Definition - What does Oxidation mean?
Oxidation is the reaction caused by contact between substances and oxygen molecules. Such substances may be metals or non-metals, such as living tissues.
More technically, oxidation can be defined as the loss of one electron during the phase where two or more elements interact. In this, the elements do not necessarily include oxygen. In short, it can be described as an atom’s enhanced oxidation state via a chemical reaction. It's exact opposite is called reduction, which exhibits a decrease in its oxidation state. Both reactions entail formal electron transfers. Net loss involves oxidation while net gain is the state of reduction.
Corrosionpedia explains Oxidation
In order to prevent corrosion caused by oxidation, materials can be guarded through different factory coatings. These may include:
· High-density polyethylene (HDPE)
· Fusion-bonded epoxy (FBE)
Moreover, field-applied coatings can also be utilized like those that are bitumen based, multiple- or single-layer butyl tapes, petrolatum and others. The type of coating that should be chosen depends on factors like:
· Environmental settings
· Expected substrate lifetime
· Shape, position and substrate material
· Repair and application costs
By understanding the oxidation process that can be attributed to corrosion, proper coating applications can be facilitated.
