2. Galvanic corrosion - Wikipedia

   en.wikipedia.org/wiki/Galvanic_corrosion

   In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system. Corrosion inhibitors such as sodium nitrite or sodium molybdate can be injected into these systems to reduce the galvanic potential. However, the application ...

   Tannic acid chemically converts the reddish iron oxides into bluish-black ferric tannate, a more stable material. [2] The second active ingredient is an organic solvent such as 2-butoxyethanol (ethylene glycol monobutyl ether, trade name butyl cellosolve) that acts as a wetting agent and provides a protective primer layer in conjunction with an ...

6. Electrochemical machining - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_machining

   B.R. and J.I. Lazarenko are also credited with proposing the use of electrolysis for metal removal. [2] Much research was done in the 1960s and 1970s, particularly in the gas turbine industry. The rise of EDM in the same period slowed ECM research in the West, although work continued behind the Iron Curtain. The original problems of poor ...

7. Electrometallurgy - Wikipedia

   en.wikipedia.org/wiki/Electrometallurgy

   The electrolysis can be done on a molten metal oxide (smelt electrolysis) which is used for example to produce aluminium from aluminium oxide via the Hall-Hérault process. Electrolysis can be used as a final refining stage in pyrometallurgical metal production (electrorefining) and it is also used for reduction of a metal from an aqueous metal ...

8. Electrolytic iron - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_iron

   As a result, iron is deposited on the surface of the cathode due to a difference in an ionization tendency, and high purity iron can be obtained. TOHO ZINC CO.,LTD. is producing and selling electrolytic iron refined by the wet process on an industrial scale. TOHO ZINC CO.,LTD. accounts for the top market share of high purity iron in wet type ...

9. Electrolytic process - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_process

   Electrolysis is usually done in bulk using hundreds of sheets of metal connected to an electric power source. In the production of copper, these pure sheets of copper are used as starter material for the cathodes, and are then lowered into a solution such as copper sulfate with the large anodes that are cast from impure (97% pure) copper.
