Detailed explanation-1: -The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion. Cossorion, in general, is a process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides.

Detailed explanation-2: -Corrosion is when a refined metal is naturally converted to a more stable form such as its oxide, hydroxide or sulphide state this leads to deterioration of the material.

Detailed explanation-3: -Erosion corrosion can easily occur in the case of soft metals or where a protective layer on the metal surface is damaged. Erosion corrosion invariably occurs in the form of intensified general corrosion. Solid particles or air bubbles in liquids are particularly destructive in the erosion corrosion process.

Detailed explanation-4: -Metal corrosion, also known as oxidation, occurs when an ionic chemical reaction meets the presence of oxygen on a metal’s surface. The oxidation process takes place in the air while metal is simultaneously exposed to water or to acids.
