Surface finishing
Appearance
The term surface finishing is used to describe a number of industrial processes that can be applied to improve the surface of a manufactured item. These processes include (but are not limited to): Case hardening; Differential hardening; Electropolishing; Electroplating; Anodising; Painting and Shot peening. While the major reason to apply these processes is to improve appearance, corrosion protection, wear resistance and friction control also are areas where performance can be enhanced by these treatments. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item.
