Metals and corrosion
WebCorrosion is defined as ‘an irreversible interfacial reaction of a material (metal, ceramic, polymer) with its environment which results in consumption of the material or in dissolution into the material of a component of the environment’ (IUPAC, 2012). From: Understanding Biocorrosion, 2014. Add to Mendeley. WebCorrosion happens when a metal continues to oxidise. The metal becomes weaker over time, and eventually all of it may become metal oxide.
