm, Durchmesser ursprünglich 3 mm), nach ~20 Jahren Aussetzung zu Feuchter Atmosphäre in einem Dach. Unterschied zwischen Kopf- und Spitzenseite bemerken: Die letzte wurde einer relativ wenigen aggressiven Umgebung ausgesetzt, und so wenig beschädigt. |
