Passivation Chemical PSV-72
1. Cleaning: Before passivation, the metal surface must be thoroughly cleaned to remove any contaminants, such as dirt, grease, oil, or residues from machining or fabrication processes. Cleaning is essential to ensure the effectiveness of the passivation treatment.
2. Passivation Chemical Application: Passivation chemicals like PSV-72 are applied to the cleaned metal surface. These chemicals typically contain acidic agents, such as nitric acid or citric acid, along with inhibitors and other additives to facilitate the formation of the protective oxide layer.
3. Passivation Treatment: The metal parts are immersed in or sprayed with the passivation chemical solution. The passivation treatment may also involve other methods, such as swabbing or brushing the solution onto the surface. The duration of the treatment and the specific conditions (e.g., temperature, concentration) may vary depending on the type of metal and the desired outcome.
