i think this answer may helps u
Explanation:
Corrosion is a galvanic process by which minerals decay by oxidation normally but not continually to their oxides. When opened to air, iron rusts, silver smudges, and copper and brass get a bluish-green covering known as patina. Of the different minerals subjected to corrosion, iron is the most powerful commercially. An expected $100 billion per year is used in the United States only to restore iron-containing things destroyed by corrosion. Consequently, the evolution of techniques for preserving metal exteriors from corrosion creates a very dynamic area of modern research. In the corrosion method, iron ore acts as the anode in a galvanic cell and is oxidized to Fe2+; oxygen is decreased to water at the cathode.
