Corrosion starts at the surface of a material and moves inward.\n\n2. The dissolution and wearing away of metal caused by a chemical reaction such as between water and the pipes, chemicals touching a metal surface, or contact between two metals.\n\n3. Action or effect of eating away gradually. This can occur through oxidation, the action of strong acids, or caustic alkali.",
