A Review on Corrosion of Metals and its Control

Abstract

Corrosion is the degradation and loss of a material's key qualities as a result of chemical, electrochemical, and other processes between the exposed material surface and the environment. Corrosion of metals and nonmetals occurs as a result of gradual environmental interaction on the surface of the material. This interaction has an impact on the structures and capabilities of many materials. The presence of moisture and oxygen in the ambient air can initiate the rusting process on steel surfaces. Corrosion is a hazardous and expensive condition. Buildings and bridges can collapse as a result of it, oil pipelines can burst, chemical facilities can leak, and restrooms can flood. Corroded electrical contacts can create fires and other issues, corroded medical implants can cause blood poisoning, and air pollution has corroded works of art all around the world. The safe disposal of radioactive waste that must be held in containers for tens of thousands of years is jeopardized by corrosion. India loses around 5–7 per cent of its Gross Domestic Product (GDP) every year due to corrosion. Furthermore, rust not only raises component costs, but it also causes life losses and safety hazards. As a result, we shall cover the many types of corrosion and how to prevent them in this paper.
