Passivation of Stainless Steel
Passivation is a chemical process in which a material becomes passive, meaning the material is less affected by environmental factors, such as air and water. Passivation helps prevent corrosion and eradicates pitting on the surface of stainless steel. However, the true benefit of passivation comes from the formation of an inert surface layer. Many metals have a thin oxide layer already, making it naturally resistant to corrosion and rust. Passivation thickens that naturally occurring oxide layer.

Bright dips are used to give metals bright, lustrous finishes. ADV’s stabilized peroxide bright-dip processes help prevent re-tarnishing of brass, leaded brass, and copper after brightening.
A quick bright-dip process followed by a rinse, deoxidization, and a final rinse will result in a bright, bold, and eye-pleasing finish on metal parts.
Specification: ASTM B-281
Chemical cleaning is extremely effective in removing layers of oil and other substances. ADV Plating offers the following chemical cleaning processes:
- Solvent cleaning
- Hot alkaline detergent cleaning
- Acid etch
Specifications: ASTM B183 (Low Carbon Steel), ASTM B254 (Stainless Steel), ASTM B242 (High-Carbon Steel), ASTM B-281 (Brass, Copper)
Bead blasting is the process of removing surface deposits using glass beads blasted at high pressure. Bead blasting is less damaging to the surface than typical abrasive blasting and creates a clean, bright, uniform matte texture. This process is both an environmentally friendly and an extremely effective form of cleaning.
Glass bead blasting can be used on a wide range of materials including:
- Cast iron
- Stainless steel
- Sterling silver
