Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item. An unfinished surface is often called mill finish.
Surface finishing processes can be categorized by how they affect the workpiece:
- Removing or reshaping finishing
- Adding or altering finishing
Mechanical processes may also be categorized together because of similarities the final surface finish.

Famous quotes containing the words surface and/or finishing:
“A society which allows an abominable event to burgeon from its dungheap and grow on its surface is like a man who lets a fly crawl unheeded across his face or saliva dribble unstemmed from his mouth—either epileptic or dead.”
—Jean Baudrillard (b. 1929)
“When I am finishing a picture I hold some God-made object up to it—a rock, a flower, the branch of a tree or my hand—as a kind of final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there’s a clash between the two, it is bad art.”
—Marc Chagall (1889–1985)
