Iron combines with oxygen to for RUST, not dust.
Iron combines with oxygen in the presence of water to form rust. Rust is a chemical compound known as iron oxide, specifically Fe2O3 or Fe3O4, which is a reddish-brown substance that forms on the surface of iron or steel when exposed to oxygen and moisture.
Iron. Rust is called Iron oxide and has the chemical formulae of Fe2O3·nH2O and for iron(III) oxide-hydroxide: FeO(OH)·Fe(OH)3.
Rusting is a reaction which combines molecules to form other molecules : metal +oxygen=rust

They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.

Iron does rust in the artificial sites because it combines with atmospheric oxygen to form oxides.
Water combines with oxygen to form rust. It is not reacting with water, the water serves as a catalyst.
Rust is formed when oxygen combines with metal that is untreated with items that keep the metal looking young and new.
Iron combines chemically with oxygen to form two forms of rust, ferrous oxide and ferric oxide.
The chemical change in which a substance combines with oxygen, such as the formation of iron rust, is called oxidation. This process occurs when iron reacts with oxygen in the presence of moisture to form iron oxide, which is the red-brown substance known as rust.
