-Cleaning: The surface must be thoroughly cleaned to remove any dirt, grease, or other impurities that may affect the treatment.
-Pickling: The metal surface is then treated under slightly acidic conditions, which helps to remove oxides and other impurities, while creating a better substrate for the next step.
-Passivation treatment: Typically done by immersion or spraying, specific chemical agents are used to react with the metal surface, forming a protective oxide layer. This helps prevent further oxidation, corrosion, or other surface damage.
-Neutralization and rinsing: Objects after treatment often need to be neutralized and rinsed to remove residual treatment agents, ensuring the surface is clean.
-Drying: Finally, the part need to be completely dried.
