[Note Guidelines] Photographer's Note
Rust on iron really spreads out, fast.

When in contact with water and oxygen, or other strong oxidants and/or acids, iron will rust. If salt is present as, for example, in salt water, it tends to rust more quickly, as a result of the electro-chemical reactions. Iron metal is relatively unaffected by pure water or by dry oxygen.
As with other metals, a tightly adhering oxide coating, a passivation layer, protects the bulk iron from further oxidation. Thus, the conversion of the passivating iron oxide layer to rust results from the combined action of two agents, usually oxygen and water.
Other degrading solutions are sulfur dioxide in water and carbon dioxide in water. Under these corrosive conditions, iron(III) species are formed. Unlike iron(II) oxides, iron(III) oxides are not passivating because these materials do not adhere to the bulk metal. As these iron(III) compounds form and flake off from the surface, fresh iron is exposed, and the corrosion process continues until all of the iron is either consumed or all of the oxygen, water, carbon dioxide, or sulfur dioxide in the system are removed or consumed.

Ciao Thomas



You have a nice post the action of the rust,
and at the same time, a good explanatory text
of such action as it happens!
Cool idea and well your education.
I like how he can see the colors and
details on when this corrosion.
Nice post my friend ....
Greetings

Bonjour Thomas
Les détails, les couleurs de cette photo en font une bonne image abstraite qui se prêterai bien pour un agrandissement accroché dans une galerie.
Bon job.
Bonne journée.

That doesn't look so good, but yet... it does ;) thanks for the note this is a great picture. I love when people have that eye to make anything look like art. Well done sir!

Shoot on!
Eric

Bonjour Thomas,

Une chose rare sur le site, à voir de prés!!!
Et oui, la rouille se prête aussi à la photo comme tu nous le montres ici!!!
