[0002] Passivation treatment is usually the last process step in chemical cleaning and is a more critical step. Its purpose is to prevent corrosion of materials. For example, after the boiler is pickled, washed with water, and rinsed, the metal surface is very clean and very active, and it is very easy to be corroded. Therefore, passivation treatment must be carried out immediately to form a protective film on the cleaned metal surface to slow down or avoid corrosion.
[0003] When passivating a workpiece, a trivalent chromium solution is usually used for passivation treatment. The commonly used passivation treatment equipment is to immerse the workpiece in a trivalent chromium solution. The static state makes it difficult for the solution to penetrate into the interior of the workpiece, which not only makes the passivation effect inside the workpiece poor, but also affects the efficiency of the passivation treatment.
