Corrosion

The gradual destruction of material, usually metals, by chemical reaction with its environment. In the most common use of the word, this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion.

Purpose

Understanding corrosion is vital for maintaining the integrity and longevity of structures and components made from metals. Preventing or mitigating corrosion ensures safety, reduces maintenance costs, and extends the lifespan of metal products and infrastructure.

Examples of Use

1. Applying anti-corrosion coatings to steel bridges to prevent rusting and extend their lifespan.
2. Using corrosion-resistant materials like stainless steel in the construction of chemical plants to avoid damage from harsh environments.

Related Terms

• Rust: The red or orange coating formed on iron or steel by oxidation, especially in the presence of moisture.
• Galvanization: The process of applying a protective zinc coating to steel or iron to prevent rusting.
• Oxidation: A chemical reaction in which a material loses electrons, often resulting in corrosion when metals are involved.

Notes

Preventative measures against corrosion include using corrosion-resistant materials, applying protective coatings, and implementing cathodic protection systems. Regular inspections and maintenance are crucial in managing corrosion.
