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.
Chemical cleaning is a vital aspect to many industrial processes, namely surface finishing. When dealing with electroplating, chemical cleaning is extremely effective in removing layers of oil and other substances. This is essential due to the fact that molecular layers of oil can prevent adhesion of the coating. Cleaning processes include the following:
- Solvent cleaning
- Hot alkaline detergent cleaning
- Acid etch
At ADV Plating, we offer a high quality alkaline cleaner bath that does an incredible job of cleaning parts and prepping them for our passivation and electroless nickel plating processes.
Bead blasting is the process of removing surface deposits in which fine glass beads are blasted at a high pressure without actually damaging the surface. Bead blasting is less damaging to the surface than typical abrasive blasting. ADV Plating offers a type of blasting called glass bead blasting. Glass bead blasting creates a clean, bright, uniform matte texture. Glass bead blasting can be used on a wide range of materials including:
- Stainless steel
- Sterling silver
This process is both an environmentally friendly and extremely effective form of cleaning.
