Surface finishing refers to all technical processes applied during the production of a part to improve its functional surface characteristics.
One example is corrosion protection. It is generated by galvanizing, chromium-plating, nickel-plating, anodizing, painting or powder-coating. Stainless steel is protected against corrosion by electrolytic polishing. Protection against wear and contamination is achieved by coating.
