Corrosion is the process of material deterioration, primarily involving the degradation of metals through chemical reaction with their surrounding environment. At its core, it is an electrochemical process that requires an anode (where oxidation occurs, meaning the loss of electrons) and a cathode (where reduction occurs). The rate and mechanism of corrosion are highly dependent on environmental factors such as temperature, pH, and the presence of dissolved oxygen or other electrolytes. Understanding these principles allows for the development of protective techniques, including cathodic protection and the application of inert coatings, which aim to disrupt the electrochemical circuit and slow or prevent the destructive chemical reaction.
