2. Galvanic series - Wikipedia

   en.wikipedia.org/wiki/Galvanic_series

   Galvanic series. The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the ...

3. Corrugated galvanised iron - Wikipedia

   en.wikipedia.org/wiki/Corrugated_galvanised_iron

   Corrugated iron in the Cobar Sound Chapel, used both for the roof and as the formwork for the concrete interior. Typical corrugated galvanised iron appearance, with visible large flake type patterns. The galvanised sheet is viewed from below and is supported by a piece of angle iron (painted white). Corrugated galvanised iron (CGI) or steel ...

4. Galvannealed - Wikipedia

   en.wikipedia.org/wiki/Galvannealed

   Galvannealed. Galvannealed or galvanneal (galvannealed steel) is the result from the processes of galvanizing followed by annealing of sheet steel. Galvannealed steel is a matte uniform grey color, which can be easily painted. In comparison to galvanized steel the coating is harder, and more brittle.

5. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   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]

6. Sendzimir process - Wikipedia

   en.wikipedia.org/wiki/Sendzimir_process

   Sendzimir process (named after Tadeusz Sendzimir) is used to galvanize a steel strip by using a small amount of aluminum in the zinc bath and producing a coating with essentially no iron -zinc alloy. The process guarantees high resistance and durability characteristics. About 75% of hydrogen was needed in the original Sendzimir process but all ...

7. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   Hot-dip galvanization. Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2 ...
