Utilizing these finishing techniques often creates a visually pleasing aesthetic or decorative surface coating. Metal finishing can also add a protective layer that safeguards the part from environmental conditions. This process hardens the metal or protects against natural oxidation and rusting.
Because metals are often exposed to numerous elements preventing rust, oxidation and corrosion are the most common surface treatments in metal fabrication. Another reason to choose a metal finishing treatment is to improve the part’s functionality or increase durability.
On the opposite spectrum, surface finishing is techniques that remove aspects from the surface layer. These processes are functional coating utilized to change appearance, increase durability, or increase the functionality of a wide variety of metals.
In the same vein, removal processes create different aesthetics than adding treatments for a completely new finished look. Specific treatments also increase functionality and provide tighter tolerances.
