2. Deoxidization - Wikipedia

   en.wikipedia.org/wiki/Deoxidization

   Deoxidization is a method used in metallurgy to remove the rest of oxygen content from previously reduced iron ore during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food.

3. Galvanic anode - Wikipedia

   en.wikipedia.org/wiki/Galvanic_anode

   In brief, corrosion is a chemical reaction occurring by an electrochemical mechanism (a redox reaction). [1] During corrosion of iron or steel there are two reactions, oxidation (equation 1), where electrons leave the metal (and the metal dissolves, i.e. actual loss of metal results) and reduction, where the electrons are used to convert oxygen and water to hydroxide ions (equation 2): [2]

4. Dross - Wikipedia

   en.wikipedia.org/wiki/Dross

   It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal. For higher melting point metals and alloys such as steel and silver, oxidized impurities melt and float making them easy to pour off. With wrought iron, hammering and later rolling remove some dross. [1]

5. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   Fluxes are also used in foundries for removing impurities from molten nonferrous metals such as aluminium, or for adding desirable trace elements such as titanium. As reducing agents, fluxes facilitate soldering, brazing, and welding by removing oxidation from the metals to be joined. In some applications molten flux also serves as a heat ...

6. Hall–Héroult process - Wikipedia

   en.wikipedia.org/wiki/Hall–Héroult_process

   Alumina is added to the cells as the aluminum is removed. Collected aluminium from different cells in a factory is finally melted together to ensure uniform product and made into metal sheets. The electrolytic mixture is sprinkled with coke to prevent the anode's oxidation by the oxygen evolved. [1] The cell produces gases at the anode.

7. Weld purging - Wikipedia

   en.wikipedia.org/wiki/Weld_purging

   Weld purging is the act of removing, from the vicinity of the joint; oxygen, water vapour and any other gases or vapours that might oxidize or contaminate a welding joint as it is being welded and immediately after welding.
