Dehumidification for the aerospace industry

Corrosion of steel on a drop of water

Iron cannot rust in the mere dry air. However, when moisture settles on the metal, oxygen (O2) and water (H2O) begin to react to form hydroxide ions (OH-). To balance the electrons required for this reaction, the iron oxidizes, i.e. it releases its electrons, which are then absorbed by the oxygen. This process produces iron oxide. Where the electrons have been withdrawn, an electron shortage occurs and positively charged iron atoms (Fe2+) are released. These migrate into the water droplets and combine there with the negatively charged hydroxide ions (OH-). In the first step, iron(II) hydroxide is formed as a result of different charges. Further reactions with water, oxygen and hydroxide ions result in ever more continuous reactions from which iron(III) oxide and iron(III) hydroxide are formed. They settle on the metal surface and give the rust its typical appearance. Unlike with metals such as aluminum, the process is only stopped when iron is no longer present.
