WebApr 11, 2024 · Hydrogen atoms are produced with the corrosion reaction between steel and hydrogen sulfide or carbon dioxide in oil and natural gas. Therefore, two types of corrosion have been recognized in pipeline steels including sweet corrosion and more common type corrosion [[68], [69], [70]]. The sweet corrosion in pipeline steels occurs when the carbon ... A common example of galvanic corrosion occurs in galvanized iron, a sheet of iron or steel covered with a zinc coating. Even when the protective zinc coating is broken, the underlying steel is not attacked. Instead, the zinc is corroded because it is less "noble". Only after it has been consumed can rusting of the base metal occur. By contrast, with a conventional tin can, the opposite of a protective effect occurs: because the tin is more noble than the underlying steel, wh…
