2. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   Polishing is often used to enhance the appearance of an item, prevent contamination of instruments, remove oxidation, create a reflective surface, or prevent corrosion in pipes. In metallography and metallurgy, polishing is used to create a flat, defect-free surface for examination of a metal's microstructure under a microscope. Silicon-based ...

3. 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 ...

4. Conservation and restoration of silver objects - Wikipedia

   en.wikipedia.org/wiki/Conservation_and...

   Along with buffing wheels, particular compounds are used to help polish the material. Two main types of compounds used for silver and gold surfaces are red and blue compounds. Red, also known as jeweler's rouge, polishes without any cutting action. The blue compound is a dryer compound and is used with a grease-less wheel that also does not cut ...

5. 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.

6. Vibratory finishing - Wikipedia

   en.wikipedia.org/wiki/Vibratory_finishing

   Despite the apparent rubbing action of particles against parts, studies [3] show that the primary mechanism of material removal in vibratory finishing is erosion caused by the relatively normal impacts of particles on parts. These impacts occur at the same frequency as the vibration, and at impact velocities of less than 1 m/s.

7. Lubricant - Wikipedia

   en.wikipedia.org/wiki/Lubricant

   Typically various filtration systems remove particulates, additives, and oxidation products and recover the base oil. The oil may get refined during the process. This base oil is then treated much the same as virgin base oil however there is considerable reluctance to use recycled oils as they are generally considered inferior.
