2. Polishing (metalworking) - Wikipedia

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

   The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer. This is of particular concern for copper alloy products such as brass and bronze.

3. Electropolishing - Wikipedia

   en.wikipedia.org/wiki/Electropolishing

   Electropolishing. Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.

4. Tumble finishing - Wikipedia

   en.wikipedia.org/wiki/Tumble_finishing

   Tumble finishing, also known as tumbling or rumbling, [1] is a technique for smoothing and polishing a rough surface on relatively small parts. In the field of metalworking, a similar process called barreling, or barrel finishing, [2] works upon the same principles. Tumbled stones are made with rock tumblers in a process very similar to the ...

5. Polishing - Wikipedia

   en.wikipedia.org/wiki/Polishing

   Polishing. Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1] In some materials (such as metals, glasses, black or ...

6. Chemical-mechanical polishing - Wikipedia

   en.wikipedia.org/wiki/Chemical-mechanical_polishing

   Chemical mechanical polishing (CMP) (also called chemical mechanical planarization) is a process of smoothing surfaces with the combination of chemical and mechanical forces. It can be thought of as a hybrid of chemical etching and free abrasive polishing. [ 1 ] It is used in the semiconductor industry to polish semiconductor wafers as part of ...

7. Surface finishing - Wikipedia

   en.wikipedia.org/wiki/Surface_finishing

   Surface finishing. A drill bit with surface finishing to make the cutting edges harder. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion ...
