2. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   In 1801, Alessandro Volta furthered the research on galvanizing when he discovered the electro-potential between two metals, creating a corrosion cell. In 1836, French chemist Stanislas Sorel obtained a patent for a method of coating iron with zinc, after first cleaning it with 9% sulfuric acid (H 2 SO 4) and fluxing it with ammonium chloride ...

3. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   Galvanized surface with visible spangle. Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]

4. Electrogalvanization - Wikipedia

   en.wikipedia.org/wiki/Electrogalvanization

   Such Zinc electroplating or Zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot dip galvanizing and electroplating. [ 1 ]

5. Mechanical plating - Wikipedia

   en.wikipedia.org/wiki/Mechanical_plating

   Mechanical plating, also known as peen plating, mechanical deposition, or impact plating, is a plating process that imparts the coating by cold welding fine metal particles to a workpiece. Mechanical galvanization is the same process, but applies to coatings that are thicker than 0.001 in (0.025 mm). [ 1 ]

6. Zinc flake coating - Wikipedia

   en.wikipedia.org/wiki/Zinc_flake_coating

   Because electrolytically zinc-plated surfaces provide comparatively little corrosion protection, and in the case of galvanic zinc coatings on high-strength steel (e.g. category 10.9 and 12.9 high-strength bolts) there is a risk of hydrogen embrittlement, the industry needed a better corrosion protection system.

7. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Galvanized coatings are quite durable in most environments because they combine the barrier properties of a coating with some of the benefits of cathodic protection. [44] If the zinc coating is scratched or otherwise locally damaged and steel is exposed, the surrounding areas of zinc coating form a galvanic cell with the exposed steel and ...
