Abstract

Corrosion is the degradation of a material, often a metal, resulting from a chemical or an electrochemical reaction with its environment. These irreversible processes lead to changes in the metal properties (including optical properties related to aesthetics such as lustre, colour etc.) and, depending on their nature and extent, they may result in a significant loss of material. Some metals are chemically more reactive in burial, indoor and outdoor environments. For example, copper and iron corrode more easily than silver and gold; this is the main reason for the latter being called noble metals
